AudioQueue together with AudioUnit (VoiceProcessingIO) - possible?

 Hi,

I developing app that is using AudioQueues for kind of VOIP. Low latency is not necessary in my case, so that I decided to use audio queues.

Everything is working fine, expecting echo issue, when audio output is recorded by microphone and send back and forth to second device. Digging deeply into CoreAudio docs, I found that this can be resolved on AudioUnits level, using VoiceProcessingIO.

I just wonder, if I have to rewrote all my code and use audio units, or if it possible to "plug in"  VoiceProcessingIO into my current, AudioQueue based code. Any ideas?

Thanks,

Jindrich
