How can I deselect audio using iphone sdk? I will try to make the effect of "dj scratch". I'm talking about speeding up and slowing down and reversing audio samples in real time.
It is not as easy as you think. To get the real scratch effect, you will have to simulate the changes in the playback speed - the pitch shift to 0 Hz, and then again change the sound stream and the pitch shift back to the normal playback speed. This is not a trivial algorithm.
