Impulse Responses
Since version 12, ODEON has been equipped with a powerful impulse response measuring system that is described in Chapter 12 in the manual and on our tutorials page . The measuring system in ODEON can load any impulse response recorded in .Wav format. Some examples can be downloaded from this page and can be used in combination with the virtual models available with the ODEON installation.
Auditorium 21 at the Technical University of Denmark (DTU) was measured during March 2013. For this measurements the sweep generator in ODEON was used, with a sweep length of 4 sec. Click to get the Impulse Responses.
The byzantine church Hagia Sofia was modelled as part of the CAHRISMA project. The measured impulse responses are available here.
Recordings of hand-clapping in the room can work quiet satisfactory if not carrying the full equipment (lap-top, omni-directional speaker, microphone) with you. Using a small microphone pluged-in a smart phone or using just a mobile recorder can be adequate for capturing the sound behavior of the room, by utilizing hand-clapping or balloon explosions as the stimuli. The .Wav recording can easily be processed inside ODEON afterwards with the Load Impulse Response tool. Here you can download a .wav recording of hand claps in a series. ODEON detects and isolates the hand clap that gives the highest signal to noise ratio.
