Abstract
A signal processing device of an embodiment includes a measurement signal generation unit that generates a measurement signal to be output from the sound source, a sound pickup signal acquisition unit that acquires sound pickup signals picked up by a plurality of microphones, a sound source information acquisition unit that acquires sound source information about a horizontal angle of a sound source, filters that have a passband set based on the sound source information and output a filter passing signal in response to input of the sound pickup signals, a phase difference detection unit that detects a phase difference between two sound pickup signals based on the filter passing signal, and a determination unit that determines a result of measurement of the sound pickup signals by comparing the phase difference with an effective range set based on the sound source information.
