Title:
AUDIO SIGNAL PROCESSING METHOD, PARAMETERIZATION DEVICE FOR SAME, AND AUDIO SIGNAL PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/099429
Kind Code:
A1
Abstract:
The present invention relates to an audio signal processing method, a parameterization device for same, and an audio signal processing device. The present invention provides an audio signal processing method, a parameterization device for same, and an audio signal processing device, the method being characterized by comprising the steps of: receiving input audio signals; receiving at least one BRIR filter coefficient for the binaural filtering of the input audio signals; converting the BRIR filter coefficient(s) into a plurality of sub-band filter coefficients; obtaining flag information indicating whether or not the length of the BRIR filter coefficient(s) on a time domain exceeds a preset value; cutting the respective sub-band filter coefficients on the basis of filter order information obtained using at least a part of characteristic information extracted from the relevant sub-band filter coefficients; and filtering the respective sub-band signals of the input audio signals by using the cut sub-band filter coefficients.
