Abstract: A sound processing device includes a sound collection unit configured to record a sound signal, a tilt information acquisition unit configured to acquire tilt information on a tilt of the sound processing device, an azimuth estimation unit configured to estimate azimuths of a sound source in a plane in which the sound collection unit is arranged based on the sound signals which are recorded by the sound collection unit at least at two times; and an elevation angle estimation unit configured to estimate an elevation angle of the sound source with respect to the plane in which the sound collection unit is arranged based on the tilt information acquired by the tilt information acquisition unit and the azimuths estimated by the azimuth estimation unit at least at two times.

Abstract: An information presentation device includes an audio signal input unit configured to input an audio signal, an image signal input unit configured to input an image signal, an image display unit configured to display an image indicated by the image signal, a sound source localization unit configured to estimate direction information for each sound source based on the audio signal, a sound source separation unit configured to separate the audio signal to sound-source-classified audio signals for each sound source, an operation input unit configured to receive an operation input and generates coordinate designation information indicating a part of a region of the image, and a sound source selection unit configured to select a sound-source-classified audio signal of a sound source associated with a coordinate which is included in a region indicated by the coordinate designation information, and which corresponds to the direction information.
