Immersive Auralisations for Choral Ensembles

Résumé

Room acoustic modelling and the use of auralisations for the study and design of venues have been well investigated over recent decades. However, much of the existing literature focuses on a single user's experience in an immersive, offline auralisation. Interactive real-time auralisation studies can provide useful information for understanding the behaviour of a singular musician inside a virtual acoustic environment but are not fully representative of the general acoustic uses of musical venues. The study of ensemble behaviour inside real or virtual room acoustics is less frequent, limited by the practicalities of moving ensembles between physical spaces or spatial limitations within the sweet spot of virtual reproduction systems. In the context of a study on choir's behavioural modifications within a variety of (virtual) acoustics, a multi-person auralisation system was developed and calibrated to ensure its acoustical validity. The system was calibrated using STlate to ensure the virtual acoustics behaved as predicted via simulated room impulse responses. Professional choirs were studied as they performed in various virtual performance spaces. This study explores the development of the reproduction system, summarises performer responses to the acoustics, and proposes a framework for designing multiple-participant immersive auralization frameworks.
