摘要：A method for processing and transducing audio signals. An audio system has afirst audio signal and a second audio signal that have amplitudes. A method forprocessing the audio signals includes dividing the first audio signal into a first spectralband signal and a second spectral band signal; scaling the first spectral band signal by afirst scaling factor proportional to the amplitude of the second audio signal; and scalingthe first spectral band signal by a second scaling factor to create a second signal portion.Other portions of the disclosure include application of the signal processing method tomultichannel audio systems, and to audio systems having different combinations ofdirectional loudspeakers, full range loudspeakers, and limited range loudspeakers.
