How can I see a flutter echo?
A flutter echo is easily seen on decay curves in a single-point response. It usually has a saw-tooth shape, with periodically repeated spikes due to reflections arriving at equal time intervals. You may click the Decay curves tab press T to reveal the detailed squared impulse response, as in the screenshot below. The 3D Billiard tool offers […]
Can Odeon show focusing effects?
It is possible to obtain a visualisation of focusing effects in ODEON in the 3D Billiard tool, like in the example of a dome below.
I use ODEON to simulate the spatial sound field distribution at a receiver. ODEON’s reflectogram in the single-point response displays only the early part. What about the rest of the response?
The Reflectrogram and 3D reflection paths tabs (available in Auditorium and Combined versions) display only the early part of the response for clarity, up to the transition order defined in the Room Setup. You may increase the transition order to see more ‘early’ reflections in these two tabs, but be aware this will also affect […]
