Convention Paper
Production Approaches, Loudspeaker Configurations, and Signal Processing Architectures for Live Virtual Acoustic Performance
AES Convention 152 · Paper 10606 · May 2022
Abstract
Production workflows and signal processing architectures are described for staging live virtual acoustic concerts at venues having different loudspeaker configurations. The idea is to provide the audience with an immersive experience, while giving the performers the monitoring and sense of space needed to occupy and interact with the simulated acoustic. The auralization processing and monitoring are described for loudspeakers located (a) centrally, radiating outward from near the stage; (b) around the venue perimeter, radiating inward toward the audience; and (c) throughout the hall. Detailed production procedures and signal processing architectures are described using virtual acoustics performances by Cappella Romana in the TivoliVredenburg Grote Zaal in Utrecht with centrally positioned loudspeaker arrays, the Ritz Carlton Ballroom in San Francisco with perimeter configured loudspeakers, and the Bing Concert Hall at Stanford University with loudspeakers mounted throughout the hall.
