Reverb effect in iPhone app

Question

Can anyone please give pointers how we can add re verb effect to a recording in an iPhone app?

Vocal live free on app store is a pretty good example of how I would want to include reverb effect.

Core Audio Overview in iOS documentation references reverb as an audio unit.

Any help beyond this will be helpful.

Answer 2

If you have access to the raw audio data, you can simply convolute it with corresponding reverberation finite impulse response (FIR) filter kernel.
