Does anyone know if it is possible to convert a sound file in the Documents directory from within an app? I have a recorded sound file that will be available in iTunes File Sharing that I need to convert. Is afconvert available from within iOS?
Thanks

I'm not sure from what format to what format you want to convert to, but converting audio during runtime is not as simple as the command-line afconvert tool.
Check out Apple's sample projects iPhoneACFileConvertTest or ConvertFile. I think these would be good starting points if you want to convert audio in your app.

For what it's worth, afconvert is just a handy command-line interface to the features of the ExtAudioFile API which you can find in -- Using this API you can convert from any supported file format/audio format combination TO any supported file format/audio format combination.
