About the M4A to WAV Converter
Many audio editors, transcription services and samplers only accept WAV. Converting M4A to WAV gives you an uncompressed file that opens everywhere.
If the M4A contains lossless ALAC audio, the WAV is a perfect copy. If it is AAC, the WAV keeps the decoded sound exactly as you hear it now but cannot restore detail removed by AAC.
How to use the M4A to WAV Converter
- Drop your M4A files onto the converter. WAV is already selected.
- Keep 16-bit for voice memos and most music, or choose 24-bit for editing headroom.
- Click Convert and download the WAV files.
Frequently asked questions
How do I convert an iPhone voice memo to WAV?
Share the memo from the Voice Memos app to Files or your computer, drop the .m4a file onto this page and click Convert.
Why is the WAV file so much bigger?
WAV is uncompressed and uses about 10 MB per minute of stereo audio, while M4A is compressed. The bigger file does not mean better sound, only easier editing.
