PROBLEM TO BE SOLVED: To provide a karaoke device which can easily and inexpensively measure a sound characteristic of a karaoke singing space without adding a new hardware resource.SOLUTION: Storage means 30 is stored with karaoke performance data for measurement for generating a frequency characteristic measurement sound signal for a frequency characteristic measurement of a karaoke singing space and the corresponding frequency characteristic measurement reference data. Point rating means 28 performs point rating processing in each point rating section based on reference data associated with the frequency characteristic measurement sound signal collected by the point rating means. Sound characteristic information processing means 32 regards a pitch corresponding to a point rating section smaller than a sound volume of the frequency characteristic measurement reference data by a predetermined value from the rating result as a dip frequency of the karaoke singing space and regards the pitch corresponding to the point rating section larger than the predetermined value as a peak frequency.SELECTED DRAWING: Figure 1 |
