How It Works
Choose the M4A file
Drop the file above or tap the box to pick it.
Convert to WAV
The converter decodes the AAC audio and writes a WAV.
Download the WAV
Preview it, then save it for your editor or upload.
When you need WAV from an M4A
DAWs, sample libraries, radio and podcast submissions, transcription services and many upload forms ask for WAV. Converting the M4A once gives you a file every one of them accepts.
WAV also edits cleanly: cut, fade and export as often as you like without adding compression each time.
