SIGNAL PROCESSING DEVICE, SIGNAL PROCESSING METHOD, AND COMPUTER PROGRAM

摘要

[Problem] To provide a signal processing device that can effectively use resources for generating a noise canceling signal. [Solution] Provided is a signal processing device which is provided with: a signal analysis unit for analyzing a first sound signal, which is input, and a second sound signal based on sound picked up by a microphone; a cancellation processing unit for generating a canceling signal for canceling the second sound signal; and a parameter generating unit for generating control parameters used by the cancellation processing unit on the basis of results of analysis by the signal analysis unit.
