Title:
SIGNAL PROCESSING DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2014/132499
Kind Code:
A1
Abstract:
This signal processing device suppresses noise components included in input sound signals by means of a coherence filter. The device has an iterative coherence filter processing function wherein coherence filter processing is repeated by inputting a signal that has undergone coherence filter processing as an input signal once again, and iterative processing is performed until the signal that has undergone coherence filter processing satisfies an iteration completion condition, thus enabling musical noise to be suppressed even if noise components are suppressed.
