发明名称 Apparatus and method for producing virtual acoustic sound
摘要 In one embodiment, a sound image is generated by applying first and second copies of a first input audio signal to first and second audio channels, respectively, to generate first and second output audio signals for the sound image. Each output audio signal is generated by (1) applying the corresponding copy of the first input audio signal to a corresponding source placement unit (SPU) to generate M delayed, attenuated, and weighted audio signals, A>1; (2) applying each delayed, attenuated, and weighted audio signal to a corresponding eigen filter to generate one of M eigen-filtered audio signals; and (3) summing the M eigen-filtered audio signals to generate the corresponding output signal. In an alternative embodiment, M copies of a first input audio signal are eigen-filtered prior to applying first and second copies of the resulting eigen-filtered signals to first and second audio channels, respectively.
