M4A to WAV details

First, M4A to WAV reads M4A source files and prepares WAV output for the audio workflow. Next, M4A to WAV keeps the conversion path simple with no extra controls. Additionally, Files and text stay in the browser session.

Decode an.m4a file (an MP4 container holding an AAC audio stream; the format used by Apple Music downloads, iPhone voice memos, and many podcasts) 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 inside M4A is a lossy format, so the WAV will faithfully copy the decoded audio but won't recover information that was discarded during the original encode; you can't get true lossless from a lossy source. The conversion runs entirely in your browser via ffmpeg.wasm; nothing is uploaded.
