Abstract. In this paper we discuss a setup for technology-mediated audience participation (TMAP) using smartphones and high-frequency
sound IDs. We describe a setup for playful music interaction composed of smartphones. In this setup the audience needs to
install a smartphone app. Using high-frequency sound IDs music samples and colors can be triggered on the audience’s smartphones
without the need to have an internet connection. The resulting soundscape is determined by the samples and parameters selected
by the artist as well as by the location audience members choose in the performance space.
We present the technical basis and iterative explorative design process of such a system for TMAP. The learnings from the
perspective of musicians were technical requirements such as low latency, reliability, as well as increasing the number of
possible sound samples and sound quality and we further present learnings on creating systems for TMAP from technical and
