Augmented Acoustics for Ensembles
* Presenting author
Abstract:
Augmented acoustics can create the acoustic impression of concert halls in small rooms by adding artificial reverberation to the direct sound. At the previous DAGA, we presented a stand-alone software tool that achieves this by simple hardware means for a single musician. Practical application of the tool revealed that headphones and even smallest microphones on the instrument sometimes impede the natural movement of the musician. In contrast, our further development works with loudspeakers and microphones surrounding the musician at a larger distance, e.g. close to the walls of the real room. This setup is particularly applicable to ensembles of musicians. Thus, our tool can be used to study the influence of the room on the interaction between musicians. Our contribution presents the hardware setup and signal processing of the ensemble tool, its level coverage in dependence of the number of microphones based on simulations and measurements, and simple strategies to reduce feedback.
