Frequently asked questions

Will converting M4A to WAV restore lost quality?

No. M4A audio is lossy AAC, and WAV is lossless, but WAV cannot bring back detail already thrown away during AAC compression — it simply stores the decoded M4A uncompressed. Start from the best M4A you have rather than one that was already re-encoded several times.

Why convert M4A to WAV instead of just keeping M4A?

Audio editors and DAWs work best with WAV, which has no decode step and edits cleanly without stacking re-encoding artifacts. Many editors, samplers and CD tools also refuse M4A outright, so converting to WAV is often the only way to load Apple audio into them at all.

How much larger will the WAV file be?

Expect roughly ten times the size: the AAC inside an M4A is decoded to raw PCM, and WAV stores every sample uncompressed, so a 5 MB M4A can become around 50 MB. Leave disk space for a whole album, and once your project is finished you can delete the WAVs and keep the small M4A originals.

Do I need WAV to burn an audio CD?

Usually yes. Audio CDs use uncompressed 44.1 kHz PCM, and most burning software either requires WAV or converts to it behind the scenes, so handing it ready WAV files avoids errors and a hidden extra conversion. It is also why a standard disc holds only about 80 minutes.

Which programs work better with WAV than M4A?

Audio editors and DAWs such as Audacity, Audition, Pro Tools and Logic, plus samplers, soundboards and video editors. They cut, loop and process WAV instantly with no decode step, and repeated saves never add compression artifacts. Several of them also do not open M4A directly, so a WAV copy is the reliable way in.

Can I convert several M4A files to WAV at once?

Yes. Add all your M4A files and click Convert — each one comes out as its own uncompressed WAV, which is handy when preparing a whole set of recordings for an edit session or a CD. There is no limit on the number of files in a batch.
