Abstract:
1. A method comprising: performing a spatially selective processing operation on a first input, wherein the first input is a multichannel sensed audio signal input, to produce a source signal and a noise reference; filtering a second input, wherein the second input is a reproduced audio signal input, to obtain a first plurality of time-domain subband signals; filtering the noise reference to obtain a second plurality of time-domain subband signals; based on information from the first plurality of time-domain subband signals, calculating a plurality of first subband power estimates; based on information from the second plurality of time-domain subband signals, calculating a plurality of second subband power estimates; and based on information from the plurality of first subband power estimates and on information from the plurality of second subband power estimates, boosting at least one frequency subband of the reproduced audio signal input relative to at least one other frequency subband of the reproduced audio signal input.
