Using afconvert from iOS

Question

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

Answer 1

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.
