Abstract:
There is provided a local sound field forming apparatus including a local sound field forming filter coefficient recording unit that records an audio filter coefficient for forming a sound field by an evanescent wave, a filter unit that convolves 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 that reproduces a sound on the basis of the loudspeaker drive signal. The present technology can be applied to a local sound field forming apparatus.
