Abstract:
Provided is the signal processing device including: a signal analyzing unit configured to analyze a second audio signal based on a first audio signal which is input and a sound collected through a microphone; a cancellation processing unit configured to generate a cancellation signal for canceling the second audio signal; and a parameter generating unit configured to generate a control parameter used in the cancellation processing unit based on a result of analysis performed by the signal analyzing unit.

Claim (Index 9):
A non-transitory computer-readable medium having stored thereon computer-executable instructions which, when executed by a signal processing device, cause the signal processing device to execute operations, the operations comprising:\n inputting a first audio signal; inputting a second audio signal collected through a microphone, wherein the second audio signal is a noise signal; generating a cancellation signal to cancel the second audio signal in a frequency band; and determining a masking effect of the first audio signal and the noise signal based on frequency characteristics of the first audio signal, wherein the cancellation signal is not generated when the noise signal is masked by the first audio signal.
