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.
