Apparatus and method of noise and echo reduction in multiple microphone audio systems

摘要: Multiple microphone noise suppression apparatus and methods are described herein. The implement a variety of techniques that can be selectively applied to signals received using multiple microphones. at each the microphones independently processed cancel echo signal components generated from local audio source. cancelled may by some or all modules within separator operates separate otherwise isolate speech signals. include pre-processing de-correlator followed blind source separator. output post filtered provide separation de-correlation. separated non-linearly for further reduction, additional processing implemented following non-linear processing.
