Frequently asked questions
Does WAV improve MP3 audio quality?
No. Converting a lossy MP3 to WAV cannot restore the audio detail discarded during MP3 encoding.
Why is the WAV much larger?
PCM stores audio samples without MP3’s lossy compression. It trades much more storage for a straightforward editing format.
