Title:
ACOUSTIC SIGNAL PROCESSING DEVICE AND ACOUSTIC SIGNAL PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/155603
Kind Code:
A1
Abstract:
The present invention comprises a first correlated component separation unit (110) for generating a first correlated component signal by predicting a first signal from a second signal during a predetermined period and using the first correlated component signal to separate a first uncorrelated component signal from the first signal, a second correlated component separation unit (120) for generating a second correlated component signal by predicting the second signal from the first signal during the predetermined period and using the second correlated component signal to separate a second uncorrelated component signal from the second signal, a correlated component combination unit (130) for generating a combined correlated component signal by combining the first correlated component signal and second correlated component signal, a first gain multiplication unit (131) for generating a correlated component signal by multiplying the combined correlated component signal by a gain, a first signal adding unit (132) for adding the correlated component signal and the first uncorrelated component signal, and a second signal adding unit (133) for adding the correlated component signal and the second uncorrelated component signal.
