Abstract:
1. In an audio system having a plurality of input channels, a method for processing audio signals comprising: band pass filtering each of the plurality of input channels to provide band pass filtered audio signals corresponding to each of the plurality of input channels; low pass filtering each of the plurality of input channels to provide low pass filtered audio signals corresponding to each of the plurality of input channels; high pass filtering each of the plurality of input channels to provide high pass filtered audio signals corresponding to each of the plurality of input channels; a first combinatorial processing of the band pass filtered audio signals corresponding to a first group of said plurality channels to provide a first bass audio signal stream including frequencies in a first spectral band; a second combinatorial processing of the band pass filtered audio signals corresponding to a second group of said plurality of channels to provide a second bass audio signal stream including frequencies in said first spectral band; and a third combinatorial processing of the low pass filtered audio signals corresponding to said plurality of channels to provide a third bass audio signal stream including frequencies in a single second spectral band, said second spectral band including lower frequencies than said first spectral band.
