摘要：
A computer-implemented method for reducing undesired crosstalksignals on an inactive channel of a device comprising the stepsof: (i) determining system volume levels and associated signalamplitudes required to achieve a range of desired audio outputattenuation levels on an active channel of the device； (ii)determining a crosstalk compensation signal comprising a signalamplitude and associated phase shift required to reduceundesired crosstalk on the inactive channel of the device foreach desired audio output attention level in the range ofdesired audio output attenuation levels； and (iii) generating adesired audio output attenuation level on the active channel ofthe device by generating a signal at the determined systemvolume level and associated signal amplitude required to achievesaid desired audio output attenuation level, and generating acontemporaneous crosstalk compensation signal on the inactivechannel of the device by generating a signal at the determinedsignal amplitude and associated phase shift required to reducethe undesired crosstalk on the inactive channel.
