am making an application for iPhone/ipod Touch.
In that application I am recording the voice of a human, storing it in a file in NSTemporaryDirectory() and then playing it. So far I have used AVAudioPlayer and AVAudioRecorder but after some time when I record, it simultaneously plays the sound, I don't know why? And moreover my application crashes in iPhone 4.
Now could you please suggest me which framework to use which can do recording, changes pitch and can play and most importent which will work on all iPhones.
1. OpenAL
2. Core Audio
3. AudioToobox
