Sound Processing Device And Method And Program

Abstract: This technique relates to a sound processing device and method and a program which enable performance of audio reproduction with a higher degree of flexibility. An input unit accepts an input of an assumed listening position of sound of an object that is a sound source and outputs assumed listening position information indicating the assumed listening position. A position information correction unit corrects position information relating to each object on the basis of the assumed listening position information to generate corrected position information. A gain/frequency characteristic correction unit performs a gain correction and a frequency characteristic correction on the waveform signal of the object on the basis of the position information and the corrected position information. Further a spatial acoustic characteristic addition unit adds a spatial acoustic characteristic to the waveform signal on which the gain correction and the frequency characteristic correction have been performed on the basis of the position information relating to the object and the assumed listening position information. This technique is applicable to a sound processing device.
