Abstract
In this paper, we propose a stereophonic sound system using multiple smartphones. In the conventional sound systems using smartphones, all devices play the same signal so that it is difficult to provide true stereophonic effect. In order to solve this problem, we propose a novel sound system which can generate a virtual sound source at any location in such a way that smartphones at different locations play different signals with amplitude panning. By using the proposed system, we can generate more realistic stereophonic effect than the conventional system, and can control the sound effect by user's command. We developed the proposed system using commercial smartphones and verified that the developed sound system effectively provides the desired stereophonic effect.
