One-Time Engine Download
The first conversion fetches a ~31MB audio engine; your browser caches it, and everything runs locally from then on.
Questions about AAC and WAV.
Check the format behavior, limitations, and follow-up options before processing a real file.
Editing tools are pickier than players, and raw .aac streams trip up plenty of them. Converting to WAV decodes the AAC into plain 16-bit PCM — the universal input format for Audacity, DAWs, samplers, and speech-processing pipelines. It can't restore what the AAC encoding discarded, but it hands your tools the decoded audio with no codec dependency and no further loss.
