This paper describes an application that provides real-time high accuracy room acoustics simulation. Using a multitouch interface, the user can easily manipulate the dimensions of a virtual space while hearing the room's acoustics change in real-time. Such an interface enables a more fluid and intuitive control of our application, which better lends itself to expressive artistic gestures for use in such activities as sound design, performance, and education. The system relies on high accuracy room impulse responses from CATT-Acoustic and real-time audio processing through Max/MSP and provides holistic control of a spatial environment rather than applying generic reverberation via individual acoustic parameters (i.e. early reflections, RT60, etc.). Such an interface has the capability to create a more realistic effect without compromising flexibility of use.
