Convert AAC to WAV
Drop a .aac file and download a 16-bit PCM WAV. The source sample rate and channel count are preserved.
This is the conversion that gets a captured stream into an editor. Once the audio is PCM, cuts land on exact samples and no decoder sits between the file and the timeline.
Why ADTS gives editors trouble
A .aac file is a run of AAC frames with minimal headers. There is no index, no duration field, and no metadata, so a player has to scan the whole file to estimate length and cannot seek reliably. Some tools give up rather than guess.
After the conversion
Expect roughly 10 MB per stereo minute. Exports stream to browser disk storage when it is available, which keeps memory flat for long captures; without it, oversized jobs are refused instead of exhausting the tab.
Use FLAC output instead when the file needs to stay lossless but smaller.
