IRIS presented at EAA Symposium in Berlin
14 April 2014
We recently attended the "EAA Joint Symposium on Auralization and Ambisonics" which was held at the Berlin Musical Instrument Museum at the beginning of April.
Daniel Protheroe gave a poster presentation entitled, "Measurement and visualisation of room responses in level, time and direction". This presented the performance of IRIS with the results of several different room measurements. Click here to download a pdf of the poster.
