摘要：
[Object] To provide a structure that can effectively reduce a noise containing a component varying in characteristic.
[Solution] A signal processing apparatus including: a signal processing section configured to generate a first noise reduction signal using an adaptive filter on the basis of a signal output from a first input apparatus, and cause the generated first noise reduction signal to be output by a first output apparatus, and generate a second noise reduction signal using a fixed filter on the basis of a signal output from a second input apparatus, and cause the generated second noise reduction signal to be output by a second output apparatus.
