Abstract

In a church in Weimar, Germany, a multi-track recording was made of a choir concert. Instead of trying to include the acoustics of the church in the recording, the impulse responses were recorded separately using a new measurement technique where a microphone is slowly moving along a circle. The microphone measures the pressure as well as the velocity response, enabling discrimination between wave field components from different directions and extrapolation of the data to other virtual microphone positions. This way, the responses can be estimated at all listening places of interest, and convolved with the 'dry' recording of the singers' voices for reproduction by Wave Field Synthesis. The measurements were done within the framework of the CARROUSO project.
