MULTICHANNEL AUDIO SIGNAL PROCESSING DEVICE

摘要

An audio signal processing device comprises signal supply means to supply over more than one input channel and per input channel over separate frequency subbands domain subchannels coded audio signals. Further filters are used to decode and synthesize the audio signals over the total frequency domain. Subband combination circuits are used for supplying respective input channels to the same subband combination circuit the signals from the same subband frequency domain audio signals.
