avaudioplayer

I want to generate a sound wave programmatically and play it with AVAudioPlayer. I have the code to encode my waveform as linear PCM, 44100Hz, mono, 8 bits per sample.

I am not clear on what kind of envelope I need to wrap around this buffer so that AVAudioPlayer recognizes it as PCM.
