Does anyone know of a small, free, simple, safe and malware-free software program that converts M4A to WAV? I'd be grateful. Anna Frodesiak (talk) 08:51, 29 March 2019 (UTC)
Did you read the part of the Audacity page entitled "Importing M4A (AAC) and MP4 files"? iTunes may be a source but is not the format. The instructions I posted show that you need to load a couple of libraries -- have you done that? Martin of Sheffield (talk) 10:30, 29 March 2019 (UTC)
Yes, I'm definitely an idiot. VLC converts fine. Been using it for years, never knew. Thank you Martin, and sorry to waste your time. Best, Anna Frodesiak (talk) 10:32, 29 March 2019 (UTC)
"ffmpeg -i file.m4a -vn file.wav" should work. The -vn gets rid of the video stream since .wav is an audio-only format. 67.164.113.165 (talk) 09:10, 30 March 2019 (UTC)
