Interference Canceller Library

lib_ic is a library which provides functions that together perform Interference Cancellation (IC) on two channel input mic data by adapting to and modelling the room transfer characteristics. lib_ic library functions make use of functionality provided in lib_aec for the core normalised LMS blocks which in turn uses lib_xcore_math to perform DSP low-level optimised operations. For more details refer to IC Overview.
