M4A (AAC in an MPEG-4 container) is Apple's format — great for playback, but DAWs and audio production tools often prefer WAV. Decoding M4A to WAV strips the container and codec, leaving raw uncompressed PCM that any professional tool can import without issue.
When you’d want this conversion
- Importing iPhone voice memos, Voice Memos app recordings, or iTunes rips into a DAW.
- Using M4A audio in video editing software that requires WAV.
- Processing Apple-sourced audio through non-Apple tools.

Frequently Asked Questions
Can I import the WAV into any DAW after this conversion?
Yes. WAV is universally supported by every DAW — Pro Tools, Ableton, Logic, Cubase, GarageBand, Reaper, and Audacity all handle it natively without plugins.
Will iPhone voice memos convert correctly?
Yes. Voice Memos on iPhone save as M4A (AAC) files. This converter decodes them correctly to WAV, which you can then import into any audio editor.
What sample rate will the WAV have?
The WAV inherits the sample rate of the source M4A. iPhone voice memos are typically 44.1 kHz; high-quality recordings may be 48 kHz.
