I have app which is supported by core audio framework. App records voice from mic and plays it out through headphones. When I am at big room I can hear "echo" effect sound. Is it in core audio some property (maybe core audio unit property) which can solve this problem? Or some framework? Thank you for ideas! ;)

In your audio graph, try using the VoiceProcessingIO unit instead of the 'normal' RemoteIO unit. The VoiceProcessingIO unit includes echo cancellation, gain control and some other features that should help in your situation.
