Abstract:
In a sound output device, a sound input unit acquires a sound signal reproduced by 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 beat timing and a beat intensity. An output signal generator amplifies the sound signal with the beat waveform being a gain, using the beat timing and beat intensity which the beat waveform has. A sound output unit outputs the beat enhanced sound signal as a sound by performing D/A conversion on the beat enhanced sound signal.
