A new Approach for Direct Interaction withGraphical Representations of Room ImpulseResponses for the Use in Wave Field SynthesisReproduction

摘要

Room simulation based on convolution is state of the art in modern audio processing environments. Mostof the systems currently available provide only a few controllers to modify the underlying room impulseresponses. The sound designer can manipulate one set of numeric parameters even in spatial reproductionsystems. This paper describes a new approach for the interactive control of room impulse responses basedon visualization and parameterization. The new principle is originally developed for the use in Wave FieldSynthesis systems and based on Augmented Reality user interfaces. An adaptation to conventional userinterfaces and other spatial sound reproduction systems is possible. The modification of the room impulseresponses is performed by direct interaction with 3D graphical representations of multi-trace room impulseresponses.
