Abstract
The present invention relates to a cross-talk cancellation system (CCS) of multiple sound channels, which can provide a wider range of sweet spot. The CCS of multiple sound channels comprises: a CPU or DSP processor to input audio signal and output 3D sound signal; a filter to input 3D sound signal and proceed filtering processing to output sound signal; an array speaker to input and transmit sound signal for forming the sweet spot in front of the array speaker. The filtering processing is based on the normalized parameters of the CCS of multiple sound channels related to the frequency of 3D sound signal, the sound source signal processor can be the CPU or DSP processor.
