The Role of Audio Codecs in Digital Music

How do audio codecs impact the quality of digital music?

Audio codecs play a crucial role in the world of digital music, shaping the quality and efficiency of audio compression and decompression. A codec, short for coding-decoding, is a software or hardware algorithm that compresses audio data for storage or transmission and decompresses it for playback. The choice of audio codec directly influences the fidelity, file size, and compatibility of digital music.

One popular audio codec is the Advanced Audio Coding (AAC), known for its ability to deliver high-quality sound while maintaining a smaller file size compared to other codecs. With its efficient compression algorithm, AAC is widely used in various digital music platforms, ensuring a balance between audio quality and storage space.

The Importance of Lossy and Lossless Audio Codecs

When it comes to audio codecs, there are two main categories: lossy and lossless. Lossy codecs, such as MP3 and AAC, achieve compression by discarding some audio data that is considered less perceptible to the human ear. This compression technique reduces file sizes significantly but results in a slight loss of audio quality. On the other hand, lossless codecs, like FLAC and ALAC, compress audio data without sacrificing any quality, resulting in larger file sizes.

Striking the Balance between Quality and File Size

Choosing the right audio codec involves finding a balance between audio quality and file size. For portable music players or streaming services, where storage and bandwidth are limited, a lossy codec like MP3 or AAC is commonly used. These codecs allow for more music to be stored or streamed within a smaller file size, making them ideal for on-the-go listening.

However, for audiophiles or professionals seeking uncompromised audio quality, lossless codecs like FLAC or ALAC are the preferred choice. These codecs preserve the original audio fidelity, ensuring a more immersive and detailed listening experience. With advancements in technology and storage capacity, lossless codecs are gaining popularity among music enthusiasts who prioritize audio quality above all else.

The Impact of Audio Codecs on Digital Music Streaming

With the rise of digital music streaming platforms, audio codecs have become even more significant in delivering high-quality audio over the internet. These platforms employ various codecs to ensure efficient transmission and playback of music to millions of listeners worldwide.

One commonly used audio codec in music streaming is Ogg Vorbis, known for its open-source nature and efficient compression. Ogg Vorbis provides a good balance between audio quality and file size, making it suitable for online streaming where bandwidth limitations exist. Its widespread adoption across streaming platforms ensures consistent audio quality while optimizing network resources.

Adaptive Streaming and Codecs

Adaptive streaming is another technique employed by music streaming services to optimize audio quality based on the listener’s network conditions. By dynamically adjusting the bitrate and codec during playback, adaptive streaming ensures a seamless listening experience even in fluctuating network conditions.

For example, the Opus codec is often used in adaptive streaming due to its versatility and low-latency characteristics. Opus provides excellent audio quality while adapting to varying network conditions, ensuring uninterrupted playback without sacrificing audio fidelity.

Final Words

Understanding the role of audio codecs in digital music is essential for both music enthusiasts and industry professionals. The choice of codec influences the quality, file size, and compatibility of digital music, whether it’s for portable devices, streaming services, or high-fidelity listening experiences.

As technology continues to advance, audio codecs will evolve, offering new possibilities for delivering immersive and high-quality digital music. Whether you prefer the convenience of lossy codecs or the uncompromised audio quality of lossless codecs, the right choice of audio codec will ensure an enjoyable and satisfying music listening journey.

Understanding Audio Codecs: MP3, AAC, and Ogg Vorbis

AIntroduction

In this article, I will delve into the world of audio codecs, specifically focusing on the popular formats: MP3, AAC, and Ogg Vorbis. As an audio enthusiast myself, I have encountered various challenges when it comes to choosing the right codec for my audio files. Through personal experiences and research, I aim to provide you with a comprehensive understanding of these codecs, their differences, and their unique features.

MP3: The Pioneer of Audio Compression

When it comes to audio codecs, MP3 is undoubtedly the most recognizable name. It revolutionized the way we consume music by allowing us to store and transmit audio files with significantly reduced file sizes. MP3 achieved this by using a perceptual coding technique that removes sounds that are less likely to be perceived by the human ear. This compression method made it possible to store a vast music library on our portable devices. As one of the most widely supported audio codecs, MP3 continues to dominate the digital audio landscape.

AAC: Advancing Audio Quality

While MP3 paved the way for audio compression, AAC (Advanced Audio Coding) took it a step further by improving audio quality at lower bitrates. Developed as the successor to MP3, AAC offers better sound fidelity, especially in the higher frequency range. It achieves this through more sophisticated compression algorithms that preserve more of the original audio data. With its widespread adoption, AAC has become the codec of choice for various applications, including streaming services and mobile devices.

Ogg Vorbis: Open Source Audio Compression

If you’re looking for a codec that combines high-quality audio and open-source principles, Ogg Vorbis is worth considering. Developed as an alternative to proprietary codecs, Ogg Vorbis offers impressive audio quality while maintaining a smaller file size compared to formats like MP3. Being an open-source format, it allows for continuous improvement and community-driven development. Ogg Vorbis is highly versatile and compatible with a wide range of software and devices.

“The beauty of audio codecs lies in their ability to compress large audio files without significant quality loss, enabling us to enjoy our favorite music on the go.” – John, an avid music listener.

Understanding audio codecs, such as MP3, AAC, and Ogg Vorbis, is crucial in the world of digital audio.

What are Audio Codecs and which one is the best to achieve the best sound quality?

Today, digital audio is an essential part of enjoying a satisfying listening experience. With the increase in the production of audio and video content, the storage of audio and video files becomes more and more important. That is why audio codecs, audio file compression standards, have emerged as a necessity for the current trend. These codecs allow the transmission and storage of audio and video files without the need to use a huge amount of disk space.

What are Audio Codecs?

Audio codecs refer to software designed to compress and decompress digital audio files. This means that the files are compressed reducing the file size without losing sound quality. This compression becomes possible thanks to codec technology. Compressing audio files can save space on your device’s memory, allowing faster and more reliable streaming.

Advantages of Audio Codecs

There are many reasons why audio codecs are so powerful and popular. Audio codecs offer a number of advantages, such as:

Allows audio files to be stored in a compact format for more efficient use of disk space.
Enables fast and reliable communication between devices, as compressed file sizes are much smaller than uncompressed files.
Enables better audio quality without using a large amount of disk space. Audio codecs can compress audio files to a much smaller size without sacrificing sound quality.
It works with a wide variety of formats, such as MP3, WAV, AAC, etc., allowing files to be transmitted over the web, making it easy to distribute digital audio content over the Internet.</ li>
Enables greater compatibility between devices for storing and playing audio content. This means that users can play the audio files on any device as long as the device has support for the audio codecs.

What Are The Most Used Audio Codecs?

There are several types of audio codecs available for commercial use. The most common codecs are:

MP3 – MP3 is the most popular audio format today. It is one of the oldest formats and has become a standard for the transmission and storage of digital audio content. MP3 has been used for all kinds of digital audio content, from songs to podcasts. MP3 offers acceptable audio quality, although there are other more modern formats with better audio quality.
AAC (Advanced Audio Coding) – AAC is a newer digital audio format. It offers better audio quality than MP3 even though the compressed file size is much larger. AAC has become the preferred audio format for the transmission and storage of digital audio content.
WAV (Waveform Audio File Format) – WAV is an uncompressed audio format that offers excellent audio quality. This means that WAV files are not compressed. These files are ideal for audio editing as they have uncompromised audio quality. However, the size of WAV files is much larger than that of compressed files.

What is the Best Audio Codec?

Each audio format has its own advantages and disadvantages. The best audio codec for your purpose will depend on your needs for storing and streaming audio content. For example, if you want to edit an audio file for use in an audio production project, then the WAV format is the best choice. If you want to stream audio content over the web, then the AAC format is the best option.

What is Mp4Gain and What is its Importance?

Mp4Gain is a software tool used to normalize the volume of audio and video files. This tool allows you to adjust the volume of files so that all files are of the same volume. This is important for audio and video files that are being streamed over the web. With Mp4Gain, users can ensure that audio and video files are played at the same volume for a better listening experience.

THE MOST COMMON FORMATS FOR MUSIC AND OTHER AUDIO FILES, AND HOW THEY ARE RELATED TO EACH OTHER

And for the direct competitors of the universal MP3 format, they can count on a lot today.

Due to continuing inconsistencies in home storage of the WAV format, it was eventually discontinued. But for professional studios, he says, the basics of the job. Especially when recording live vocals or instruments. Just convert the recorded material from WAV to MP3 at the final stage.

music format

However, music can be represented in some other popular formats nowadays. For example, many times (especially the Internet) they use these data types like OGG, AIFF, AMR, etc. But the real competitor of MP3 has become the newest and best audio FLAC etc. Of course, for MP3 you can convert all parameters to the maximum, but the playback quality of FLAC represents much higher. Also, it is a single file and the separation occurs directly on the track due to the player or startup software. In other words, listeners see each track individually, but can switch between playback tracks. For the MP3 format, this also seems possible to merge multiple tracks through it, thus creating a single file. But here it is in this version fast switching between tracks will not be possible (normal fast forward should be used, that’s all).

However, not everything is bad. The fact that music or audiobooks are all popular formats today allows them to be easily converted, even keeping the original parameters of the audio material. Based on this, and for sound processing and conversion and audio editors, almost all programs call converters. Any program of this type (MP3 editor or converter) detects the original and final type of audio files, is unambiguous and can produce direct and reverse transformations. Let’s explain this specific example.

WAVE THEORY AUDIO EDITOR FOR MP3 FILES
Many types of software are used in audio processing today. First, look at the narrow application of so-called audio editors. The most prominent representatives of these can be called giants Sony Audio Forge, Sintrillium Cool Editing Pro, which was later acquired by Adobe and renamed Audition, Acoustica Mixcraft, ACID Pro and many others.

mp3 editor

The principle on which they operate is that, for convenience, all MP3 audio programs have a typical waveform, as originally used for WAV files. This method determines the appearance and opportunity enough to edit any type of conventional audio material in WAV format. Other than that, the fact that you can do basic copy, cut, paste, etc. E., it’s just a matter of getting the frequency characteristics and bitrate changes, not to mention using a lot of extra effects that plug into VSTs via DirectX or a generic host bridge studio thing.

In its simplest form, the conversion can be done using the standard file menu, which contains the line “Save As…” (Save As…) or the export function present in MP3 format. Thus, all the process is reduced to just the final selection of the format (MP3 here as an example) and activation of the recording mode. In this case the conversion will be done automatically saving the current configuration parameters and the frequency characteristics. I don’t like the original version? ?Nothing is easier than changing the format to MP3, pre-specified with higher settings. However, one thing needs to be considered here: if the raw material is of such poor quality that special remediation or even professional tools will not work for audio it is necessary to use Repairs here, the intervention of various filters, etc. D. For the layman, it will cause great difficulties.

As is clear, there is absolutely no difference between the audiobooks we are dealing with: MP3, music or just recorded voice or noise. By the way, audiobooks are supposed to have a much lower sound quality by default. This is understandable, since the file has to take up minimal space and, in general, the perceived sound characteristics of speech are not that important. Finally, is this a professional recording of a particular set of albums?

However, if you use some standard operations, even without specific knowledge, it’s fine to achieve good results, especially since there are such built-in templates, based on any application for specific operations. Of course, it will be very difficult for the first time to achieve a perfect sound, but if you study the plan and understand how it works, it will work like clockwork, and as a result, it will take a lot of time.

What are the digital audio formats?

PCM, Wav, Aiff. Compression. Mp3, Ogg, Wma.

Working with digital audio is almost a chore for puzzle specialists. Since audio is saved on the computer and all computer files have extensions, we have to interpret each acronym and abbreviation.

The extension is the end of the file after the name and period. It is used to know what type of file it is, whether it is a text, a video or an audio. There are many extensions and they are all sure to sound familiar to you: WAV, RM, MP3, WMA, OGG … Let’s play, then, to decipher puzzles and see what each of these acronyms means.

UNCOMPRESSED DIGITAL AUDIO FILES

.PCM

It is not a file type or format, but a technique of transforming analog to digital audio without any compression. (1) Therefore, we do not see audios with the pcm extension. We work with PCM when digitizing, but we always keep files with one of these extensions:

.WAV: (Wave, wave in English)

It is the most widely used uncompressed digital audio format. It belongs to Microsoft / IBM.

.AIFF: (Audio Interchange File Format)

It is similar to WAV but for Apple Macintosh or MAC computers.

.CDA

: These are the audio tracks recorded on Compact Disc that also use the PCM system.

All uncompressed files are large. Approximately 10 megabytes for every minute of audio. These are the formats used to store audio at a professional level since the quality is very good. But when we don’t need that much quality and we’re short on space, it’s time to use file compression.

AUDIO COMPRESSION

Compressing is reducing and whenever we reduce we lose something. The same is true for digital audio. The latest advances have allowed compression to be done with the least possible loss of quality, but there always are. Against that, much has been gained in reducing the size of the files.

While a 4-minute audio in WAV format takes approximately 40 megabytes, that same audio, compressed to MP3, can reduce its weight to 4 megabytes, 10 times less. And apparently, they sound the same. (2)

SAVE WITHOUT COMPRESSING

When working in production, it is always recorded in WAV, without compression. In that same way it is edited and mixed. If the final result of the edition is an audio to be uploaded on the Web or saved on the hard drive of a computer, we can compress it to mp3 but with a quality of no less than 160 kbps.

If, on the contrary, the production has as its final destination to be recorded on a CD, never compress, always leave the audio in WAV and burn it that way on the CD.

1. How does compression work?

It is not about wrinkling or crushing the audio. Most audio compression systems take advantage of a “defect” in our ears to reduce file size. It is called masking.

Masking is a property of the human ear that prevents it from distinguishing two frequencies close together within the same range, one masking the other. For example, if a sound with a frequency of 12 Khz and another of 12.2 Khz sounds at the same time in a song, we could remove one of the two without being noticed when listening to it.

In this way, the compressor “subtracts” the masked frequencies, which reduces the number of bytes. And fewer bytes in computing translates into smaller files, but not shorter. The song, when compressed, lasts as long as it is uncompressed.

2. Quality of compressed files

We saw in the previous question that digital audio has two parameters: the sampling frequency (the optimum is 44.1 Khz.) And the resolution or size of each sample (8 or 16 bits). By compressing, we add a third parameter to these two, the bitrate. It is the amount of kilobytes per second (kbps) and refers to the quality of the compression.

• A lower number of Kbps, more compression, smaller file size, but lower quality.

• A higher number of Kbps, less compression, larger file size and more quality.

A compressed audio at 128 Kbps has a higher compression level than a 256 Kbps one. That means that 128 is a smaller file and less quality than 256. Although you must have a cat’s ear to distinguish between both!

VARIABLE OR CONSTANT BIT

Some files have a constant bit rate per second (CBR Constant Bit Rate) and others have a variable one (VBR Variable Bit Rate). The constant is always the same for all audio, for example 128 kilobytes per second. In the variable method, what the compressor does is use more bits when there are parts of the audio where there are more frequencies and it cannot mask all of them.

COMPRESSED FILE FORMATS

Mp3 (MPEG-1 Audio Layer 3)

It achieves high compressions without much loss, although it all depends on the quality of the compression we use. 128 Kbps and below is not recommended.

Although mp3 is the most widely used compression standard, especially for audio on Web pages, the great drawback is its patent. So any player or editing software that wants to use it has to pay for it.

.OGG (Vorbis)

As a result of this patent, the Xiph.org Foundation developed in 2002 a completely free codec (5) for audio compression. Similar in characteristics to mp3, it is beginning to be used a lot on the Web and in some players since manufacturers do not have to pay the costs of the patent. At this point, it is difficult to completely replace the mp3 but it is eating up a lot of ground.

.AAC (Advanced Audio Coding)

The compression level is higher than mp3 (MPEG-1) without major loss of quality. AAC is one of the codecs used in the new MPEG-4 compression standard. This audio format is used in players like the iPod and in some of the new digital radio systems. AAC is shaping up to be the successor to the mp3.

.RAM (also RM or RA)

They are the files of the Real Network company for audio. The problem is that its reproduction and edition is very limited to software from the same company and few others.

.WMA (Windows Media Audio)

It is Windows’ bet on compressed formats. It is like a WAV, but smaller and less quality. While mp3 and ogg files are played by almost all players and editors, the same is not the case with wma files, so it is rarely used.

. AA3 (ATRAC – Adaptive Transform Acoustic Coding)

Format invented by Sony. It is the one used by minidisc recorder-players.

Most used audio formats

In this article we will talk about the most popular Audio Formats and used for both Music production and Entertainment.

Lossless Audio Formats (lossless)

Also known as Loosless, they are audio formats without loss of sound, its main feature is that it resembles original audio with excellent quality.

Its main disadvantage is the size of the file since when capturing it and converting it into digital audio format, files from 50 to 100 megabytes become depending on the number of minutes and resolution.

Normally it is usually captured with a resolution of 16 bits at 44,100 hertz which is the audio quality handled by a compact disc.

Although today it is usually captured at 48,000, 92,000 and up to 192,000 herts that can vary to 16, 24, 32 and up to 64 bits.

WAV (audio file format)

Undoubtedly this is the best known and most standard format, it was created by Microsoft and is called audio formats without signal loss.

Its main feature is that it closely approximates the capture audio signal, which gives us great sound quality. Therefore it is an audio format widely used for audio editing with Music Production Softwares.

Its main disadvantage is its weight is that 5 minutes of audio is approximately 50 megabytes, which becomes a format that takes up a lot of storage space.

AIFF (audio interchange file format)

This format was created by Apple, it is also an audio format without signal loss.

It closely resembles the original sound at the time of capture but also occupies almost the same space as the Wav.

CDA (audio cd track)

Perhaps you have seen this format before, however it is not exactly an audio format rather it is a shortcut which is part of the audio data of a compact disc. This format is created when you burn a CD with some software such as Nero or Alcohol 120%.

When exploring an original compact disc on your computer you will find these files with that extension.

However, when copying these files to your computer you will not be able to reproduce them since they are only small shortcuts that do not contain the music information, they are only used by stereos, homemade modulars or cars.

In order to have these files you will have to convert this format to one that is readable by your computer, which can be Wav or Aiff or other audio formats with some CDA conversion software to other formats.

FLAC (free losseless audio codec)

This audio format is the most popular since it has no signal loss but with compression, which greatly decreases the file size apart from the fact that it is possible to reverse the compression to have the original version again.

It works very similar to the ZIP file but optimized for audio with the advantage that you don’t have to unzip it in order to listen to it.

Its main disadvantage is the incompatibility to reproduce it in any audio software or mobile devices, therefore you must have installed an application capable of playing it with the appropriate codec.

Audio Formats with Loss (loosy)

Also known as Loosy, they are audio formats with sound losses but with compression as the main feature since these files are reduced considerably such as a Wave or Aiff file could be compressed from 50 to 5 megabytes.

Being compressed by means of some audio compression codec eliminates all irrelevant and imperceptible information for the human ear.

You should practically have a fairly sensitive ear to be able to differentiate losses.

These formats are mainly used for portability in Usb memories, Compact Discs or audio devices such as Ipod, MP3, Cell phones, Tablets, Lap Tops and even Desktop Computers and some car stereos or CD, DVD, Blue Ray players, among others.

MP3 Audio Format

It is the most popular and commercial format used since the 1990s, precisely in 1993 created by the Fraunhofer IIS Institute by Karlheinz Brandenburg.

Its main feature is its low data weight and its compatibility with most audio playback software such as Itunes, Windows Media Player, the extinct Winamp among others.

However, it should be mentioned that this format when compressed eliminates audio information that may be almost inaudible by the human ear.

BITRATE (BIT RATE)

It is practically the one that determines the quality of the MP3 that can be from 8 to a maximum of 320 kbps (kilobytes per second).

It is usually compressed at 128 kbps which is a standard for internet radio, streaming platforms such as Soundcloud or Spotify that usually convert to this quality by default.

At the lowest amount of kbps, streaming is guaranteed to be fluid for most internet connections, but it also loses sound quality.

Although considering this happens to second term since many of the users usually reproduce it with headphones in the street, school, public transport, motorcycles or computer speakers in offices at low volume.

If you are a professional DJ I do not recommend mixing with this format since you will not get the best results in amplified sounds, preferably acquire the versions without loss of signal to strengthen your live presentations.

CBR AND VBR METHODS

The CBR (constant bitrate) method practically converts the audio with the constant dynamic range, while the VBR (bitware variable) method varies its dynamic range.

The advantage of the CBR method is that it converts with greater speed and a lighter audio file is obtained although its disadvantage is that its quality is diminished.

The advantage of the VBR method is that when the audio file is converted, a higher sound quality is obtained since it retains the dynamic range, that is, if your theme has sounds with lower and higher intensity, they will continue to obtain a more dynamic sound.

Another significant advantage is that you can include metadata such as ID3, which you can store information such as the title of the song, the name of the band or artist, year, album and a small image which can be the cover that when reproduced in Itunes or Windows Media Player will be displayed.

AAC format

It is a compression audio format with loss of signal which produces a sound very similar to the original.

The ACC format is an extension of MPEG-2 created by MPEG (moving picture experts group), it is often used for Internet radio broadcasting and by Apple for Ipods with Itunes software, also used by Ahead Nero, Winamp and Nintendo DSi.

Another use is for encoding MP4 videos and recently for the new STEMS audio format created by Native Instruments which is a multitrack format used by DJs.

WMA Audio Format

We cannot ignore the WMA (windows media audio) format that was basically the alternative to MP3.

On this format I will not deepen as it is very little used and incompatible in most mobile devices.

It is only compatible with devices such as Windows Phone, Xbox and Microsoft operating systems. However, if you download a multimedia application for example on your Android phone that supports WMA, then you can listen to it.

The WMA audio format has 3 versions:

WMA Pro: Supports multiple tracks like AC-3
WMA Lossless: Compress with loss of signal
WMA Voice: Aimed at human voices which is used
on Skype and WhatsApp.

AC3 Audio Format

The AC3 audio format also called Dolby Digital which is an alternative to MP3 since it allows the inclusion of multiple audio tracks generally 5.1 for Surround surround audio

What is the difference between MP3 and FLAC

What is the problem with the popular MP3 or why FLAC is of better quality? Actually, in addition to these 2 formats, there are others with different specifications that differentiate them from each other.

In this article we will talk about the most important formats and their characteristics, in this way you can choose the one that suits you.

What is bitrate?

The difference in the size of the files is noticeable

You’ve probably heard this term before, but if you don’t remember it or don’t know what it means, I’ll explain it. Bitrate is translated as the bit rate, that is, the amount of bits or data that are processed in a unit of time. When referring to audio, we usually use the measurement of kilobits per second (Kbps). For example, the music available on iTunes is usually 256 Kbps, which means that there are 256 kilobits of information stored in every second of the song.

The higher the bitrate of a file, the more space it occupies on your hard drive. Usually, a music CD uses a large amount of memory space, so since the early 1990s, researcher Karlheinz Brandenburg developed the audio compression standard we now know as MP3. When an audio file is compressed, the space destined for it is smaller, however, this means that it loses part of its sound quality. For that reason, the different audio formats available are divided into 2 categories: with losses and without losses.

Lossless Formats

Lossless or lossless formats, as they are known in English, retain the sound quality of the original source intact. This means if you compress a CD in any of these formats, your digital music files will have the highest quality.

FLAC. Free Lossless Audio Codec is the most used sound codec, making it one of the best options for storing music without losing quality. Unlike other formats such as WAV and AIFF, the compression it uses decreases the space it occupies. In addition, it is free and free software, so anyone can use it and is compatible with a considerable number of players.
WAV and AIFF. These 2 formats do not use compression, so it could be said that they are exact copies of the original sound source. Although both are of the same quality, what differentiates them is the way they store the data. AIFF was created by Apple, while WAV is used universally. The problem with these formats is that since they do not have any compression, they take up too much memory space. They are normally used in audio editing.
A THE C. Apple’s lossless format is very similar to FLAC because it uses compression, the detail is that it was created by the company founded by Steve Jobs. Although its compression method is not as efficient as that of FLAC (it occupies more space), the advantage is that it is compatible with iTunes and iOS devices.
Formats with losses

Lossy, or lossy, formats are the most common, most systems and players recognize them and compress a lot, which allows large amounts of music to be stored in a small space. One advantage is that if your bitrate is high enough, it will be difficult to distinguish the difference you keep with the original source.

MP3 Its name without abbreviation is MPEG Audio Layer III, and it is the most popular lossy format, so much that it has become the benchmark in the category of digital or downloadable music on the Internet. Although it is not the most efficient format of all, it is the one with the highest compatibility, so it is the first option to choose between lossy formats.
AAC Advance Audio Coding is similar to MP3, although a bit more efficient in compression, which means that your files take up less space while matching the quality of the MP3. Although not as popular, it has the advantage that Apple players support it.
WMA As the name implies, Windows Media Audio is the proprietary format of Microsoft. It is very similar to the 2 previous formats and does not really offer any advantage over them. The disadvantage is that it is not so popular, so it is not compatible with many systems.

Which one should you use?

After having reviewed the main formats of both categories and their characteristics, we conclude that the type of file to use will depend on the habits and tastes of the user. In general, MP3 and AAC are widely recommended, because they are compatible with most players and the quality of both becomes quite good if it is encoded with a high enough bitrate (192 Kbps onwards). If your demands in audio quality are not the highest, any of these 2 formats is ideal thanks to the little space they occupy.

Storing your music collection in FLAC will require many GB of storage

However, storing music for posterity in MP3 or AAC may not be the best idea, since converting from one format with losses to another with losses will produce files with much lower quality. On the other hand, FLAC is the best for preserving music for the future, because it will keep the quality intact and allow converting to other formats in the future, in addition to occupying less space than WAV or AIFF.

If your interest is to enter the world of audiophilia, without a doubt lossless formats are the option. Thus, it is necessary to consider that to notice the difference between a high quality MP3 file and a FLAC, you must have high fidelity headphones or speakers and have a trained ear. Of course, the storage issue is also important, the amount of gigabytes or terabytes you will need to store all your music will depend on the size of your collection.

In conclusion, the format you intend to use will depend on your musical demands, both in quantity of music and in its quality. You just have to remember that the important factors are compatibility and avoid converting between 2 formats with loss and, above all, enjoy music in the way you like best.

WHAT IS THE BEST FORMAT TO LISTEN TO MUSIC?

There are many, but after trying almost all of them, here we tell you which is our preference for quality and file size.

As part of our new discovery, we want to share what our experience has been in the vast market of formats offered in digitalized music. The not so common OGG used by Spotify; the AAC incorporated by Apple Music and even the MP3 used by the Google Play Music and Amazon Music service. They all offer different qualities so you will undoubtedly notice a difference when listening to your favorite songs.

We could even include uncompressed formats such as FLAC, AIFF, or even DSD and WAV. Apparently superior qualities, since, if you are like us who do not have a specialized audio equipment for this purpose, it does not make much sense to bring a file of more than 50 MB on your sixth generation iPod with a capacity of 64Gb.

Removing that from the medium, this article we want to dedicate it exclusively to compressed formats in order to show the benefits and benefits of knowing how to choose the best of all. It is important because, taking it into account, it can also help you solve the dilemma of which streaming music service would suit you best.

3. MP3 (MPEG-1 Audio Layer III or MPEG-2 Audio Layer III)

Mp3 Starting with the most common of all, the MP3, a format that although we can give it the merit of being the first to emerge to digitize the music, it is not so in terms of quality. It is also true that its size makes it the best for allowing a song of five minutes occupying about 10 Mb on average of your internal memory of the cell phone and / or music player. However, its coding and the way in which it cuts digital information to be able to offer a small weight file is one of its clearest disadvantages.

In practice, this is reflected when you put a song like Angel de Massive Attack, where the bass is deep and in detail – that is, you have the “boom” caused by the lower frequencies, in addition to the pick of the strings of the low- you don’t enjoy generating artifacts that distort the signal.

For that reason, the MP3, German format founded with the idea of offering music in the first digital era of computers, is not the best there is in the market … By the way, not long ago it was announced that its creators declared it dead.

2. OGG Vorbis

Ogg was like the direct competition in its time, of MP3. Created by a programmer and vocational musician from the United States named Chris Montgomery, it is clear evidence that when your passion is combined with your work, the results are extraordinary.

Recalling a little the history of OGG to contextualize, it emerges in the nineties as a need to find a better way to encode and compress digitized information. And maybe that is one of the reasons why Spotify chooses this format to play and stream the music: friendly, versatile and small in size, it is definitely better than MP3.

The quality of the same role we mentioned earlier is far exceeded. Not only the bass frequencies sound better defined, but the media and the treble ones are balanced a little – so to speak – to offer better sharpness and detail of the instrumentation in general.

However, it is not the best there is in the market, since besides it is difficult to achieve, there is something that is lacking to be our first choice: we would say that, it is something like the “tone” of the sound.

1. AAC (Advanced Audio Coding)

aac is our first choice. With a sound coding that allows you to eliminate less information from an analog signal, the result is quite noticeable when you compare a song with this extension, with that of the other two formats. The bass sounds completely deep and defined without distorting anything, in addition to the medium and treble being highlighted allowing a wider dynamic range than the MP3 and OGG.

It is the holy grail of compressed music formats. We would even dare to say that the AAC offered by the iTunes Store and Apple Music is as good in quality as a FLAC or WAV. If you put one followed by the other, the only notable difference you can find is the amount of the volume. While an uncompressed format offers you more sound, that other format invented by the Fraunhofer Institute in conjunction with Sony, Dolby and AT&T, has slightly less volume, but with the same quality.

So, the AAC is the best format you can get: it has a fairly small file size; it has a “tone” of music that enhances all the details of the instrumentation and voice in the songs; and having even specializations by sound engineers at Apple to include in their record materials their “Masterized for iTunes” versions, there is no way to make a mistake when choosing it as our favorite.
