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 The Waveform Audio file format is currently considered outdated.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.
