METHOD AND APPARATUS FOR PROCESSING MULTI-CHANNEL DE-CORRELATION FOR CANCELLING MULTI-CHANNEL ACOUSTIC ECHO |
摘要 |
Provided are a method and apparatus for multi-channel de-correlation processing for cancelling a multi-channel acoustic echo. The method includes: dividing an input multi-channel audio signal into units of frames to form multi-channel audio signals in units of frames; analyzing eigen values and eigen vectors related to the multi-channel audio signals by using the multi-channel audio signals in units of frames every time contents are modified; and separating the multi-channel audio signals in units of frames into a plurality of signal component spaces by using the analyzed eigen values and eigen vectors. |
