Why convert M4A to WAV

Recorded an idea on your phone? iPhone voice memos and many Apple exports are M4A, which not every DAW, sampler or Windows tool opens cleanly.

This converter writes a standard PCM WAV so the audio drops straight into your session.

Phone ideas into a session

Bring a voice memo or hummed melody into your DAW.

Samplers and hardware

Most hardware samplers read WAV, not M4A.

Editing and podcasts

Edit without codec issues in your editor.

M4A to WAV and audio quality

If the M4A holds AAC, the WAV will sound the same as the M4A. No detail is added, but no more is lost either, and editing a WAV won't stack compression.

If the M4A holds lossless ALAC, the WAV is a true lossless copy.

No. The conversion happens in your browser.
