Output format: wav

A bare .aac or ADTS stream is fine for playback and awkward for everything else, because editors want samples rather than a compressed bitstream. Decoding it once into a WAV produces a file that any audio tool will load without complaint. The decode runs here in the browser and the result is written straight to your downloads.

Frequently asked questions

Does decoding to WAV restore what AAC removed?
No, and no tool can. What the WAV gives you is a clean starting point that will not lose anything further as you cut, mix and export.
Why is the WAV so much bigger than the AAC?
AAC stores a clever approximation while WAV stores every sample literally. A twenty to one difference in size is entirely normal.
Will a recording from my phone work?
If it plays, it converts. Recordings wrapped in M4A belong on the M4A page instead, since that is the same audio inside a different container.
