PROBLEM TO BE SOLVED: To provide a system capable of easily determining whether or not performance based on detected codes is suited to an acoustic signal in a code detection device.SOLUTION: A code detection device includes: a code detection part 31 for analyzing an acoustic signal and detecting codes performed in the acoustic signal; data performance means for performing a specific range of the acoustic signal; code performance means 40 for performing codes detected in the specific range by a built-in sound source; and sound reproduction means 8 having a first channel and a second channel for simultaneously reproducing performances by the data performance means and the code performance means 40. In reproduction by the sound reproduction means 8, the performance by the data performance means is reproduced by the first channel and the performance by the code performance means 40 is reproduced by the second channel. |
