A novel adaptive stereo sound system with self-generating sound-based listener tracking

A novel adaptive stereo sound system is proposed. The proposed scheme consists of two parts: listener position tracking using self-generating sound signals, and space skew/crosstalk cancelation.

Summary:A novel adaptive stereo sound system is proposed. The proposed scheme consists of two parts: listener position tracking using self-generating sound signals, and space skew/crosstalk cancelation. To verify the effectiveness of the proposed system, a positioning accuracy test and a subjective listener's test were carried out. It was shown that the probability of a mean squared positioning error of less than 0.07m 2 ranged from 70% to 90% when hand-clap signals were used in a small room. The results from the subjective listening test showed that 71% of the total stimuli were perceived as coming from the desired virtual location, regardless of the listener's position.
