MP3. MP3 throws away sound the ear is unlikely to notice, using a psychoacoustic model, so a song shrinks to roughly a tenth of its CD size.
WAV. WAV stores raw PCM samples with no compression at all. What you save is exactly what the editor sees, which is why studios and editors use it.
What happens to quality
WAV is lossless, but it can’t restore what the MP3 encoder already removed. You get an exact copy of the MP3 sound in a format editors accept, at a much bigger file size. Hear the difference between lossless and MP3 yourself.
