PROBLEM TO BE SOLVED: To provide a signal processor capable of generating an input signal suitable for a multiway speaker.SOLUTION: A band division section divides an audio signal into signals of plural bandwidths corresponding to each of bandwidths of plural speaker units of a multiway speaker. A filter processing section performs wavefront synthesis filter processing on each of the audio signals of the divided bandwidths. After wavefront synthesis filter processing, the processed audio signals of respective bandwidths are supplied to the respective speaker units of the multiway speaker, each of which has respective bandwidth. This disclosure is applicable, for example, to signal processors etc.SELECTED DRAWING: Figure 4 |
