A protected M4P from the old iTunes store is a different thing and will not decode here or anywhere else without the original account. Their caps exist because every conversion runs on a machine they rent. Yours runs on the machine in front of you.

  1. 1

    Where your M4A came from

    An M4A is what an iPhone voice memo saves as, and what an Apple Music or iTunes purchase arrives as. It is AAC audio in an MPEG-4 container, which is why the extension looks like a video file with a letter changed.

  2. 2

    Why you are converting it

    An editor, a sampler or a transcription pipeline is the usual reason, and none of them want a compressed file. They want samples they can cut, stretch and analyse without a decoder in the way.

  3. 3

    What it costs

    Nothing further is lost, and the file gets roughly ten times larger. A three minute voice memo becomes about thirty megabytes, which is the price of giving software something it can work on directly.

FAQ

How do I convert M4A to WAV?
Drop the file on this page and press the button. It runs in your browser, so there is no upload, no account and no daily limit.
Why will my device not open a M4A file?
Car stereos, older DAPs, Windows media software from before about 2015 and a surprising number of upload forms will refuse it outright, usually without saying why.
Is there anything odd about M4A?
A protected M4P from the old iTunes store is a different thing and will not decode here or anywhere else without the original account.
Does converting to WAV lose quality?
Nothing further is lost, and the file gets roughly ten times larger. A three minute voice memo becomes about thirty megabytes, which is the price of giving software something it can work on directly.
Is the file uploaded?
No. The decode and the encode both happen in the page, and no request carries the audio anywhere. Watch the network panel while it runs.
