AAC to WAV details
First, AAC to WAV reads AAC and M4A source files and prepares WAV output for the audio workflow. Next, AAC to WAV keeps the conversion path simple with no extra controls. Additionally, Files and text stay in the browser session.
Decode an AAC stream; either a raw.aac file or an.m4a container; and re-encode it as 16-bit PCM WAV (CD quality). WAV is lossless and ideal for editing in a DAW, archival, or any pipeline that expects uncompressed audio. Note that AAC is a lossy format, so the WAV will be a faithful copy of the decoded audio but won't recover information that was discarded during the original AAC encode; you can't get true lossless from a lossy source. The conversion runs entirely in your browser via ffmpeg.wasm.
