About M4A to WAV

Recorded something on an iPhone and want to edit it in Audacity, GarageBand or another editor? Converting the M4A to WAV gives you an uncompressed file that every editor opens.

The conversion decodes the AAC sound inside the M4A and writes it out as WAV on your device.

WAV is uncompressed, so the file is much larger than the M4A: about 10 MB per minute in stereo. It doesn't sound better than the original, but you can now cut, mix and save it as often as you like without losing any more quality.

Voice Memos from an iPhone, recordings from dictation apps and AAC music files without copy protection all work. You can drop several files at once and download the WAVs together as a ZIP. Voice recordings are often personal, which is why the conversion stays on your device and nothing is uploaded.

The WAV keeps the length and the number of channels of the recording. Once the page has loaded, the converter works without an internet connection.
