Abstract: [Title of Invention] Signal processing apparatus, cognitive function improvement system, signal processing method, and program
A signal processing apparatus comprises means for receiving an input acoustic signal, means for acquiring a first acoustic signal having a periodic variation corresponding to the frequency of gamma wave, and based on the acquired first acoustic signal and the input acoustic signal and means for outputting an output acoustic signal based on the second acoustic signal.

Abstract: The signal processing apparatus has a means for receiving an input acoustic signal, and amplitude-modulates the received input acoustic signal to have an amplitude change corresponding to the frequency of the gamma wave, and the rise and fall of the envelope of the amplitude waveform. Means for generating an output acoustic signal that is asymmetric and means for outputting the generated output acoustic signal.
