Title:
マルチサウンドの入力を聴覚的に分離するDSPベースの装置
Document Type and Number:
Japanese Patent JP2012531145
Kind Code:
A
Abstract:
There is provided a unique signal processing technique for localizing and characterizing each of a number of differently located acoustic sources. Specifically there is provided a method for auditory segregation of multiple voice inputs comprising the steps of: receiving a plurality of voice input signals from different source locations; filtering said voice input signals with head related transfer functions (HRTF) using a digital signal processor (DSP) thereby assigning the voice input signals to different locations in virtual auditory space; and changing the HRTF filtered voice input signals in two dimensions, wherein pitch is changed and the signal is filtered with different filters emulating vocal tracts of different sizes thereby further segregating the voice input signals from each other.
