How does MP3 compression impact transient audio signals?

Let’s talk about MP3 Compression

When we talk about MP3 compression, we’re delving into the world of digital audio. As a specialist with experience in the area, I’ve seen how MP3 revolutionized how we store and consume music. It’s like packing a suitcase for a trip, but in this case, we’re packing audio data efficiently.

Understanding Transient Audio Signals

Now, let’s understand transient audio signals. Think of a musical note—the initial, sharp attack you hear before it settles into a sustained sound. That attack is the transient. It’s the snap of a drumstick, the pluck of a guitar string, or the click of a piano key. These transients carry vital musical information, and we must preserve them.

MP3 Compression and Audio Signal Loss

MP3 compression is all about making audio files smaller without sacrificing too much quality. But here’s the catch: compression can affect transients. It’s like taking a high-resolution photo and reducing it to save space. Some fine details get lost in the process. When we compress audio, we’re essentially doing the same thing.

Bitrate and its Impact on Transients

Now, let’s talk bitrates. They’re like the resolution settings on your camera. Higher bitrates capture more detail, but they result in larger files. In MP3, higher bitrates preserve transients better, but they also produce larger files. Lower bitrates, on the other hand, reduce file size but at the cost of transient detail.

The Listener’s Perspective

As someone who’s explored the intricacies of audio, I can tell you that the impact of MP3 compression on transients varies from one listener to another. Some may not notice a significant difference, while others with a keen ear might cringe at the loss of those sharp drum hits or guitar strums. It’s like viewing a beautiful landscape through a slightly foggy window—still enjoyable, but not as clear.

Preserving Transients: Best Practices

If you’re an audiophile who values those transients, there are ways to preserve them. Audio engineers use various techniques during the production process to minimize transient loss. It’s akin to an artist carefully protecting their masterpiece. By using higher bitrates and understanding the nuances of compression, it’s possible to maintain those musical gems.

Latest Words on MP3 Compression and Transients

In this article, we’ve delved deep into the impact of MP3 compression on transient audio signals. As a specialist, I believe it’s essential to appreciate the trade-off between file size and audio quality. In today’s digital age, MP3 remains a popular format, and understanding its impact on transients is crucial for both creators and listeners.

As Google’s algorithm prioritizes comprehensive responses, I’ve aimed to provide a better understanding of how MP3 compression affects those vital musical moments—the transients. As we continue to enjoy digital audio, let’s listen closely and savor every note, transient, and melody.

Comments:

I never really thought about transients before. This article opened my ears to a whole new world of audio! Kudos!

Great article! I’m an aspiring musician, and this helped me understand why my tracks sometimes lose their punch after compression. More articles like this, please!

I appreciate the clear explanations. I’m not a techie, but I could follow along. However, I’d love to read about specific software or tools that can help preserve transients. Keep up the good work!

I use MP3s all the time, and now I’ll listen more carefully to those transients. This article added a new layer to my music experience. Thank you!

Top secrets on: How to choose the right audio format to get the best audio quality?

Choosing the right audio format is crucial for achieving the best audio quality. With so many options available, it can be overwhelming to determine which format is ideal for your needs. In this article, we will explore the top secrets and expert tips on how to choose the right audio format that will enhance your listening experience.

1. Understand the Different Audio Formats

To make an informed decision, it’s essential to understand the various audio formats available. Some popular formats include MP3, FLAC, WAV, AAC, and OGG. Each format has its own advantages and disadvantages, such as file size, compression, and compatibility. By familiarizing yourself with these formats, you can narrow down your options and choose the one that suits your requirements.

Quote: “Music is the universal language of mankind.” – Henry Wadsworth Longfellow

2. Consider Audio Quality and File Size

When selecting an audio format, it’s crucial to strike a balance between audio quality and file size. Lossless formats like FLAC and WAV offer the highest audio quality but result in larger file sizes. On the other hand, lossy formats like MP3 and AAC provide smaller file sizes but sacrifice some audio quality. Assess your priorities and determine whether you prioritize pristine audio quality or a smaller file size that saves storage space.

Quote: “The only truth is music.” – Jack Kerouac

3. Evaluate Device Compatibility

Before settling on an audio format, consider the devices you’ll be using to play the audio files. Not all formats are universally supported across different devices and platforms. For example, if you primarily listen to music on your smartphone, ensure that the chosen format is compatible with your device’s operating system and media player. Compatibility issues can lead to playback problems or the need for additional software or conversions.

Quote: “Without music, life would be a mistake.” – Friedrich Nietzsche

4. Assess Storage and Bandwidth Constraints

Storage space and bandwidth limitations are crucial factors to consider, especially if you plan to store or stream audio files. Lossless formats consume more storage space and require higher bandwidth for streaming, which may not be feasible if you have limited resources. Evaluate your storage capacity and internet connection to determine whether you can accommodate larger file sizes or if you need to prioritize smaller, more compressed formats.

Quote: “Music expresses that which cannot be said and on which it is impossible to be silent.” – Victor Hugo

5. Take into Account Metadata and Tagging

Metadata and tagging play a significant role in organizing and managing your audio library. Some formats support extensive metadata, including album art, track information, and lyrics. If you value a well-organized music collection, consider formats that allow comprehensive tagging. This way, you can easily search, sort, and display relevant information about your audio files.

Quote: “One good thing about music, when it hits you, you feel no pain.” – Bob Marley

6. Consider Future Compatibility

Technology is constantly evolving, and audio formats may become obsolete over time. When choosing an audio format, consider its future compatibility. Look for formats that have stood the test of time and are widely supported across different platforms. Opting for a format with broad compatibility ensures that your audio files will remain accessible and playable in the future.

Quote: “Music is the strongest form of magic.” – Marilyn Manson

7. Seek Expert Recommendations

If you’re still unsure about which audio format to choose, seek recommendations from experts or audio enthusiasts. Online forums, communities, and audio-related websites can provide valuable insights and guidance. Engage in discussions, ask questions, and learn from the experiences of others. Their expertise can help you make an informed decision and discover lesser-known audio formats that might suit your needs.

Quote: “Music is the soundtrack of your life.” – Dick Clark

8. Test and Compare Audio Formats

To truly determine the audio format that provides the best quality for your ears, conduct your own tests and comparisons. Take a sample audio file and convert it into different formats. Listen to each version carefully, paying attention to nuances, clarity, and overall sound quality. By directly comparing the formats, you can make a subjective judgment based on your personal preferences and the audio equipment you use.

Quote: “Music is the art of thinking with sounds.” – Jules Combarieu

9. Consider the Source of Audio Files

The source of your audio files can also influence the choice of format. If you primarily obtain music from online stores or streaming services, they may offer files in specific formats. Consider the compatibility of these formats with your devices and whether they meet your desired audio quality standards. Additionally, if you rip audio from CDs or vinyl records, ensure that the chosen format preserves the original audio fidelity.

Quote: “Music is the greatest communication in the world. Even if people don’t understand the language that you’re singing in, they still know good music when they hear it.” – Lou Rawls

10. Experiment and Trust Your Ears

Ultimately, the choice of audio format is subjective and depends on your personal preferences. Experiment with different formats and trust your ears to guide you. Listen to various genres of music, podcasts, or audiobooks in different formats to determine which one delivers the best audio quality and overall listening experience for you. Remember, the goal is to enjoy the music or audio content in a format that resonates with you.

Quote: “Music is the wine that fills the cup of silence.” – Robert Fripp

Final Words

Choosing the right audio format is a crucial step in ensuring an immersive and high-quality audio experience. By understanding the different formats, considering audio quality and file size, evaluating device compatibility, and taking other factors into account, you can make an informed decision. Remember to experiment, seek expert recommendations, and trust your ears to find the audio format that best suits your needs and preferences.

Digital Audio Quality

Data rate refers to the data flow used by a video file in a unit of time, also called bit rate or bit stream rate.

The popular interpretation is the sampling rate, which is the most important part of image quality control in video encoding. Generally, the units we use are kb/s or Mb/s. Generally speaking, at the same resolution, the higher the code stream of the video file, the lower the compression ratio and the higher the image quality. The higher the code stream, the higher the sampling rate per unit time, the higher the data stream, the higher the accuracy, the closer the processed file is to the original file, the better the image quality, the clearer the image quality and the higher the decoding capability of the playback device is required.

Of course, the larger the code stream, the larger the file size. The calculation formula is file size = time X code rate/8. For example, a 720P RMVB file with a 1 Mbps stream of 90 minutes is common on the Internet and its volume is = 5400 seconds × 1 Mb/8 = 675 MB.

Generally speaking, a video file includes images and sounds, just like an RMVB video file, which contains video information and audio information. Audio and video have their own sampling methods and different bit rates, that is, the same video Audio and video file bit rate is not the same. And what we’re talking about is the bitrate of a video file, which generally refers to the sum of the bitrate of the audio and video information in the video file.

Taking the most popular and familiar RMVB video file in China as an example, VB in RMVB refers to VBR, which is short for Variable Bit Rate. The Chinese meaning is variable bit rate, which means that RMVB adopts dynamic encoding. In this way, a higher sample rate is used for complex dynamic images (singing and dancing, flying cars, wars, actions, etc.), while a lower sample rate is used for static images, and the resources are use rationally to achieve image quality and volume .Effect.

The most fundamental difference between code rate and sample rate is that the code rate is for the source file.

2. Sampling rate

Sample rate (also called sample rate or sample rate) defines the number of samples per second taken from a continuous signal to form a discrete signal, and is expressed in hertz (Hz). Sampling rate refers to the sampling frequency when converting an analog signal to a digital signal, i.e. how many points are sampled per unit of time. How many bits are in the data for a sample point? Bit rate refers to the number of bits (bits) transmitted per second. The unit is bps (bit per second). The higher the bitrate, the more data transmitted and the better the sound quality. Bit rate = sample rate x number of bits used x number of channels.

The sample rate is similar to the number of frames of moving images. For example, the sampling rate of movies is 24 Hz, the sampling rate of PAL format is 25 Hz, and the sampling rate of NTSC format is 30 Hz. When we play back the still images sampled at the same rate as the sampling frequency, we see a continuous image. In the same way, when a CD recorded at a sampling rate of 44.1 kHz is played back at the same rate, a continuous sound can be heard. Obviously, the higher the sample rate, the more coherent the sound will be heard and the picture will be seen. Of course, the sampling rate that human auditory and visual organs can distinguish is limited, which is basically higher than sound sampled at 44.1 kHz, and most people haven’t noticed the difference.

The number of digits in the sound is equivalent to the number of colors on the screen, indicating the amount of data per sample. Of course, the larger the amount of data, the more accurate the playback sound, so as not to confuse the sound. of the teapot with the train whistle. In the same way, it is more clear and precise for the image, so as not to confuse blood and ketchup. However, limited by the function of human organs, 16-bit sound and 24-bit image are basically the limits of ordinary humans, and the highest digits can only be distinguished by instruments.

Detailed Music Format Part 2

Music CD

That is, CD records. A CD can play sound files of approximately 74 minutes. The Windows system comes with a CD player. Also, the software that comes with most sound cards provides CD playback functionality, and even some CD-ROM drives are offline. from computer Can be used as a stand-alone CD player when powered on.

WMA with unlimited potential

In developing its own network media service platform, Microsoft primarily promotes ASF (Audio Streaming Format), which is an open standard that supports data transmission over various networks and protocols. It supports audio, video, and a variety of other types of multimedia. And WMA is short for Windows Media Audio, which is equivalent to an ASF file that contains only audio.
The compression ratio of WMA files can be as high as 1:18 in 80kbps 44kHz mode, which is basically the same as VQF. And the compression speed is doubled compared to MP3. So it should be more competitive than VQF.

Vorbis free music format

To avoid rising royalties charged by MP3 music companies, programmers at GMGI’s iCast company developed a new free music format, Vorbis, that rivals or even exceeds MP3 in sound quality. And it will be released over the internet and can be downloaded for free without worrying about infringement issues. But MP3 has become very popular on the Internet, and Microsoft’s Windows Media technology has also started to spread, and Vorbis’s outlook is still not optimistic.

Other audio formats

AIF/AIFF: A sound file format developed by Apple, supported by the MAC platform, and supports 16-bit stereo at 44.1 kHz.
AU: SUN’s AU Compressed Sound File Format, which only supports 8-bit sound, is a commonly used sound file format on the Internet, mainly created by SUN workstations.
CDA: CD audio track file.
CMF: A MIDI-like sound file developed by CREATIVE.
DSP: Abbreviation for digital signal processing. By improving the signal processing method, sound quality will be greatly improved and songs will be more pleasing to the ear.
S3U: MP3 playback file list
RMI: MIDI Instrument Sequence

Lossy compression:

AAC – Sound quality is second only to MPC at high bit rates and looks good at both high and low bit rates. The encoding speed is too slow!
MPC: Performance is average at low bitrate, not as good as MP3 and OGG encoded by Mp3Pro, sound quality is best at high bitrate, and encoding speed is
fast.OGG: The sound quality is better at a low bitrate, and the same is true at a high bitrate. Encoding is slightly slower.
MP3 (MP3Pro): Sound quality is lower than OGG at low bit rate and other aspects are the same as MP3
WMA: High and low bit rates are average, VBR is not supported and the highest is 192Kbit/s

lossless compression:

FLAC – Worst compression ratio of the four, decent encoding speed, good platform support.
PAC: Slightly slower encoding speed, third in compression ratio, good platform support.
APE: The fastest encoding speed, the best compression rate, and the platform is generally supported.
WV: The encoding speed is very fast, the compression rate is second among the four types, and it is only supported by the Windows platform.

Detailed music format

classic wave

As the most classic Windows media audio format, the WAVE file is widely used, which uses three parameters to represent sound: the number of sampled bits, the sample rate, and the number of channels.
The channels are divided into mono and stereo, and the sample rates are generally 11025 Hz (11 kHz), 22050 Hz (22 kHz), and 44100 Hz (44 kHz). The capacity occupied by the WAVE file = (sampling frequency × sampling bits × channel) × time/8 (1 byte = 8 bits).

traditional mod

MOD is a wavetable-like music format, but its structure is similar to MIDI, it uses real samples, and the volume is small. In the earlier DOS era, MOD was often used as background music for games. Modern mods can contain many audio tracks in many formats, such as S3M, NST, 669, MTM, XM, IT, XT, and RT.

midi music computer

MIDI is short for Musical Instrument Data Interface. Records the sound played by the instrument digitally (each note is recorded as a number), and then synthesizes these records via FM or wavetable during playback: FM synthesis is the sound of the instrument is simulated by mixing the multi-frequency sounds; wavetable synthesis consists of storing the sound samples of the instrument in the wavetable of the sound card and extracting the sound from the wavetable as you play.

Boss Boss MP3

It can be said that MP3 is famous, it uses MPEG Audio Layer 3 technology to compress the sound with a compression ratio of 1:10 or even 1:12, with a sampling rate of 44kHz and a bit rate of 112kbit/s. .
MP3 music is music stored in digital form. If you want to play it, you must have a corresponding digital playback and decoding system. Generally, MP3 digital music is decoded by special software and then restored to a waveform sound signal for playback output. This type of software is called For MP3 players, such as Winamp, etc.

Overlord RA series online

RA, RAM, and RM are Real’s mature network audio formats, using “streaming audio” technology, making them well suited for network streaming. Information such as copyright, singer, producer, mail and song title can be added during production.
RA can be called the supreme lord of multimedia communication on the Internet. It is suitable for streaming on the Internet and is currently the best format for listening to online music online.

VQF with high compression ratio

VQF or TwinVQ is an audio compression technology developed by Nippon Telegraph and Telephone and Yamaha Corporation.
The audio compression rate of VQF is almost twice that of standard MPEG audio and can reach approximately 1:18 or even higher. And popular compression formats like MP3 and RA are usually only around 1:12. But it still won’t affect the sound quality, when VQF compress music at 44kHz-80kbit/s audio sampling rate, its sound quality will be better than 44kHz-128kbit/s MP3, when compress at 44kHz-96kbit/s , the music is close to 44kHz-256kbit/s MP3.

MD minidisc

MD (ie MiniDisc) is a comprehensive portable music format released by SONY in 1992. The compression algorithm it uses is ATRAC technology (the compression ratio is 1:5). MD is divided into Recordable MD (Recordable, with two heads of magnetic head and laser head) and Single Play MD (Prerecorded, only laser head).
The powerful editing function is the strong point of MD. You can quickly select tracks, move tracks, merge, split, delete and edit track titles. It is more personalized than CD and you can have your own MD album at any time. MD products include MD Walkman, MD bedside audio, MD car audio, MD recording deck, MD camera gun and MD driver, etc.

Overview in the jungle of audio formats

Overview in the jungle of audio formats

Size does not necessarily matter, especially with compressed audio files. The deciding factor here is the algorithm that is used during encoding. Meanwhile, there are quite a few, but not all of them harmonize with iTunes, iPod & Co. We provide an overview of supported formats and introduce the general working method of audio compression.

Since Philips introduced the audio CD in 1982, digitally stored music has been ubiquitous. However, since then, the number of digital data formats available has become so great that it is very easy to lose sight of things. There are basically compressed and uncompressed formats. The uncompressed WAV and AIFF formats are mainly used in audio media production due to their file size and high quality of the audio signal, and still on good old audio CDs.

Compression and reduction

Formats like Apple Lossless manage to reduce the amount of data without reducing the quality of the signal. This lossless encoder procedure is called data compression. However, you still have to live with relatively large files. This can quickly lead to difficulties, especially when gaming on mobile devices, as the battery drains very quickly. On a fourth-generation iPod, AAC-compressed music could only be played for three and a half hours in the test. However, when highly compressed audio books were used, it was more than ten hours. The other lossy processes accept a loss of quality in exchange for the advantage of a small file size. Here, the original quality of the music signal cannot be restored during playback. These compression processes make use of certain properties of human hearing to reduce data: the brain simply masks sound signals that are considerably quieter than other sounds that are perceived at the same time. Another effect that has been exploited is that there must be a minimal difference in the frequency of the tones to be able to distinguish them and to be able to perceive them consciously. Here there is also the possibility of saving. The encoder just skips everything within the specified bit rate that the brain would also leave out in its opinion. If the bit rate is set too low in relation to the complexity of the audio signal, you will inevitably notice signal interference, so-called artifacts, during decompression, that is, you will notice that the original has been compressed.

Bit rates for everyone and everything
Lossy encoders, unlike lossless encoders, can compress source material with different bit rates. The results are qualitatively very different. As a general rule, the average listener can no longer distinguish what is heard from the original signal of a bit rate of 160 kbps for MP3 and 128 kbps for AAC. However, this only applies to music; audiobooks, for example, can be compressed much more without incurring excessive losses. Bit rates of 96 kbps are sufficient for good results. Modern versions of encoders, including iTunes, can also compress the audio signal with a variable bit rate (VBR). The complexity of the source material is checked. If a passage is not very elaborately designed, the encoder automatically regulates the bit rate and saves space for more complicated parts. There it increases the bit rate again to improve the result. The option in iTunes to select the encoder settings and the encoder itself can be found in iTunes -> Settings -> Advanced -> Import. From encoder to bit rate to variable bit rate, you can choose the one that best suits your needs and needs from many options.

AIFF
This data format is not compressed and corresponds to the original data on an audio CD. Therefore, a large file size is expected. A music CD usually contains 80 minutes of music with a size of 700 MB. Therefore, this format is a bit difficult to handle. AIFF isn’t doing itself a favor, especially on mobile music players, as the battery capacity drains very quickly.

Wav
In principle, what has been said above also applies to WAV files, the two formats are very similar. This format is also usually uncompressed, but there are also variants with compression.

MP3
The MP3 data format, strictly speaking the MPEG1 Audio Layer 3 standard, was one of the first to achieve high data compression and therefore a reduced file size. In times of Internet connections via modem, it quickly found widespread use. Today’s encoders come with a variety of possible VBR and bit rates, so there is something for every purpose.

Lossless apple
This can be used to create files that have no signal loss compared to the original when played back. However, the files are quite large and the bit rate is usually over 900 kbps. Therefore, this format is less suitable for mobile devices due to the shorter battery life.

AAC and protected AAC
This encoder is a further development of MP3 and generally works better than MP3 encoders. Protected AAC files have rights management (music files purchased from the iTunes Music Store are in this format).

Audible
Audiobooks purchased from Audible.com come in a file format that is a variation of AAC. The files have the extension .m4b. This file format supports bookmarks so you can continue listening to an audiobook where you last left it.

Windows Media Audio on Mac
Since Windows Media Player no longer exists for the Mac operating system, the Flip4Mac company has been offering a QuickTime component that allows you to open Windows Media files directly in QuickTime Player. However, digital rights management files cannot be played. WMA files offered by some internet music stores (eg Musicload.de) cannot be played with this solution. iTunes is also not supported. You can find an installer for the component on our brochure CD under Software -> Mac -> WMA Components 2.2.0.49R.dmg.

OGG Vorbis Audio
The OGG format, which is free of software patents, can be added to iTunes at a later date. The required QuickTime components can be found under Software -> Win -> OGG_xiph-qt-win32-0.1.5.exe or Software -> Mac -> OGG_xiph-qt-0.1.8.dmg on our brochure CD. After installation with the supplied installation program in the respective operating system, both QuickTime and iTunes can play OGG files. However, all iPod and iPhone models still cannot play OGG.

Audio formats

Before going through the different audio formats to identify the best ones for you, it seems right to try to make you understand what digital audio is. In short, it is nothing more than a representation of real sounds through a chain of zeros and ones. The more there is in a file, the closer the digital sound will be to what it represents.

Better audio formats

It all started with Pulse-Code Modulation (PCM), created in 1937 and characterized by two properties: the sampling frequency to measure the amplitude of the waveform and the bit depth to measure possible digital values. It is basically the faithful conversion of analog audio into a digital file in which no compression is done. The result is a very large audio file, which takes up a lot of space.

To remedy this, therefore, more or less compressed audio formats have been created that, depending on their characteristics, are divided into two different types: Lossless formats, that is, when the information contained in the final file is identical to that contained in the source file and therefore there is no loss of quality, and lossy formats, for which the information contained in the final file is less than that contained in the source file with the consequent loss of quality but in benefit of the space of necessary storage. For more details, continue reading, below you will find the different audio formats belonging to the categories in question indicated and explained.

Lossless (WAV, AIFF, FLAC and ALAC)

As I told you a few lines above, Lossless audio formats are those that are not compressed or that, despite being subjected to this type of treatment, the final quality remains practically unchanged with respect to the original audio. The main formats that belong to this category are the following: WAV, AIFF, FLACC, ALAC and APE. Let’s see its characteristics in detail.

WAV – An acronym for WAVEform audio file format, is a standard that was developed by Microsoft and IBM in 1991. It is the most popular category of apparent audio file format. It is not compressed and is essentially what you get when you rip audio from a music CD with your computer. It takes up a lot of space (1,411 kilobits of information per second of stereo music at 44,100 Hz / 16 bits), but it reproduces sounds faithfully. In terms of quality and quantity of information, it is similar to the AIFF format, which you will find explained below.
AIFF – Short for Audio Interchange File Format, it belongs mainly to the Mac world, it was developed by Apple based on the Electronic Arts Interchange File Format and is particularly suitable for audiophiles and music recorders. It basically has the same characteristics as the WAV format mentioned above, so it is not compressed, so it takes up a lot of space (1,411 Kilobits of information per second of stereo music at 44,100 Hz / 16 bits) and is capable of reproducing sounds with a lot of fidelity.

FLAC: is the abbreviation for Free Lossless Audio Codec. It is an open source codec that is often used to store music CDs on the computer without loss of quality and is compatible with most programs and devices. Compared to the formats that I have already told you about, it has a minimal degree of compression, but most people cannot perceive significant differences compared to a WAV or AIFF file.
ALAC – Short for Apple Lossless Audio Codec, is essentially Apple’s worldwide counterpart to the earlier FLAC format. The quality is good on average but the format is not as efficient as the FLAC in terms of weight. Then keep in mind the fact that not all gamers support it, so unless you have uniquely and exclusively Apple devices, it may not be the best solution to opt for.

Other important but less common audio formats that always belong to the Lossless calorie are Monkey’s Audio (APE) and OptimFROG (OFR). Its characteristics are more or less similar to those of the FLAC and ALAC formats.

Lossy (MP3, AAC, WMA, and Ogg Vorbis)

Now let’s move on to the audio formats belonging to the Lossy category, that is, those always subjected to compression that take up very little space but “sacrifice” a certain degree of audio quality. The main formats in this category are: MP3, AAC, WMA, and Ogg Vorbis. For more information, keep reading, you will find more details about it below.

MP3: in Full Moving Picture Expert Group-1/2 Audio Layer 3, also known as MPEG-1 Audio Layer III or MPEG-2 Audio Layer III.

Mp3, the winner

In the era of broadband connections, fiber optics and HD videos on YouTube, MP3 remains the reference format for audio files. We are now so used to listening to music in compressed formats, and often through poor quality playback systems, that it is difficult for us to remember what listening to music really means. The recent evolution from download to hit-and-run streaming has only made the situation worse by further devaluing the value of music. When was the last time you listened to a record from start to finish without interruption, spending those 30-40 minutes on “simple” listening activity?

Premise: This post is not a crusade against Spotify because I use it myself for new releases or to have some background music at work, it is not even an analog vs. digital (or vinyl vs. CD vs. MP3) post because on this topic en Much has already been said. My goal is to make you understand what you are missing, in qualitative terms, if you listen to music in compressed formats.

Sampling and theoretical aspects.

Audio recording on a computer or digital medium assumes that the signal passes through an analog> digital (AD) converter, so that the continuous electrical signal generated by microphones or musical instruments is transformed into a digital signal (series of 0 and 1) This process is called sampling. The final quality of the recording depends on several factors: converter quality, sample rate, and bit depth.

To make an easily understandable comparison: When shooting a movie, the “analog” reality perceived by our eye is stored in a movie that takes 24 frames per second. If we consider the standard of the audio CD (44.1 kHz, 16 bits), for every second of music 44100 pictures are taken from the computer to the continuous electrical signal. If with the sampling frequency we have simply established how many times in a second the waveform will be analyzed, with the bit depth we assign to each sample a numerical value: 2 ^ 16 = 65,536 possible values.

If you wonder how it got to 44,100, I refer you to the Nyquist-Shannon sampling theorem.

When we press the record button on our computer, through the PCM (pulse code modulation) sampling process described above, the files are saved in uncompressed WAV or AIFF format.

Lossless files and lossy files

PCM files take up a lot of space on our hard drives because, as we have seen, there is the data necessary to describe the analog waveform in as much detail as possible. Indicatively, a WAV or AIFF file as audio CD will occupy 10 MB for every minute of music.

To overcome this problem, remember that in the early 2000s storage space cost around $ 10 / GB, while today the price is around $ 0.03 / GB (source): Audio formats have been introduced that , through an algorithm encodes and decodes information, reduces the size of the file. These codecs fall into two categories: formats with lossless compression and formats with lossy compression.

As the name implies, lossless compression indicates a reduction in file weight (usually around 50%) without loss of information. Leaving the world of audio aside for a second, ZIP and RAR files are clear examples of this type of compression: at any time we can “unzip” such a file and have access to the original information again without this no way has changed.

The most common file formats are: FLAC (Free Lossless Audio Codec) and ALAC (Apple Lossless Audio Codec).

Lossy compression, on the other hand, implies that some of the original audio information is somehow removed to obtain a file that weighs even 90% less than the PCM.

By what criteria is information removed without “compromising” the original audio too much? Since our hearing is an imperfect instrument, codecs exploit two principles of psychoacoustics: the minimum threshold of audibility (the human ear does not perceive all frequencies in the range between 20Hz and 20kHZ equally) and masking (a weaker sound). is masked, making it inaudible, by a louder sound.)

Compression algorithms, however advanced, introduce a number of artifacts into audio files that, if played back in discrete quality audio systems, can be easily recognized or at least noticed even by an inexperienced ear. Several studies have shown that an untrained ear does not distinguish the difference between an uncompressed file and an MP3 with a bit rate equal to 256kb / s or more.

The most common lossy formats are: MP3, OGG Vorbis, AAC.

The victory of MP3

Since its introduction in the mid-1990s, MP3 has established itself as the industry-standard consumer format fueled by file-sharing through peer-to-peer channels, where, with slow connections, the heaviest file was the one it was downloaded, the longer it took to obtain it, and since the market introduction of MP3 players in which we tried to store as much music as possible and, therefore, we resorted to very compressed files.

In the transition from the era of downloading to that of small transmission files, they ensure smoother and smoother data transmission.

Despite, therefore, the evolution that has taken place in recent years in the speed of Internet connections and the reduction in the price of storage systems, only in recent years have services been created to buy files from High-quality online audio (HD tracks) or HD streaming services (Tidal).

Examples and audio files.

The main services we use to buy or listen to music use these compression levels (all information is taken from the official websites of each service at the time this publication was written).

Spotify: OGG Vorbis files at 96 kb / s (normal mobile quality), 160 kb / s (normal desktop and web player quality, high mobile quality), 320 kb / s (premium users: high desktop quality, very high quality mobile).
iTunes: By default, CDs are imported into 128 kb / s AAC files. Files in the iTunes Store are of this quality, except for “iTunes Plus” songs converted to AAC at 256 kb / s.
Pandora: 64kb / s AAC (free users), 192kb / s AAC (premium users).
YouTube: HD videos (720 or 1080p) have an audio quality equal to 384kb / s, SD videos (360, 480p) have an audio quality equal to 128kb / s.

Do you know what is the best audio format? (for musicians and listeners)

Maybe you are a musician who has had the hard work of learning sound theory, writing and arranging your music, practicing, recording, and now you want to show your work to the world. What is the best audio format to distribute your recording? Or maybe you are a music lover looking for the best way to organize your collection. It may be that your collection comes from CDs or vinyl or even digitally downloaded. What is the best audio format to store your collection?

Choosing the right file format is important. On the one hand, the selected format affects the fidelity of the sound. However, the selected format also limits which devices can play your files. In this guide, we explain the different audio formats available, what they offer and how they are used in the best possible way. First, let’s understand what digital audio files are.

In short, what is the best audio format for you?
To choose the best audio file format you need, think about the purpose of each file. Here are some common uses with suggestions for the best audio formats for each:

If you are an artist …

Do you record a CD with your work? WAV! Conventional CDs use WAV, so export your music from DAW to Wav (or other lossless and then convert properly) and use these files to burn to CD. If you compress CDs from a factory, export in wav but in the original sampling rate and bit depth settings. Leave these settings to them.
Do you share your music with the public? Lossy! You want a smaller file size and maximum compatibility with them from your listeners. Any device plays an MP3 file and is easy to share online.
Should you distribute your music with Magroove or another aggregator for streaming services and online music stores? Streaming services have their own conversion systems, and each one works in a different format (the vast majority, lossy), so you probably won’t get a lossless song. Get a good mp3 that survives encoding (and is easier to load) and save Lossless versions somewhere, whether burning to CD or distributing to acts overseas!
If you are a listener or a collector …
Are you archiving your music? FLAC with maximum compression! A lossless compressed format such as FLAC or ALAC lets you store your files efficiently without losing sound quality. Records in the original multimedia format settings. CD, for example, 16-bit, 44.1 kHz.
Do you digitize music from a vinyl? Record at least in a lossless format. Read about the recording / conversion settings, especially sample rate and bit depth, and understand what lossless quality you need.
