Playing portion of an audio file on iPhone

Does anyone knows how to play a portion of a sound file on the iPhone? Using the SDK, or any other library (Cocos Desnhion...).

I know how to play an entire so开发者_StackOverflow中文版und, but not an exact portion of it (eg. from 2,5ms to 6ms).

Thanks!

AVAudioPlayer has a currentTime property. Set it to start playing the file at a specific time mark and then watch its progress to stop playing when it reaches a desired mark.
