About these formats

Audio

What is a WAV file?

WAV stores uncompressed PCM audio, so it is a bit-exact record of the waveform with no encoding loss at all. That makes it the standard working format for recording and editing, and a poor choice for distribution: roughly 10 MB per minute of CD-quality stereo.
