Audio collecting device, has probability value specifying unit for specifying probability value, which is indicative for probability of existence of audio source in pre-determined direction

摘要

The device has a probability value specifying unit for specifying a probability value, which is indicative for a probability of an existence of an audio source in a pre-determined direction based on the difference of phase components. A suppression function evaluating unit evaluates a suppression function to suppress a sound input of another audio source based on the probability value. A signal correcting unit corrects a converted signal on a frequency axis, and a signal re-establishment unit re-establishes the corrected signal on the frequency axis as a signal on a time axis. Independent claims are also included for the following: (1) an audio collecting method with bundling (2) a memory product storing a computer program to perform the audio collecting method.
