Signal processing apparatus, signal processing method and audio correspondence presentation device

PROBLEM TO BE SOLVED: To provide a signal processor which allows a collection state of voices to be visually checked.SOLUTION: According to one embodiment, a signal processor comprises separation means, estimation means, and user interface means. The separation means separates a plurality of signals including signals being received at different positions and arriving from different bearings by a separation filter and outputs a plurality of separation signals. The estimation means estimates an arrival bearing for each of the plurality of separation signals and associates the plurality of separation signals with emission sources of the signals. The user interface means presents situation in which the plurality of separation signals is associated with the emission sources of the signals.SELECTED DRAWING: Figure 1
