An audio file saved in the WAV format, a shared digital audio file format used to store waveform data, is known as a WAV file. WAV files frequently store audio recordings in the 44.1 kHz, 16-bit stereo format, considered the typical CD audio format. However, WAV files may contain audio recordings with different sampling rates and bitrates.
The Resource Interchange File Format, also known as (RIFF), a file container primarily used to store video and sound, is the foundation of the WAVE format. Microsoft and IBM jointly created the WAVE format in the early 1990s, and Microsoft Windows now uses WAV files as the primary method for storing uncompressed, unprocessed audio.
