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.
