Real-ime ambisonic simulation of auditorium acoustics within a digital audio workstation environment
Barry Watson and Fraser D. Clark
This research investigates the feasibility of an ambisonic system to replicate the acoustic conditions experienced by solo musicians in a concert hall, allowing for the development of familiarity with a specific venue. Spatial impulse response measurements are taken at the hall and real-time convolution is employed to recreate the acoustics in a domestic setting. Reproduction is via four loudspeakers of a standard 5.1 configuration where digital audio workstation software and associated plug-ins perform routing and signal processing. The work supersedes related research by offering a integrated consumer-biased approach, affording greater accuracy in regard to the balance of direct/reverberant sounds within the simulation and greater scope for switching between stage and auditorium aspects and simulating venue occupancy.
