To get the properties for any audio filetype that is supported on iOS, load the audio data into an AVAudioPlayer and examine its properties (in particular, the settings dictionary).

Can this be used to read audio from the ipod library? looks like ony the AVPlayer class can be used for that. If I use AVAudioPlayer I can't play the file or get anything from the settings dictionary. – roocell Oct 08 '11 at 15:16
