程機能付きカラオケ装置。An audio signal obtained by reproducing an accompaniment tape at a regular speed is modulated with a carrier wave of frequency f1 in a first modulation section to generate a first modulated wave, and a first modulation wave is generated by a first filter section. A lower side band wave of the wave is extracted, and this lower side band wave is modulated with a carrier wave of frequency f2 in a second modulation section to generate a second modulated wave, and a second filter section generates a lower side band wave of the second modulated wave. A karaoke device with a pitch function, which extracts waves and outputs the lower sideband waves as audio, and adjusts the pitch of an accompaniment that is output as audio by changing the frequency F2-f1.
