REW 5.31.3 Room Sim Bug

[MediumRare]

I am trying to simulate two subs and two mains. When I select Reference there seems to be a bug that continually recalculates and causes odd behavior. For example, the second sub checkbox flickers and sometimes the second sub goes away in the output graph. Diagnostic file attached.

Thanks, that should be fixed for the next V5.40 beta build, which will be available here sometime next week.

I, like many others, have an irregular-shaped room. Mine is a fairly simple asymmetry that I’m pretty sure will change the reflections enough that it will make a difference in the sub placement. Any chance you can add that capability (build room dimensions as a graphic polygon) to room sim?

Also, could you add a phase shift unit to the existing time delay in ms?

No, that would require a finite element solver.

The phase shift would be frequency-dependent.

Understood

The phase shift would be frequency-dependent.

I’m thinking of the single knob that subwoofers have for integration. Not sure how they work but I bet you do It would be really helpful to be able to get a first-pass prediction of how to do a setup, then confirm with REW.
