Re: ffmpeg guidance, please to convert m4b to mp3

If it can't be opened correctly by Audacity, is it possible the file is corrupted somehow?

Do you really want the results in separate chapters, or is a single non-chaptered file okay? ffmpeg would be a very simple command-line if you wish to write to a single file. If you need to separate by chapters, did you try using the nitrag script?

BTW, most video/audio editors use ffmpeg or one of it's components as it's engine. It is extremely powerful.
