摘要：In a sound output device, a sound input unit acquires a sound signal reproducedby a reproduction device. A beat extractor extracts a beat component of the sound signal

based on a spectrogram, and generates a beat waveform having information of a beattiming and a beat intensity. An output signal generator amplifies the sound signal withthe beat waveform being a gain, using the beat timing and beat intensity which the beatwaveform has. A sound output unit outputs the beat enhanced sound signal as a soundby performing D/A conversion on the beat enhanced sound signal.
