What is WAV?
Waveform Audio File Format
IBM and Microsoft
WAV is short for Waveform Audio File Format, which was created in 1991. Both Windows and Mac systems have native support for WAVs, so you won’t have any issues with how to open and play them. Files in the WAV format can contain compressed or uncompressed audio, but usually, they come without compression, so WAV files can be quite large. Uncompressed WAVs are useful for professionals who require the best sound playback quality.
The specification of the WAV file type is based on the RIFF specification. Both formats are containers for audio and store data in tagged “chunks.” Every “chunk” (or block) holds information about a part of a file, and, when creating a WAV, you can even leave some blocks empty to ease future sound editing. As for audio encoding, you can compress a .wav file with the MP3 or AAC codec, but WAV is mostly used for storing uncompressed audio.
