A standardized file for storing audio information. Supported by virtually all music players and playable on almost all mobile devices. When the audio data is compressed, the sound quality decreases, albeit insignificantly. The compression process erases the frequency that is imperceivable to the human ear. This format allows you to save storage space. You can store and send the audio files after compression. The MP3 format was developed by the German company Fraunhofer IIS. The user can adjust the compression ratio and the audio file quality.

Waveform Audio File Format: a format for storing digitized sound recordings

The Waveform Audio file format is a creation of Microsoft Corporation. The WAV format is the first standard audio file with high-quality sound. It contains sounds, sound effects, voice recordings, and music tracks. The Waveform Audio file format is currently considered outdated. The main reason for its obsoletion is the fact that files of this type are characterized by a large size. The greatest advantage of WAV is sound compression without any losses. In this format, samples range from 8 to 16 bits. Waveform Audio files are used as system sounds in the Windows operating system.
