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.

Advantages and disadvantages of the main formats

Formats

The MP4 file format

The MP4 file format has long been one of the most popular video formats on the web. Thanks to good compression coupled with good video file quality, excellent compromises can be achieved. The codecs used for MP4 are mainly H.264 or H.265.

Advantage

The format offers a good compromise between image quality and compression and is particularly compelling due to the simple ability to bundle multiple audio tracks and additional elements into a single format.

Disadvantages

MP4 files are often heavily compressed using standard codecs, making processing and creation difficult.

The AVI file format

The abbreviation AVI stands for Audio Video Interleave and means that in this format the video and audio tracks are directly linked to each other. The format is widespread, but technically obsolete.

Advantage

This format is mainly characterized by a very high level of acceptance. There is hardly any player and hardly any browser that does not support AVI files.

Disadvantages

The technical limitations of the file format and, above all, the lack of ability to use multiple audio tracks mean that fewer and fewer users are using the AVI file format.

The MKV file format

The MKV format is currently one of the most popular video formats on the net. It is a powerful container format that can integrate not only video files but also audio tracks, menus, and many other functions.

Advantage

The MKV format is particularly compelling due to the high quality of video files and the wide range of functions in which the format can be used. The format can only be used with the appropriate codec, but it is freely available on the net.

Disadvantages

The disadvantages of the format are mainly the low compression properties, so it is not possible to create very compact files.

The MOV file format

This video format was developed by Apple and is designed primarily for use with Quicktime. However, the format is no longer up to date and is therefore rarely used for network applications.

Advantage

The advantages of the format are mainly the ease of use in an Apple environment and the very high compression, which allows to obtain small files.

Disadvantages

Due to the very high compression of video files, there is a consequent loss of images and information. While relatively small and compact files can be created, in most cases the result is not as convincing.

The OGG file format

The OGG video file format was developed, among other things, to bring more flexibility to the market structure, which is often controlled by the rights holders. The OGG format was one of the first formats to be used in a widespread environment such as Linux, and thus it was able to establish itself in the market very quickly.

Advantage

The OGG file format has the advantage of being very widespread and not having authorization keys. Therefore, most browsers can extract it and use it natively. As a result, this video file format is often used to embed video files on your website.

Disadvantages

Despite the wide distribution, there are also downsides. Both the Safari browser and the older Internet Explorer only partially support the format, which can lead to display issues.

The VOB file format

The VOB video file format was established relatively early as the standard for DVD and was therefore developed primarily for these media. The format is not suitable for network use due to lack of licenses and low compression.

Advantage

The format can be easily read by any DVD player and also offers the advantage of low compression. It also allows you to merge different audio tracks.

Disadvantages

The VOB format is not suitable for network use as it cannot be uploaded on various platforms or on your own website. To play the format, you need your own codec, which is not freely available.

The WMV file format

The WMV format was developed by Microsoft and is still widely used today. Since this format supports digital rights management (DRM), it is generally used whenever the copyright of the video file is required.

Advantage

The format is recognized as reliable on all common devices with the Microsoft operating system and can be used without problems.

Disadvantages

As the format is older, very large video files are only partially supported. There are also limitations on file size and video quality.

What audio and video formats exist?

When we talk about the quality of videos or audio, many doubts arise in people’s minds, as there are many terms that are very confusing for the user. For example, people talk about kbs, people talk about bitrate, the sample rate and many other terms that are not clear in people’s mentality are mentioned.

But in the end the question is always the same, what is it that is truly decisive to have a better video quality or better audio quality? The answer can be simple if we summarize it: because the difference in quality will depend on the amount of information that is stored, because the more we will have more detail.

When we talk about video formats within the different types that are applied to digital video and that there are three important parts to distinguish in them on the Internet or on a DVD:

The video and its codec (When the video is so heavy, it must always be encoded and subsequently decoded). They are simply mathematical algorithms to compress and decompress the video file.
The audio and its different formats or containers.
The file that contains the audio and video. The container
Let’s see which are the most popular and try to explain them:

Digital Video Formats

MPEG: Moving Pictures Expert Group (Mpeg1, Mpeg2, Mp4 or Mpeg4)
AVI: It is the standard format but the one with the most weight. (Xvid or Divx)
WINDOWS MEDIA: Format developed by Microsoft. (. Mp4 or .asf)
MOV: Format developed by Apple. Quicktime needed to read it. Low weight.Ideal for Web (.m4v or .mov)
FLV: Adobe Flash format. Use Sorensen Spark codec. (.flv)
Digital Audio Formats

Mp3 or MPEG-1 Audio Layer 3: Tablet with imperceptible signal loss for humans. (1Mb / Min)
Aiff: Audio Interchange File Format. It has no compression and uses PCM modulation so they are very heavy (10 Mb / Min.)
AAC: Advanced Audio Coding. Mpeg-2 compression. Suitable for surround or surround sounds
Windows Media Audio: The worst quality of all the above, is the Windows format.
Formats of Digital Audio and Video Containers

.mp4
.mov
.avi
.mkv
.flv
.swf
.m4v
The truth is that it is a world and more when the big companies live thinking only of leading their own markets and not from the point of view of the user they have had abandoned for years. Obviously these are not all there are but if I wanted to include the best known.

But if we are talking about a file or files that any DVD or download from the Internet can have in any format or container type Mp4, mkv, avi with greater quality, we must remember that the important thing is the amount of information that they carry inside, it is say the Mbs to which this video is exported.

It is as if we have a 16-ton truck and we put a box of oranges inside when it can carry 1000 boxes of oranges. What we are going to see is oranges but with a very low quality.

I hope I have shed some light on this world of digital video and how the next time you face a file of this type you will be able to understand what each of the things that are attached to it means. I must admit that it is not easy but that with that global vision and knowing what each one means you feel better when facing him.

And you know some kind of format that you are using and do you think it is missing here? This is a live article to be developed among all and thus clarify all more.

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

Why are there so many audio formats and video formats?

People wonder what the reason is, and why there are so many different audio formats and so many different video formats.
This whole issue of audio formats and video formats seems a great confusion. Most users are not very clear because there are so many possibilities, or which are better for their needs.
In general they are guided by what some people tell them, without actually understanding in depth about the subject, but they are simply guided by some reading, by a video from your YouTube, by someone’s comment, and so on.

What are audio formats or video formats?

The easiest way to explain it would be to say that the sound in raw form, without any kind of compression saves a lot of information so it occupies a large amount of space and also the use of the computer cpu when playing it. If you do a detailed analysis, you will realize that some of this raw data does not need to be saved either because they are redundant, because they are inaudible, etc.

Therefore a large number of organizations and companies have decided to create their codecs to be able to compress and decompress the audio and video. Precisely the term codec comes from CODify and DECodify. That is to say, each one of these organizations or companies creates its own method to encode or compress the audio or video and at the same time has a decoder to be able to listen or watch the audio or video.

Obviously each of these codex have been implemented following different paradigms, looking for different objectives, having different objectives. For example, for some codecs, compression has been the priority, that is, saving space, while others have sought to save space, but without losing quality or details in the audio or video.

Each of these codecs produces different files that can only be encoded and decoded by the specific codec of that organization or that company, this causes that file to have a different name. From there we understand that there is a great variety of options and not always one is better than the others but it depends on what we are looking for. Which of the options will work better for us. It is not the same what is appropriate for a person who wants to play music on a computer with a high quality audio card and who will use high quality speakers, which will be very different from what is appropriate for a person what will Listen to the music using a small smartphone that perhaps has low quality speakers. Therefore, it would be unnecessary to store the music in a format that will take up more space but maintain a quality that the phone is not able to play. The same applies to any device that is capable of playing music or video files, you should always use that format that saves the files in a quality that is what the device can play. That way we avoid saving poor files that have a lower quality than our device could have played, or on the contrary save files that have too much information and quality that cannot be played by the device we are going to use.

Then we will understand that those people, often extremists and their opinions about audio and video, who ensure that an audio or video format should always be used, may be exaggerating and their recommendation may not be the most optimal. Most likely, we will have to see where we are going to play that audio and depending on the Audio Response Range and the video response range it is what we end up indicating which is the most appropriate format for our need.

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.
