Invoke: A Collaborative Virtual Reality Tool for Spatial Audio Production Using Voice-Based Trajectory Sketching

VR could transform creative engagement with spatial audio, given affordances for spatial visualisation and embodied interaction. But, issues exist addressing how to support collaboration for spatial audio production (SAP). Exploring this problem, we made a VR voice-based trajectory sketching tool, named Invoke, that allows two users to shape sonic ideas together. In this paper, thematic analysis is used to review two areas of a formative evaluation with expert users: (i) video analysis of VR interactions; and (ii) analysis of open questions about using the tool. Implications present new opportunities to explore co-creative VR tools for SAP.
