Huge measurement series of RIR in the Cathedral of Lausanne
In a joint project, the Institute for Audiovisual Communications (LCAV) at EPFL, Switzerland, and the Institute of Technical Acoustics (ITA) at RWTH Aachen University, Germany, carried out a huge measurement series of Room Impulse Responses (RIR) in the Cathedral of Lausanne. Using state-of-the-art measurement technology, over 600 RIRs and nearly 90 Binaural RIRs (BRIR), each with a Signal-to-Noise Ratio (SNR) of over 70dB (broadband), were acquired resulting in a dense three-dimensional grid of high quality impulse response measurements over the entire seating area.
The complete set of RIRs/BRIRs along with a detailed description of the measurements is given here:

As a small teaser, enjoy an examplary auralization of measured BRIRs, packaged within a beautiful 360-degree visual tour in- and outside the Cathedral. Please make sure to wear appropriate headphones.
