PROBLEM TO BE SOLVED: To provide a technology for enabling a user side who listens to submission data to arbitrarily change the application of an acoustic effect to the sound of the submission data.SOLUTION: A karaoke machine 10 acquires first sound data input from a microphone 19 or a musical instrument 20, and generates second sound data obtained by applying an acoustic effect to the first sound data on musical performance based on the musical piece data of karaoke, and submits submission data including the first sound data and the second sound data recorded in this time to a host server 40. The karaoke machine 10 side which performs musical performance by using the submission data determines the submission data to be used for musical performance from among uploaded submission data. Also, when executing the musical performance using the submission data, the karaoke machine 10 determines which of the first sound data and the second sound data should be used, and acquires the determined sound data from the host server 40. Then, the karaoke machine 10 outputs a musical piece sound based on the musical piece data corresponding to the submission data and a submission sound based on the acquired first sound data or second sound data. |
