Abstract
According to one embodiment, a signal processor includes: a plurality of loudspeakers configured to reproduce sound of a plurality of channels; a plurality of microphones configured to pick up sound of a plurality of channels; a detector configured to detect a user who is present in a direction of a space from which the microphones pick up the sound, and output directional characteristic information indicating a relative direction of the user to the loudspeakers; and a signal processor configured to switch contents of processing to reduce a disturbance signal included in a picked-up sound signal of the sound picked up by the microphones from the picked-up sound signal based on the relative direction indicated by the directional characteristic information.

An apparatus comprising:
- a plurality of loudspeakers configured to reproduce sound of a plurality of channels;
- a plurality of microphones configured to pick up sound of a plurality of channels;
- a detector configured to detect a user who is present in a direction of a space from which the plurality of microphones pick up the sound, and output directional characteristic information indicating a relative direction of the user to the plurality of loudspeakers;
- and
- a signal processor configured to switch contents of processing to reduce a disturbance signal included in a picked-up sound signal of the sound picked up by the plurality of microphones from the picked-up sound signal based on the relative direction indicated by the directional characteristic information.
A signal processing method performed by a signal processor comprising a plurality of loudspeakers reproducing sound of a plurality of channels and a plurality of microphones picking up sound of a plurality of channels, the method comprising:
- detecting, by a detector, a user who is present in a direction of a space from which the plurality of microphones pickup the sound to output directional characteristic information indicating a relative direction of the user to the plurality of loudspeakers;
- and
- switching, by a signal processor, contents of processing to reduce a disturbance signal included in a picked-up sound signal of the sound picked up by the plurality of microphones from the picked-up sound signal based on the relative direction indicated by the directional characteristic information.
