Title:
AUDIO SIGNAL PROCESSING DEVICE, AUDIO SIGNAL PROCESSING METHOD, AND AUDIO SIGNAL PROCESSING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2017/188141
Kind Code:
A1
Abstract:
An audio signal processing device according to one embodiment is provided with an acceptance unit for accepting audio signals of a plurality of channels, a division unit for dividing the audio signal of each channel into a coherent component and a field component, and an output unit for outputting the coherent component and field component of each channel. In the dividing process, an estimated signal having highest correlation with the audio signal of a channel to be processed among estimated signals calculated using at least the audio signal of other than the channel to be processed, is extracted as the coherent component of the channel to be processed. Then, a difference of the audio signal of the channel to be processed and the coherent component is extracted as a field component.
