IKA-SIM: A System to Generate Auditory Virtual Environments

Authors: Silzle, Andreas; Strauss, Holger; Novo, Pedro

AES Convention 116 · Paper 6016 · May 2004

Abstract

The basic requirements for an Auditory Virtual Environment (AVE) are presented and a system based on a physical approach (IKA-SIM), employing the mirror-image model to generate the early reflections, is described. The static and dynamic structure of the IKA-SIM software (written in C++) is shown in diagrams and the computational requirements for real-time performance are delineated. IKA-SIM is able to render rooms of arbitrary shape, to account for frequency dependent absorption factors, and to calculate high order reflections in real-time on a standard PC. The different interfaces for real-time interaction are presented. IKA-SIM supports headphone and loudspeaker reproduction. A new elevation panning algorithm for loudspeaker reproduction is introduced. Design aspects relevant to a real-time AVE system are presented.
