AUDIO FILE EXTENSIONS  What are they and types? ▷ 2020

Gone are the CDs, their music devices and, in fact, even the radio. Now digital is taken in all aspects and in its most current version and we listen to everything through files, data or tracks that include sound content that we can reproduce with different programs and appliances.

Part of these is the audio file extension, which Is that which indicates the type of track which is the one in front of us. Of course, we also have other elements, although the one that interests us and which we will talk about next is precisely that.

We advise you to save this post in bookmarks because It will come in handy when it comes to identifying the audios that you download and knowing how to play them. We are going to show you, therefore, what these formats are, why and what they are used for and where and how you can reproduce the audios that they accompany.

What is the extension or format of an audio file and what is it really used for?

what is AUDIO file extension

The format of a file will tell us how it is built, what its characteristics are and what software or program we can run it with. In the case of the audio file extension, what it is going to tell us, in effect, are the characteristics that this soundtrack has.

Each extension assumes a type of quality, compression, program and codecs necessary for interpretation and reproduction, etc. Everybody file types audio consists of a name. The extension would be the alphanumeric group that we find accompanied by a period after said name.

For example, the track “NoMeAcuerdo.mp3”:

It tells us that this song is called “I don’t remember” (“I don’t remember”) and that the extension it has is of type “.mp3”, that is, its characteristics are those necessary for mp3 players can reproduce them.

It is worth mentioning that so that they can achieve it, both they and the files must have codecs, which are small elements that are responsible for encoding and decoding information and who act as interpreters.

The codecs are found in each song or track and correspond to one type of extension or another (also called format). The player of audio that we want to use has to work with those same codecs, so that there is an interaction between the two and the information contained in the file in question can be deciphered.

It should be noted, although we have already said it, that only by knowing the format of a track we can get an idea of ​​its quality. In this regard, there are two essential concepts.

  • Sample rate: A sample is a piece or sample. Audio software uses these to play the tracks efficiently. The rate is simply the number of samples that are played in each second of recording. Obviously, the greater the quantity, the more elements working in the same track instant and, therefore, the more details that are obtained (or maintained).
  • Bit Depth: Bit depth is, in turn, the information found within each sample. This is similar to what we find in the image sector, obtaining, therefore, that more bits represent more information in each sample.

Types of audio file extensions and formats and their associated programs for playing them

Of course, we will end by telling you what are the characteristics of the most used audio extensions, we will name the rest so that you do not lose sight of them and, obviously, we will tell you where you will be able to reproduce each one of them.
