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?
Can Odeon show focusing effects?
How can I see a flutter echo?

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 a visual way to detect flutter echoes, which appear as clusters of balls between parallel walls.

You may refer to the application note Detecting flutter echoes in ODEON for how to detect and handle flutter echoes in rooms.
