Abstract

In this work a simple and effective method is proposed in order to detect time intervals where only a single source is active (‘solo intervals’), in multiple microphone multiple source settings commonly encountered in audio applications, such as live sound reinforcement. The proposed method is based on the short term energy ratios between all available microphone signals and a single threshold value is used to determine if and which source is solely active. The method is computationally efficient and results indicate that it is accurate and fairly robust with respect to reverberation time and amount of source interference.
