IPC: H04R5/02
Filed: 2002-06-21
Abstract: PROBLEM TO BE SOLVED: To provide a method for processing and transducing audio signals for directive channel processing in multichannel audio systems. SOLUTION: An audio system has a first audio signal and a second audio signal each having amplitudes. A method for processing audio signals includes a step of dividing the first audio signal into a first spectral band signal and a second spectral band signal, a step of scaling the first spectral band signal by a first scaling coefficient proportional to the amplitude of the second audio signal, and a step of scaling the first spectral band signal by a second scaling coefficient to create a second signal portion. Also, other aspects include application of the signal processing method to multichannel audio systems, and to audio systems having different comb inations of directional loudspeakers, full range loudspeakers and limited range loudspeakers.
