Patent ID: 10477309

Abstract:
The present technique relates to a sound field reproduction device, a sound field reproduction method, and a program that make it possible to further accurately reproduce a certain sound field.A feature amount extraction unit extracts a main sound source feature amount from a sound pickup signal obtained by picking up a sound from a main sound source. A main sound source separation unit separates the sound pickup signal obtained through the sound pickup with a microphone array that mainly picks up a sound from the main sound source into a main sound source component and an auxiliary sound source component using the main sound source feature amount. On the basis of the main sound source component and the auxiliary sound source component that have been separated, a main sound source emphasis unit generates a signal in which the main sound source components are emphasized. A drive signal for a speaker array is generated from the signal generated in this manner and supplied to the speaker array. The present technique can be applied to a sound field reproduction apparatus.
