Adaptive Mixing of Sub-Band Signals

摘要

A method includes receiving a first microphone array processing signal (associated with a frequency band that includes a plurality of sub-bands) and receiving a second microphone array processing signal associated with the frequency band. The method includes generating a first output corresponding to a first sub-band based on the first microphone array processing signal and generating a second output corresponding to the first sub-band based on the second microphone array processing signal. The method includes generating a third output corresponding to a second sub-band based on the first microphone array processing signal and generating a fourth output corresponding to the second sub-band based on the second microphone array processing signal. The method includes performing a first set of microphone mixing operations to generate an adaptive mixer output for the first sub-band and performing a different set of microphone mixing operations to generate another adaptive mixer output for the second sub-band.

1. A method comprising:
receiving a first microphone array processing signal, wherein the first microphone array processing signal is associated with a frequency band that includes a plurality of sub-bands; receiving a second microphone array processing signal, wherein the second microphone array processing signal is associated with the frequency band that includes the plurality of sub-bands; generating a first output based on the first microphone array processing signal, wherein the first output corresponds to a first sub-band of the plurality of sub-bands; generating a second output based on the second microphone array processing signal, wherein the second output corresponds to the first sub-band of the plurality of sub-bands; generating a third output based on the first microphone array processing signal, wherein the third output corresponds to a second sub-band of the plurality of sub-bands; generating a fourth output based on the second microphone array processing signal, wherein the fourth output corresponds to the second sub-band; performing a first set of microphone mixing operations to generate a first adaptive mixer output associated with the first sub-band; and performing a second set of microphone mixing operations to generate a second adaptive mixer output associated with the second sub-band, wherein the second set of microphone operations is different from the first set of microphone mixing operations.
