Reference signal extraction for a semi-adaptive sound reproduction system under a noisy environment

Abstract

In this presentation, we propose a method of reference signal extraction for a semi-adaptive sound reproduction system based on semi-blind source separation under a noisy environment. Since the fluctuation of room transfer functions degrades the reproduced sound, we have proposed a semi-adaptive sound reproduction system that updates the inverse filters. However, in a noisy environment, it is difficult to observe only the reference signal. Therefore, we use semi-blind source separation to obtain a clean reference signal from a noisy observed signal.
