Crosstalk clearing system, method for keeping tone quality and its parameter design method

Abstract

The invention is used to remove the cross talk generated from a two-channel sound source. The method comprises: providing a sound inputting device used for inputting a two channel sound source; setting a transfer function relation between the cross talk removing system and the user's head to get an outputted transfer pulse response; setting the antarafacial output transfer function pulse of the outputted transfer pulse response level off to zero; setting the homolateral output transfer pulse response of the outputted transfer pulse response to be delayed than the homolateral head transfer pulse response of the head transfer function; after a reversed calculation, getting the parameter of the cross talk removing system; using the parameter to make filter to get the output signals.

Description

technical field [0001] The invention relates to a crosstalk elimination technology, in particular to a crosstalk elimination system, method and parameter design method capable of maintaining sound quality. Background technique [0002] When using speakers to reproduce three-dimensional sound effects, cross-talk (cross-talk) cancellation system plays a very important role. The main goal of the known crosstalk cancellation system is to compensate the same-side head transfer function (Head-Related Transfer Function, also known as head-related transfer function) and eliminate crosstalk and equalize (equalize) the same-side head transfer function . However, in order to compensate for the poor low-frequency and high-frequency response of the same-side head transfer function, the crosstalk cancellation system needs to have a large gain, so that the crosstalk is also amplified in the low-frequency and high-frequency bands. , so known crosstalk cancellation systems are prone to hig...
