AUDIO PROCESSING

A computer-implemented method of processing an audio signal. The method comprises: receiving from two or more microphones, respective audio signals; deriving a plurality of time-frequency signals from the received audio signals, indexed by frequency, and for each of the time-frequency signals: deter...

description	A computer-implemented method of processing an audio signal. The method comprises: receiving from two or more microphones, respective audio signals; deriving a plurality of time-frequency signals from the received audio signals, indexed by frequency, and for each of the time-frequency signals: determining in-beam components of the audio signals; and performing post-processing of the received audio signals, the post-processing comprising: computing a reference level based on the audio signals; computing an in-beam level based on the determined in-beam components of the audio-signals; computing a post-processing gain to be applied to the in-beam components from the reference level and in-beam level; and applying the post-processing gain to the in-beam components.
