Title: SOUND PROCESSING DEVICE AND METHOD, AND PROGRAM
Abstract:
This technology relates to a sound processing device and method, and a program which allow a sound field to be reproduced more appropriately. A microphone array picks up sound in a sound pickup space, and outputs a sound pickup signal obtained as a result thereof. A temporal frequency analysis unit performs temporal frequency transform on the sound pickup signal to obtain a temporal frequency spectrum. A direction correction unit calculates a correction angle for correcting the direction of the microphone array on the basis of correction mode information, and image information or sensor information. A spatial frequency analysis unit corrects the signal obtained by sound pickup by the microphone array by performing spatial frequency transform on the temporal frequency spectrum on the basis of the correction angle. This technology is applicable to a sound processing device.
