使用流行的商业视听传输系统，如现场观看系统，现场表演越来越受欢迎。提出了一种实时观看的真实感增强方法。本文介绍了一种用于掌声传播自动化的掌声声提取方法，并利用现场录制的声源进行了模拟实验，以评估掌声声提取性能。我们使用自适应滤波器来强调掌声，并利用信号幅度信息提取掌声。实验评价表明，在各种条件下，从表演声源中提取的掌声声基本正确。
Live performances are increasingly appreciated using popular commercial audiovisual transmission systems, such as live viewing systems. A reality enhancement method for live viewing had been proposed. This paper describes an applause sound extraction method for automation of applause sound transmission and a simulation experiment using the sound source recorded live at the venue to assess the applause sound extraction performance. We used an adaptive filter to emphasize applause sounds and extracted them using signal amplitude information. The experimental evaluation showed that the applause sound was extracted almost correctly from the performance sound source under various conditions.
