WAV vs. MP3
WAV stores audio uncompressed, as used by recording software, audio interfaces and many voice recorders. That gives perfect quality but huge files – about 10 MB per minute in CD quality. MP3 compresses audio so cleverly that files become roughly ten times smaller while sounding very close to the original. It plays on every device.
When to keep WAV
MP3 is lossy, so keep your WAV if you still want to mix, master or edit the audio professionally. For sharing, listening, uploading demos or sending voice recordings by email or messenger, MP3 is ideal. Metadata such as titles may not always carry over from WAV.
