Binaural sound reproduction apparatus and method, and recording medium
Abstract:
A binaural sound reproduction apparatus includes a correction filter operable to filter an input sound signal that is recorded using a binaural recording microphone and to supply the filtered signal to a headphone, an adaptive filter to which the input sound signal is supplied, and a difference detector determining a difference between a sound signal that is obtained by collecting a sound reproduced by the headphone using a sound-collecting microphone that is the same as the binaural recording microphone, or that has a similar characteristic to that of the binaural recording microphone, and a sound signal output from the adaptive filter, and for transmitting the difference to the adaptive filter. The adaptive filter determines the inverse of a synthesis characteristic from the headphone to the sound-collecting microphone based on the input sound signal and the difference, and sets the determined characteristic as a characteristic of the correction filter.
