摘要：
A processing method and a processing apparatus for processing an output audio signal from an audio capture device. The output audio signal can be processed by a first processing module in a manner such that a preliminary signal and a first stage processed signal can be derived. The processing method includes providing power estimation signals, providing at least one cross power estimation signal, providing a leakage approximation and providing a control signal estimation.
