摘要： The signal processing apparatus receives an input acoustic signal, and amplitude-modulates the received input acoustic signal to generate an output acoustic signal having an amplitude change corresponding to a frequency of a gamma wave, and outputs the generated output acoustic signal.

摘要： A signal processing apparatus receives an input acoustic signal, acquires a first acoustic signal having a periodic variation corresponding to the frequency of gamma waves, and outputs an output acoustic signal based on the acquired first acoustic signal and the second acoustic signal. The second acoustic signal is based on the input acoustic signal.
