I think I found a bug (or I'm not measuring correctly...)
When I measure with 2 sweeps and looking at the Impulse response graph it seems that the second measurement is delayed by 0.23ms, causing two spikes everywhere instead of one. When using 1 sweep I don't see this behavior.
Making some experiments in my room with REW (5.01 beta 21) I found a strange behaviour.
In the All SPL window, the Trace Arithmetic functions seem to give wrong results.
See for instance the plot here below.
The green and blue lines are two measurements while the red line is supposed to...
I am trying to run REW 5.01 beta 17 on a Mac running OS 10.6.8. I've looked through many of the threads, but frankly there is so much here that it's a bit overwhelming. I'm getting the following error message when I try to launch:
Exception during startup
So after playing with REW and my RS SPL meter as a mic, I decided to get an upgraded mic to see what was really going on so I ordered a CSS Umik Mic.
The unit arrived last week and connected up pretty easily. My calibrated mic is down 1.8db at 8hz so pretty happy.
Here is my room...
Maybe Im doing doing this right... but the Mini-DSP UMIK-1 does not auto detect. I was able to use it to make a measurement, but the prompt shown in Mini DSP web site is not working... and I dont have my calibration file :-(... I hope they are able to get it.
Room EQ Wizard Version 5.01 Beta 13 Release
Beta 13 changes (20th Jan 2013):
Beta release now supports OS X (tested on 10.5.8)
Order of measurements can be changed by clicking on the currently selected measurement in the measurement list and dragging it up or down to a new position...
Unsure where to post these, or check if they have already been posted anyway here are some bugs I have noticed.
I at least cannot find a way of removing the smoothing I had set in the preferences. Changing the smoothing or using Graph->Remove Smoothing still shows the graphs...
I'm a new member and just bought gear to perform room acoustic measurements, however i seem to be stuck already in the soundcard calibration phase.
