We have been studying a design method for a controller for binaural reproduction with loudspeakers. The gain of the controller amplifies errors due to external disturbances and system perturbations, and this leads to deterioration of the sound quality. Therefore, the gain should be suppressed to as low as possible. For this purpose, we formulate the design of the controller as a minimization problem of the gain, in which the H∞ norm of the controller is adopted as a measure of the gain. In this article, we also introduce a binaural reproduction system as an implementation example. This system virtually reproduces multichannel audio such as 22.2 multichannel audio using line array loudspeakers.
