Convert M4A to WAV
Convert M4A voice memos into WAV files ready for transcription tools and audio editors.
What happens when you convert M4A to WAV
Decodes Apple M4A/AAC audio into uncompressed PCM WAV so it can be edited sample by sample. Nothing further is lost in the decode, but the compression AAC already applied is permanent.
Good for
- Editing Voice Memos or iTunes audio in a DAW
- Preparing recordings for transcription or acoustic analysis
- Feeding tools that only accept uncompressed audio
Worth knowing
- Expect roughly 10 MB per minute of stereo audio.
- Decoding does not restore what AAC discarded.
- DRM-protected files cannot be decoded.
