Hi everybody,

I read this forum since years. But I've never posted, mainly because of my difficulties to find the right words in english. Everytime when I come to this forum just to read a little bit and watch the newest fotos, I can't stop reading for hours. Its really hard to not getting addicted.

Today I thought I write to you and show you the link to a room mode calculator I wrote years befor to learn java. Most rooms that are discussed in this forum are non-rectangular rooms, but maybe one or another will find the calculator usefull.

http://amroc.andymel.eu

Its an java-applet. You can easily save screenshots (two mouse-clicks) of the mode distribution, the bolt-area, the 3D sketch, 2D floor, a function with the spacing between two adjacent modes over frequency or the bonello function. A table to copy the modes to MS Excel... funny little things.

For exsample, this is my room:

The distribution of modes (the longest lines are axial modes, then tangential modes and the shortes lines are oblique modes)

The bolt area with my room marked:

The modes per third (Bonello):
Image

The spacings between adjacent modes:
Image

and that is the room:
Image


I would love to see such screenshots in future discussions on this glorious forum. Maybe it helps someone out there.

Best regards to John, Rod and all the other members that made lots of hours of reading so addicting ;)

I have been using this calculator to get a general idea of rooms, in purchasing a new home. I real don't understand the following, and would love to have more information...
