Abstract

We propose a sound-timbre control technique that uses estimates of the resonance modes in a room. The key concept introduced here is that the resonance modes in a room where a musical instrument is played can be treated as controllable parameters of that musical instrument. By making full use of these additional parameters, a wide variety of desired sounds can be realized. Simulation results show that rich and expressive effects are achieved by using the proposed system. In particular, each frequency component of a sound can be independently and minutely modified, which leads to an impressive timbre change.
