Convert MP3 to WAV
Expand MP3s into uncompressed WAV files for editing, sampling and audio production.
What happens when you convert MP3 to WAV
Decodes MP3 into uncompressed 16-bit PCM inside a WAV container. Nothing further is lost in this step, but nothing is recovered either — the audio that MP3 discarded is gone for good. What you get is a file that every editor and DAW can load and scrub without re-decoding.
Good for
- Loading audio into an editor or DAW that works best with PCM
- Feeding equipment and software that will not read compressed audio
- Preparing a file for sample-accurate editing or analysis
Worth knowing
- Files get much bigger — roughly 10 MB per minute of stereo audio.
- This does not restore quality. The result is a lossless copy of already-lossy audio.
- MP3's encoder delay can leave a very short silence at the start.
