10 Common Audio Formats: Which Format Should I Choose?

Audio files come in various formats and sizes, in addition to our common MP3, there are AAC, FLAC, OGG, WMA, etc.

Why are there so many different audio standards? What format is the best? What should you choose when saving audio files?

In fact, all audio formats can be divided into 3 categories, and once you understand the characteristics of each of these 3 types, you can choose one of the three, and then choose a further subdivided category according to your specific needs.

Comparison of audio formats – operation, equipment – Introduction to 10 common audio formats: which format should I choose?
uncompressed audio format
The uncompressed format preserves the original audio waveform. The so-called original audio waveform refers to the result after the sound is captured and converted to a digital signal for storage. Raw audio waveforms are stored without any post processing. From the results, such an audio file will consume a lot of space. For 24-bit (24-bit) 96 KHz audio, you need about 34 MB of storage space per minute.

Uncompressed audio format: PCM
PCM is short for Pulse-Code Modulation, which is a technical method of simulating sound using digital signals. The sounds that we can hear in nature exist in the form of physical sound waves, and in order to simulate this sound wave with a digital signal, scientists decided to sample it and record it with another wave, which is what we call a pulse.

Therefore, digital audio has two basic concepts: sample rate and bit depth. The so-called sampling rate refers to the speed of how many times the sound is sampled. The so-called bit depth refers to the space occupied by a single sample. In uncompressed formats, the product of the sample rate, bit depth, and audio duration is the space occupied by the digital signal that represents the audio content.

PCM is a format commonly used on CDs and DVDs, but its derivative LPCM is often used in practice. LPCM is short for Linear PCM, which is Linear Pulse Code Modulation. Most PCM files in use today are actually LPCM files, so there is no need to differentiate between them.

Uncompressed audio format: WAV
WAV is short for Waveform Audio File Format, which is a standard audio format developed by Microsoft and IBM in 1991.

Many people think that WAV is an uncompressed audio format, but this is not entirely true. In fact, WAV is a “wrapper” type format, a common format developed by Microsoft to use audio for various platforms. So it is possible for WAV to contain compressed audio, but this is rarely the format of choice when using compression these days.

What are the common audio formats?

Most frequent and popular sound formats

05 AAC format

AAC is actually short for Advanced Audio Coding. The algorithm adopted by AAC is different from that of MP3. AAC improves encoding efficiency by combining other features. The AAC audio algorithm far surpasses some previous compression algorithms (such as MP3, etc.) in terms of compression capabilities. In conclusion, AAC can provide better sound quality with 30% smaller file size than MP3 files.

It is one of the best lossy formats out there. There are multiple encodings, with bit rates up to 448 kbps. In terms of hardware support, advanced mobile phones and mp3 players are now generally supported.

06 VQF format

The VQF format is an audio compression technology jointly developed by YAMAHA and NTT. Its compression ratio can reach 1:18. Therefore, under the same circumstances, the compressed VQF file size is 30%-50% smaller than MP3, which is more suitable for online streaming, while the sound quality is excellent, near to CD quality (16-bit, 44.1 kHz stereo). But VQF has not revealed the technical standards, so far it has not become popular.

07 FLAC format

FLAC is short for Free Lossless Audio Codec, which can be interpreted as Chinese lossless audio compression coding, which is characterized by lossless compression. Unlike other lossy compression codes like MP3 and AAC, it can restore the sound quality of music discs. It is now compatible with many software and hardware audio products.
It can be said that FLAC is similar to MP3, but it is losslessly compressed, which means that the audio is compressed in FLAC without losing any information. And you can use the player to play compressed FLAC files, just like playing MP3 files.

08 APE format

APE is one of the most popular digital music file formats. Unlike lossy compression methods like MP3, APE is a lossless audio compression technology, which means that after compressing the audio data file read from the audio CD in APE format, you can also compress the file in APE format. The audio file is exactly the same as before compression, without any loss.

The file size of APE is about half that of CD, which is loved by many music lovers, especially for friends who want to stream audio CDs over the network, APE can help them save a lot of resources.

What are the common audio formats?

Most frequent and popular sound formats

01 MP3 format

MP3 is one of the most common audio formats. Its full name is Moving Picture Experts Group Audio Layer III. Simply put, MP3 is an audio compression technology that uses MPEG Audio Layer 3 technology to compress music into a smaller capacity file with a compression ratio of 1:10 or even 1:12. Compress files to a lesser extent in small cases. And it keeps the original sound quality very well.

It is precisely because of MP3’s small size and high sound quality that the MP3 format has become almost synonymous with online music. Use an MP3 player to uncompress (decode) MP3 files in real time so that high-quality MP3 music can be played. The highest bitrate is 320K, and the high-frequency part is one size fits all, which is its default.

02 WMA format

The full name of WMA is Windows Media Audio, which is an audio format promoted by Microsoft. The WMA format achieves a higher compression ratio by reducing the data stream while maintaining sound quality. The compression ratio can usually reach 1:18, and the generated file size is only half of the corresponding MP3 file. In addition, WMA can also be added to prevent copying through the DRM scheme, or add restrictions on playback time and playback times, and even restrictions on playback machines, which can effectively prevent piracy.

03 WAV format

WAV format is a lossless sound format developed by Microsoft Corporation, also known as waveform sound file. It is the oldest digital audio format and is widely supported by the Windows platform and its applications. The WAV format supports many compression algorithms, supports a variety of audio bits, sample rates, and channels. It adopts 44.1kHz 16-bit sampling rate. Therefore, the sound quality of WAV is almost the same as that of CD, and it is suitable for uploading to all major music platforms. But the WAV format is bulky and difficult to spread.

04 ASF format

The full name of ASF is Advanced Streaming Format, which is a media playback format developed by Microsoft and is suitable for playback on the Internet.

All the Audio Format Differences: Which One Should You Use?

Three classifications of audio formats

Characteristics and differences of different audio formats

Which audio format is right for you?

You already know MP3, but what about AAC, FLAC, OGG or WMA? Why are there so many audio file formats and is there any best audio format?

Comparison of audio formats

Audio files come in various types and sizes. While we’re all probably familiar with MP3, what about AAC, FLAC, OGG, or WMA? Why are there so many audio standards? Is there a better audio format? Which ones are important and which ones can be ignored?

All audio formats are divided into three main categories, and once you know what the categories mean, you can choose the format within the categories that best suits your needs.

uncompressed audio format

Uncompressed audio consists of actual sound waves that have been captured and converted to digital format without any additional processing. So uncompressed audio files tend to be the most accurate, but take up a lot of disk space: about 34MB per minute for 24-bit 96KHz stereo.

Audio file format: PCM

PCM stands for Pulse Code Modulation, a digital representation of the original analog audio signal. Analog sounds exist as waveforms. To convert a waveform into digital bits, the sound must be sampled and recorded at specific intervals (or pulses).

This digital audio format has a “sample rate” (how often the samples are made) and a “bit depth” (how many bits are used to represent each sample). There is no compression involved. Digital recordings are almost accurate representations of analog sounds.

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.

Understanding digital audio formats

When it comes to digitally distributing our music it is important that we understand what they are
the different formats, which are the most used and which are the best in terms of the
Relationship between size and quality.

PCM digital audio

WAVE

The name comes from the acronym waveform audio file format and is a used file
usually on computers with the Windows operating system.
WAV or WAVE files contain audio in LPCM format (Linear Pulse Code
Modulation) This is a way to encode an analog audio signal to the domain
digital by using equidistant samples over time of amplitude values
of the analog signal.
The quantity of samples is given by the sampling rate or sampling rate,
while the amount of possible amplitude values is determined by the
Bit depth or bit rate.
The sampling frequency of the CDAUDIO for example is 44.1 kHz and 16 bits. exist
higher sampling rates such as 48 kHz, 88.2 kHz, 96 kHz up to 192 kHz at
this system.
On the other hand, WAV files are uncompressed audio and are generally used in
stages of recording, editing, mixing and mastering for being of high quality.
The higher the sample rate and the greater the number of bits, the file size will be
our hard drive
In general for professional uses at least a frequency of
44.1 kHz sampling and a depth of 24 bits preferably.
The standard extension for this type of file is: .wav

AIFF

The name comes from Audio Interchange File Format or audio file format
interchangeable, this format was developed by Apple computers and is used to save
and manipulate audio on computers.
It is like WAV a file type without compression or lossles therefore allows
Processing for professional applications such as recording, editing, mixing and
mastering as well as for professional video uses.
Another similarity with WAV files is that it is PCM audio (press code
modulation) that for practical purposes it is the same as the LPCM.
The standard extension for this type of files is .aiff

MP3

Also known as MPEG1 or MPEG2 audio layer, it is a form of coding
of digital audio in which psychoacoustic models discard information from
Audio that is presumed is not audible to most users.
As an example a file created with a resolution of 128 kbits / s is equivalent to 1/11
the size of a file on an audio CD.
The main purpose of using this type of coding is to reduce the size of the
files and be able to send / download faster, especially through
from Internet.
Being a file type reduced in quality IS NOT RECOMMENDED for
recordings, editing, mixing or mastering of professional audio.
For this reason we recommend NOT to use it to send us your clues to
mix / master

What is the best audio format for listening to music?

Although the MP3 format is the most popular of all available audio formats, it is not the only one, some such as FLAC, WMA, OGG and others, have features that, depending on what you want, can be very useful in certain occasions

Here I show you a summary of what to expect when you are looking for the best audio format to listen to music.

As a general rule, we can classify audio formats into two categories: those that retain all quality and those that lead to loss of quality in sound or information.

Those who retain all audio quality come from pure sources such as CDs, while those who lose quality sacrifice this information to save space.

Formats that preserve audio quality:

FLAC: Free Lossless Audio Codec or FLAC, for its acronym in English, is one of the formats that best preserves audio quality. Its compression algorithm is excellent and does not generate quality losses, it is open source and the file size when compressed is much smaller
Apple Lossless: known as ALAC is very similar to FLAC, but not as efficient as this, so these files are larger, although they have the unconditional support of iOS, which FLAC does not have

APE: The problem with this format is that it is not very compatible with the vast majority of players, but it is similar to the FLAC or ALAC format in terms of audio quality. Being very compressed makes the computer’s processor work faster so it is not recommended in low power computing equipment
WAV and AIFF: they are not compression formats, but exact copies of the original content, differing in the way they save the data. While AIFF was created by Apple, WAV is more universal, but both take too much disk space.

Formats with loss of audio quality:

MP3: MPEG Audio Layer III or MP3, as we all know them, is the most common format you can find
ACC: is more efficient than MP3, files in this format are smaller and is very popular on iTunes
OGG Vorbis: it is a free and open source alternative to MP3 and ACC, it is not restricted by patents but not supported by many players
WMA: this is the proprietary format of Microsoft very similar to MP3, without great advantages over the others
Which audio format to choose
You may be interested: «It’s proven: classical music modifies your genes and makes you smarter»
It is more recommended to choose MP3 or AAC, since many players support them, in addition, if they are encoded with a high bitrate they are almost indistinguishable from the original source. However, if what you want is to burn your music, I recommend formats like FLAC, then you can convert everything to other formats without losing audio quality.

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.
