Recently, the improvement of network resources enables us to distribute the contents in real-time. This paper presents the low-delay coding of applause sound and hand-clapping sound with less parameter by means of synthesizing these sounds at the receiver site. We found that a number of people clapping their hands were corresponding to a sound volume of applause. In other words, no one considers who is clapping. Additionally, on the hand-clapping sound, the time interval of clapping also should be important. Based on such information, preliminary experiments confirm that our approach, which synthesizes applause and hand-clapping sound from a few parameters, successfully generates natural applause and hand-clapping sound.
