Sound Environment Control Using an Immersive Audio System — Advancing Sound Experiences for Creators and Listeners Using Active Field Control

Abstract

Spatial and immersive systems have gained popularity in recent years and are broadly used in various types of applications to realize natural or augmented sound environment. To create a variety of sound environment freely and flexibly, Yamaha immersive audio system, known as Active Filed Control (AFC), has two functions. One is "sound source control" based on object-based audio rendering technique and another is "sound field control" based on acoustic enhancement technology. This paper presents several unique solutions applying immersive audio systems that use either or both sound source control and sound field control. We conducted post-event acoustic measurements or survey of questionnaire supporting that intended acoustic controls had been successfully implemented.
