RPG Room Optimizer and other software rives, etc.

We sell the optimizer and sizer from RPG and the CARA. The sizer is really only for new construction to get optimum dimensions. Not really applicable for you--and I figure you already knew that, but for others reading this post I wanted it to be clear. The optimizer works well for rectangular rooms. It's pretty easy to use and straightforward. The CARA is far more flexible, but as mentioned above, it takes a lot more time and a lot more input. The learning curve is pretty steep, but the payoff it pretty big in terms of flexibility.

If you like working on the computer, doing drawings, and learning new programs--get the CARA. If you have an unusal shaped room, then you have no choice--you have to use the CARA. If on the other hand you don't want to spend a lot of time and just get some basic assistance for a rectangular room, then the RPG is probably better suited for you.

Rives Audio Software Page

Just to add to cinematic--the ETF software is fantastic. All of our dealers use it for acoustical measurements (they are required to in order to be a Rives dealer). We find it to be the most cost effective product out there. It's not the easiest to use and does have a few quirks (just visual things--not operational)--but it is incredible what it does for $150. We also sell this software and highly recommend it for in room acoustical response.

Back to the original question of CARA. I can tell you that it is remarkable how close the model and actual measurements are until the room gets very complex and then the deviation probably has as much to do with designing the room in CARA as anything else. The comparison is what has made me a very firm believer in just how powerful CARA is.
