Abstract: An information processing apparatus and method, and a program, which are capable of conducting a search more easily and at a higher speed. The information processing apparatus includes a control unit configured to designate a designated section and a designated sound source of an audio signal including sounds of a plurality of sound sources, and configured to obtain a search result of a sound source signal similar to a signal of the designated sound source, the sound source signal having been searched for on the basis of the signal of the designated sound source in the designated section of the audio signal. The present technology is applicable to the information processing apparatus.

Abstract: The present technology relates to an information processing device, an information processing method, and a program that enable easier visualization of a sound field.
The information processing device includes: a calculation unit configured to calculate, on the basis of positional information indicating a plurality of observation positions in a space and an audio signal of sound observed at each of the plurality of observation positions, an amplitude or phase of the sound at each of a plurality of positions in the space at a first time interval; an event detection unit configured to detect an event; and an adjustment unit configured to perform, in a case where the event is detected, control such that the amplitude or the phase is calculated at a second time interval shorter than the first time interval. The present technology can be applied to a sound-field visualization system.

Abstract: Provided is a signal processing device including: a reverberation sound signal generation unit that generates a reverberation sound signal according to a sound source position of a virtual sound source and a distance to a reference point; and a drive signal generation unit that generates a drive signal for a speaker array by a wavefront synthesis filter, in which the drive signal generation unit generates the drive signal on the basis of a signal obtained by performing wavefront synthesis filtering processing on a signal obtained by convolving the reverberation sound signal with a signal of the virtual sound source and/or a signal obtained by performing wavefront synthesis filtering processing on the reverberation sound signal to make the reverberation sound signal into a virtual sound source.
