For example, advances in machine learning and artificial intelligence are making it possible to create more realistic and lifelike sounds. As stated in the book “The Sonic Boom: How Sound Transforms the Way We Think, Feel, and Buy,” “The next stage of audio is likely to involve more complex soundscapes that are tailored to the specific needs and preferences of each listener.” This personalized approach to audio will create a more immersive and enjoyable listening experience for all.
Final Words:
As the world of audio continues to evolve, it is exciting to see what the future holds. From emerging formats to new trends and innovative technologies, the possibilities are endless. Whether you’re a music lover, a podcast enthusiast, or simply enjoy listening to audio content, there has never been a more exciting time to be a part of the audio industry.

Digital Audio File Formats: Everything You Need to Know

Digital audio file formats have become ubiquitous in the modern era of music and sound. They allow for easy storage, distribution, and manipulation of audio data. However, with so many different formats available, it can be challenging to know which one to use for a particular purpose. This article aims to provide a comprehensive guide to digital audio file formats, explaining what they are, how they work, and which ones are best suited for different use cases.

What Are Digital Audio File Formats?

Digital audio file formats are a type of computer file that contains digital audio data. They are used to store, distribute, and manipulate audio data in a variety of contexts, such as music production, broadcasting, and online streaming. Audio data is typically recorded and stored in an analog format, such as magnetic tape or vinyl records. Digital audio file formats allow this data to be converted into a digital format, which can be stored and manipulated using computers and digital audio software.

There are many different digital audio file formats available, each with its own characteristics and intended uses. Some of the most common formats include:

MP3
WAV
AIFF
FLAC
ALAC
AAC

How Do Digital Audio File Formats Work?

Digital audio file formats work by converting analog audio data into a digital format. This involves sampling the audio data at regular intervals and converting each sample into a binary code that can be stored on a computer. The most common way of doing this is to use pulse-code modulation (PCM), which involves measuring the amplitude of the audio signal at regular intervals and converting it into a binary code.

Once the audio data has been converted into a digital format, it can be stored on a computer in a digital audio file format. Different formats use different encoding schemes to compress the audio data and reduce the file size. Some formats, such as MP3, use lossy compression, which means that some of the audio data is lost during the compression process. Other formats, such as FLAC, use lossless compression, which means that all of the audio data is retained during compression.

Which Digital Audio File Format Should You Use?

The choice of digital audio file format depends on a variety of factors, such as the intended use of the audio data, the desired sound quality, and the available storage space. Some of the most common use cases and the recommended file formats for each are:

Music Production

When producing music, it is essential to use a high-quality, uncompressed audio format to ensure that the final mix sounds as good as possible. The recommended format for music production is WAV or AIFF, which are both uncompressed, lossless formats that retain all of the audio data.

Online Streaming

For online streaming, it is important to use a format that can be streamed easily over the internet without using too much bandwidth. The recommended format for online streaming is MP3, which uses lossy compression to reduce the file size while retaining a high level of sound quality.

High-Resolution Audio

For high-resolution audio, it is important to use a format that can retain all of the audio data without introducing any compression artifacts. The recommended formats for high-resolution audio are FLAC and ALAC, which are both lossless, uncompressed formats.

Streaming Audio Formats

Streaming audio formats have become increasingly popular in recent years, with the rise of music streaming services such as Spotify, Apple Music, and Tidal. These services use various audio formats to stream music over the internet.

MP3

MP3 is one of the most popular audio formats for streaming music due to its small file size and good quality. MP3 is a lossy format, which means that it compresses the audio data by discarding some of the information that is deemed less important to the listener. The resulting file size is much smaller than a lossless format such as WAV or FLAC, but there is a tradeoff in audio quality. Most streaming services use MP3 as the default format for streaming music due to its widespread compatibility and low bandwidth requirements.

AAC

AAC stands for Advanced Audio Coding, and it is a lossy audio codec that is widely used for music streaming and downloading. AAC is the default audio codec for Apple devices and is used by popular music streaming services such as Spotify, Tidal, and YouTube. AAC is similar to MP3 in terms of file size and quality, but it is more efficient in its compression algorithm, resulting in better sound quality at the same bitrate. AAC is also capable of supporting higher bitrates than MP3, making it a popular choice for high-quality streaming.

FLAC

FLAC is a lossless, uncompressed audio format that is popular among audiophiles and music enthusiasts due to its high-quality sound and ability to retain all of the original audio data. While FLAC files are much larger than lossy formats such as MP3 and AAC, they offer superior sound quality that is comparable to the original studio recording. FLAC is not commonly used for streaming due to its large file size, but it is popular for downloading high-quality music files.

ALAC

ALAC stands for Apple Lossless Audio Codec, and it is a lossless audio format that is similar to FLAC but is optimized for use with Apple devices. ALAC is compatible with most Apple devices and can be used with iTunes to download and stream high-quality music. ALAC is not as widely supported as FLAC, but it is a popular choice for Apple users who want to retain the original sound quality of their music files.

Conclusion

Digital audio file formats have come a long way since the early days of digital music, with new formats and technologies continually being developed to improve sound quality and file size. Each format has its advantages and disadvantages, and the choice of format will depend on the intended use of the audio file. For streaming music over the internet, lossy formats such as MP3 and AAC are the most commonly used due to their small file size and widespread compatibility. For high-quality audio, lossless formats such as FLAC and ALAC are recommended to retain all of the original audio data without introducing compression artifacts. Ultimately, the choice of format will depend on the listener’s preferences and the intended use of the audio file.

When it comes to adjusting the volume of your digital audio files, one useful tool is mp4gain. Mp4gain is a software tool that allows you to normalize the volume of your audio files to a consistent level, eliminating the need to adjust the volume manually. This can be particularly useful when dealing with files from different sources that may have different volume levels. Mp4gain is easy to use and can help to improve the listening experience of your digital music collection.

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.

Best Audio File Formats

After all, it’s not always clear which format is best for music. Some services, like Amazon, sell digital music in MP3 format. Although Apple offers song downloads from its iTunes Store in AAC format.

Audio File Formats

So the question arises what formats can your device play. If it is relatively new, it can play lossless formats like FLAC, as well as older lossy formats like MP3 and AAC.

And to add even more confusion, there is the listening factor. How important is sound quality to you?

To help you decide, here are some things you can do.

Check the format compatibility of your portable device

Before deciding on an audio format, the first thing to do is check its compatibility. This can usually be found on the manufacturer’s website or in the specifications section of the user manual (if there is one, of course).

If you are not going to use high quality audiophile equipment in the future, then lossy audio may be sufficient if you are only going to use your laptop. For greater compatibility, the MP3 file format is the safest bet. This is an old algorithm, but it works well. In fact, it is still the most compatible audio format for everyone.

However, if you are ripping tracks from a music CD, for example, it would be wise to keep a lossless copy on your computer / external hard drive and lose it for your laptop as well. This will keep your music safe in the future, even if new formats and hardware show up later.

Consider the bit rate

Bitrate is an important factor to know, especially if you are looking for the best quality music playback. However, the actual bit rate setting depends on the audio format you are using.

For example, the MP3 (MPEG-1 Audio Layer III) format has a bit rate range of 32 to 320 kbps. There are also two encoding methods you can choose from: CBR and VBR. In this case, instead of encoding using the default CBR (constant bit rate) encoding, it is much better to use VBR (variable bit rate) encoding. This is because VBR will provide you with the best file size ratio.

The encoding you use is also an important factor.

Digital Audio Formats

Today, there are several dozen formats (codecs) that are used to represent audio files. Among them, there are no more than a dozen running gear.
Save and read later –

MP3, FLAC, ACC, WAV

In the 20th century, we choose between the media and the media to play music. Cassettes, vinyl, CD – each multimedia format had its own player, each had its own advantages and disadvantages. In the 21st century, the focus has changed significantly. Playback tools have become omnivorous and you have to choose not the multimedia format, but the format of the audio file.

At a time when digital music had not yet penetrated the computer as it does now, the choice for connoisseurs of high-quality sound was quite simple and straightforward. The most popular CDs, and those who could afford to buy more expensive equipment and discs, opted for SACD or DVD-Audio players, or universal models that play all optical audio disc formats. Now you can get high-quality audio content without buying discs, in which case the whole choice comes down to the format for storing your music.

Today, there are several dozen formats (codecs) that are used to represent audio files. Among them, there are no more than a dozen running gear. Lossy audio compression is most often done using the MP3 (MPEG-1 Layer3) codec, less often the WMA format, which is a proprietary Microsoft development, is used for this purpose; AAC, developed by Apple or available under the GPL-free Ogg Vorbis format. We will not dwell on the topic of compressed audio in detail, we will limit ourselves to a brief description.

Saehan Information Systems F10 – The world’s first mp3 player appeared in 1998 and cost $ 250
The MP3 format and its aforementioned analogues allow you to compress CD quality music material into smaller files (the compression ratio ranges from 2: 1 to 11: 1). As the developers envisioned, compression algorithms should process the audio stream in such a way that the sound of the compressed file does not differ from the original. In fact, you can hear the difference between the sound of a compressed file and an uncompressed original, and the higher the quality class of the equipment, the more obvious these differences become. There is no difficulty in burning a CD to MP3 or getting ready-to-use MP3 files from the Internet or on physical media.

The only specificity of compression files is the ability to incorporate copy protection or unauthorized playback protection (DRM) into them. One of the main initiators and distributors of the technology to protect audio files was Apple, which, however, very early presented a proposal to abandon such solutions and urged all manufacturers of music products to distribute it without protection. Since 2009, music sold on the iTunes Store is not protected. The vast majority of compressed content sold over the Internet and on physical media is also not protected against unauthorized reproduction.

ITunes interface
There are several different formats to store digital music without losing quality. The lossless and uncompressed audio stream is saved to a WAV or AIFF file. In this case, the file type is determined by the type of operating system on which the audio stream is saved. WAV format is a joint development of Microsoft and IBM, and AIFF is the brainchild of Apple. There are also proprietary lossless audio compression formats: Microsoft’s WMA Loseless (also known as WMA9) and Apple’s ALAC. Of these, only the second has become widespread due to the fact that it is almost the only way to listen to high-quality audio from iOS devices.

Another option for storing uncompressed audio content is disc images, which are a single file with the ISO extension, which is an unmodified copy of the content on a digital medium.

The most widely used lossless music compression format is the FLAC (Free Lossless Audio Codec) format. As its name suggests, this format is distributed under a free license, which means that to ensure its support on any audio device, it is not necessary to pay royalties. FLAC allows you to store audio tracks with up to eight channels and a bit depth of up to 32 bits and a virtually unlimited sample rate, allowing it to be used to store any content, including multi-channel HD soundtracks. The popularity of FLAC as a high quality audio compression codec is as great as the popularity of MP3 among compression audio formats. The vast majority of high-quality music is stored and distributed in the FLAC format.

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.
