Abstract

This paper presents the utruchirp software, a tool for measuring impulse responses and modelling room acoustics in real time through auralisation based on convolution using those responses. Utruchirp is the result of concerns and needs emerging from the authors’ ongoing artistic practice, exploring room scale acoustic feedback as material for live performance, installations, and fixed media pieces as utrumque. The paper provides the technical and, more importantly, the artistic details of the development of utruchirp and its features, highlighting those that are the direct result of insights from artistic work: Monitoring of all stages of measuring and signal processing, auralisations of the measurements from within the measurement process, and integrated round trip delay estimation. Finally, it points out future directions and features that are to be explored next, with an invitation for collaborative efforts, aiming to bring the sensibilities of musical instruments to our measurement tools.
