Abstract
Official abstract text for this publication.
A method, device and computer program product for processing audio signals, the method including determining beamformer filter coefficients to be applied to the audio signals; applying the beamformer filter coefficients to the audio signals; outputting the filtered audio signals from an audio output comprising a plurality of speakers coupled with the device; and receiving at a microphone coupled with the device, the filtered audio signals output from the audio output. The filter coefficients are determined such that the filtered audio signals are suppressed when received at the microphone.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of processing audio signals at a device, the method comprising: determining beamformer filter coefficients to be applied to the audio signals, the determining comprising: outputting bandstop-filtered audio signals to the all but one of a plurality of speakers and an unfiltered audio signal to a remaining speaker of the plurality of the speakers; and estimating a time delay between the remaining speaker of the plurality of the speakers and a micro…
