The method includes mounting electroacoustical transducers in a low frequency augmenting device. The electroacoustical transducers radiate different high frequency acoustic energy and common low frequency acoustic energy. The transducers may be part of directional arrays. The method is applied to multimedia entertainment devices.
CLAIM OF PRIORITY This application claims priority under 35 USC �119(e) to U.S. patent application Ser. No. 10/309,395, filed on Dec. 3, 2002, the entire contents of which are hereby incorporated by reference.
BRIEF SUMMARY OF THE INVENTION According to the invention, a method for processing audio signals includes receiving a first channel audio signal; separating the first audio channel signal into a first channel first spectral portion and a first channel second spectral portion. The method further includes a first processing, of the first channel signal first spectral portion, according to a first process represented by a first non-unity non-zero transfer function to provide a first channel first processed signal; a second processing, of the first channel first spectral portion, according to a second process represented by a second transfer function, different from the first transfer function, to provide a first channel second processed signal; and combining the first channel first processed signal and the first channel second spectral portion to provide a first channel first combined signal. The method still further includes transducing, by a first electroacoustical transducer, the first combined signal; combining the first channel second processed signal and the first channel second spectral portion to provide a first channel second combined signal; and transducing, by a second electroacoustical transducer, the second combined signal.
