We detail a real-time application of active acoustics used to create a shared virtual environment over a closed audio network as a research-creation project exploring the concept of room participation in musical performance. As part of a concert given in the Immersive Media Lab at McGill University, musicians performed in a virtual acoustic environment to two audiences: an in-person one, and a second audience located in an adjacent but acoustically isolated space on the same audio network. Overall, the blending of computer-generated and acoustic sources created a specific use case for virtual acoustics, while the immersive capture and distribution method examined an avenue for producing a real-time, shared experience. Future work in this area includes audio networks with multiple virtual acoustic environments and distributions.
