Abstract:
1. In an audio system having a plurality of input channels, a method for processing audio signals comprising: a first combinatorial processing of the audio signals in a first group of the plurality of the input channels to provide a first combined audio signal stream; a second combinatorial processing of the audio signals in a second group of the plurality of the input channels to provide a second combined audio signal stream, wherein the second group of the plurality of input channels does not include any of the input channels that are in the first group; a third combinatorial processing of the first combined audio signal stream and the second combined audio signal stream to provide a third audio signal stream; a band pass filtering of the first combined audio signal stream to provide a first band pass filtered bass audio signal stream including frequencies in a low frequency spectral band; a band pass filtering of the second combined audio signal stream to provide a second band pass filtered bass audio signal stream including frequencies in the low frequency spectral band; a low pass filtering of the third audio signal stream to provide a low pass filtered third bass audio signal stream including frequencies in a second, very low frequency spectral band, the second very low frequency spectral band including lower frequencies than the low frequency spectral band; and transmitting each of the first band pass filtered bass audio signal stream, the second band pass filtered bass audio signal stream, and the low pass filtered third bass audio signal stream to respective loudspeakers.
