Document Type and Number:
WIPO Patent Application WO/2013/145578
Kind Code:
A1
Abstract:
Provided are an audio processing device, audio processing method, and audio processing program that can accurately acquire solely desired audio from a signal in which the desired audio and other signals are mixed. The audio processing device is provided with: a distance computation unit (102) for calculating the distance from an input signal to standard patterns of a plurality of mixed signal spectra calculated by respectively combining the standard patterns of a plurality of desired audio spectra, the standard patterns of a plurality of undesired audio spectra, and the standard patterns of a plurality of noise audio spectra; and a desired audio spectrum expected value calculation unit (104) for calculating an expected value of a desired audio spectrum within the input signal, by using the distances calculated by the distance computation unit (102).
