I am looking for a good gem / plugin for converting user-downloaded audio files to different formats. One of the formats I'm interested in is converting to Apple.caf with ima4 compression for inclusion in the iPhone app.
I have been using afconvert on my mac for this so far, but I need to do this on my Linux server, server side. Ideally, I could work in a paper clip.
As an additional solution, ffmpeg may work, but I have not seen any .caf options for it. Does anyone know one thing?
