Abstract
Position information of sound source provides important cues for many audio analysis tasks. In this paper, we present a simple yet effective simultaneous audio source location and microphone placement approach to obtain the position information of stationary sound source. Motivation by the fact that audio source location and microphone placement can help each other, we consider these tasks as a joint inference framework so that more contextual information can be exploited. By fusing geometric properties of the sliding microphone-pair system with an error theory analysis, our location approach can achieve higher accuracy than conventional methods theoretically. Moreover, experimental results on our built real sound source location system are presented to demonstrate the effectiveness of the proposed approach.
