Re: CARA Forum

I have never tried that, from what I can tell it is hard-coded.

Yeap, it is. And no upgraded versions of CARA during last 6 years ((.
What kind of programs are you using to calculate RT60 at listening room?

Re: CARA Forum

Cara isn't bad if you have the time to just let it run. The only problem with it is that it uses ray tracing in order to calculate the response of the room. This is fine, but the calculation time is enourmous since you need to factor in one value for every single boundary, as well as pieces of furniture resulting in a calculation time that can take months...literally. As an experiment, I attempted to run a calculation using 8 reflections on a dedicated computer. I decided to stop it after 5 weeks. Yes, it took five weeks just to get that far. Yikes! Minimum calculation value with any accurate results would be 6 in an empty room. Anything over 3 or 4 boundaries results in the increased exponential time factor. Unfortuntely, anything less than 6 for a rectangular room is not accurate.

Re: CARA Forum

In the hope of re-activating this thread, i would like to add my post. I have used CARA in the past and plan on using it in the future. Therefore, i was hoping to find an active forum for CARA users.
The last post here was 5 years ago, but hope dies last...
Also, it really would be awesome, if there was a v3 of CARA. It desperately needs multiprocessor support
