发明名称 Spectrally Uncolored Optimal Crosstalk Cancellation For Audio Through Loudspeakers
摘要 A method and system for calculating the frequency-dependent regularization parameter (FDRP) used in inverting the analytically derived or experimentally measured system transfer matrix for designing and/or producing crosstalk cancellation (XTC) filters relies on calculating the FDRP that results in a flat amplitude vs frequency response at the loudspeakers, thus forcing XTC to be effected into the phase domain only and relieving the XTC filter from the drawbacks of audible spectral coloration and dynamic range loss. When the method and system are used with any effective optimization technique, it results in XTC filters that yield optimal XTC levels over any desired portion of the audio band, impose no spectral coloration on the processed sound beyond the spectral coloration inherent in the playback hardware and/or loudspeakers, and cause no (or arbitrarily low) dynamic range loss.
