Online mode calculator

Not sure if I've posted this before, but I just made an update to this and it's relevant to this area of the forums. My online Room-mode calculator, useful for planning a listening room before you decide on dimensions.

It would be nice:
- automatic convertion between feet and meters
- xx with logarithmic frequency scale
- button to export tabular data to clipboard/file/screen

By #1, you mean, that if I enter 20 feet, then change my mind and select Meters, it automatically changes that to 6.x meters?
Tabular data is coming back, probably tomorrow.

I'm curious what you would use the log freq scale for? That isn't something I've seen used for mode prediction. Do you have a link to articles or?

#1 That's it
#3 Nice

I'm learning about acoustics. Take my view on this with a grain of salt
It's important to pay attention to modes that are alone or are too close. The hertz log scale would serve to have a better visualization on how far are the modes are from each other.
I don't see any use for the sequential mode numbering that the aplication offers. I also noticed that you present different modes at the same frequency with separate bars next to each other, ex: in a room (4x4x3 meters), I've got different modes at the same frequency: 43, 61, 172, 214, 275,286. There's no quick way of detecting this, I have to hover
