Listening from the Booth: Multi-Perspective Auralisation and Theatrical Sound Engineering

Abstract
Sound engineers doing live mixing for theatre must manage the balance between on-stage acoustic sources and electro-acoustic sounds diffused in the hall. They have to trigger, spatialise and mix pre-recorded and live sounds, while actors perform. Typically confined to the control booth of unfamiliar venues, they need to adapt to a listening perspective that differs significantly from the audiences experience in the stalls or the balconies. This work engages with sound studies, virtual acoustics, and archival practices to investigate complementary questions.
How does the acoustic dissociation between the control booth and the rest of the venue influence the technical and aesthetic decisions of sound engineers? How would contemporary engineers interpret archived theatrical soundtracks when guided by annotated scripts? To address these questions, the research unfolds in four stages: capture multiple High Order Ambisonics Room Impulse Responses (HOA-RIRs) from emblematic theatres in So Paulo, Brazil, combining multiple sources and listening positions; build a real-time convolution engine, using the captured HOA-RIR with actors voices and archival soundtracks from the collection of Brazilian theatrical sound designer Tunica Teixeira; invite sound engineers to perform mixing tasks in a virtual acoustic environment, guided by Tunicas annotated scripts; and use the task metrics and structured questionnaires to assess the impact of multi-perspective listening on their technical and aesthetic decisions.
