LOCAL SOUND FIELD FORMING APPARATUS, LOCAL SOUND FIELD FORMING METHOD, AND PROGRAM

摘要

The present technology relates to a local sound field forming apparatus, a local sound field forming method, and a program that are capable of reducing sound leakage in an unintended direction.;The local sound field forming apparatus includes a local sound field forming filter coefficient recording unit configured to record an audio filter coefficient for forming a sound field by an evanescent wave, a filter unit configured to convolve the audio filter coefficient and a sound source signal to generate a loudspeaker drive signal, and a loudspeaker array that includes a plurality of loudspeakers including a directional loudspeaker, and is configured to reproduce a sound on the basis of the loudspeaker drive signal. The present technology can be applied to a local sound field forming apparatus.
