Sound as well as the image is a fundamental piece in an audiovisual production.
If you had to choose between these two extreme situations with which one you would stay.

A good image resolution, but with a sound of poor quality.
Poor image quality, but with a clear and defined sound.
The ideal is to have a good balance of quality between image and sound.
An audio format is a multimedia container that saves data an audio file.
Each of these has its own characteristics and capabilities to be able to be reproduced in one or another system.
They have a series of properties that greatly influence the quality of the file, including the speed or frequency of sampling and the bit depth of information.
AUDIO FORMATS ACCORDING TO ITS QUALITY
The best way to classify the large number of audio formats that exist, is depending on whether they have quality loss or not when compared to the original source of Sound.
Depending on this, we have:
Audio files without loss of compressed and uncompressed.
Files with loss of quality.
UNCOMPRESSED AUDIO FORMATS
These files contain the audio in the highest original recording quality even when it is processed and stored on a computer.
The main drawback is that they are relatively large, which means storing less audio files on a hard drive.
Two examples of uncompressed formats are WAV and AIFF.
The .WAV (Waveform Audio File Format) property of IBM and Microsoft is relatively similar to the AIFF (Audio Interchange File Format) co-developed by Apple Inc.
Both formats can be used in both operating systems.
They are very similar, the difference is that AIFF files allow metadata to be stored inside, that is, additional information such as:
Artist name.
Cover of the disk.
Copyright.
Different notes.
Not being compressed, they take up too much space, but without a doubt to edit the sound is the most successful option.
AUDIO FORMATS COMPRESSED WITHOUT LOSS
These types of formats achieve thanks to a series of algorithms smaller files without losing quality.
HOW CAN THEY COMPRESS WITHOUT LOSING QUALITY?
Uncompressed formats encode both the sound of a recording and the silences, a few seconds of sound from an audio file will weigh the same as the same seconds of silence.
These types of formats compress the file making the silence occupy almost no size.
Among these formats we have the FLAC (Free Lossless Audio Codec) which is the most popular, created by Windows, the ALAC (Apple Lossless Audio Codec) that was created by Apple Inc. and the APE format of Monkey’s Audio.
The three formats are very similar, the fundamental difference will be in its compatibility with the different players.
The FLAC file is the most popular because it is compatible with Windows and macOS, the ALAC created by Apple Inc is very exclusive and practically only works if we play it on iTunes.
Finally, the APE, a format only available in Windows that manages to compress more than the FLAC and the ALAC, but has the disadvantage that it is only compatible with a small number of players.
AUDIO FORMATS COMPRESSED WITH LOSS
Finally, we have compressed formats with loss of quality where you get a file that occupies less space by discarding some frequencies in the sound, usually parts of the audio that are inaudible to the human ear.
Among these formats we have the popular MP3, AAC, OGG and MP2 among others.
The MP3 file (MPEG Audio Layer III) is the standard format for sharing music on the network and the most popular of all since it is compatible with virtually all music players, making this the first option to choose between sounds at a loss.
AAC (Advanced Audio Coding) is similar to MP3, although a little more efficient, which means that files take up less space and have the same sound quality as MP3. It is a format widely used in iTunes and YouTube.
OGG (Vorbis) is a very popular open source compressed format in the spotify music application.
The MP2 is still used especially in radio and television transmissions, but it can be said that in other areas it has already been completely replaced by the MP3 that achieves greater compression with the same quality.
