I wonder if you have seen anything like this outside the frame of a DLP projector image, in this case, an Optoma HD29Dupree:
It's darker than the black of the image but still pretty noticeable at night. Did something happen to the projector or is it just normal? Doesn't...
When doing measurements with both speakers, I keep getting strange wobbly measurement results. Please see the attached pictures.
Red green and blue and with both speakers, differen mic positions, purple is with just the left speaker.
Does anyone know what's going on and what I can...

I've been having some issues with Audyssey crossover settings lately. My current setup is as follows:
- Speakers : Chane Music & Cinema A5rx-c towers and A2.4 center
- Seating position is 10' from the TV
- Room size is 12' x 16'
- The L/R speakers are 8' apart on each side of the...
In the controls of the impules graph there are 3 t=0 offset adjustments
t=0 offset (samples)
t=0 offset (ms)
t=0 offset (distance)
1. The "t=0 offset (distance)" does not accept negative distances(with the up/down buttons)
2. The "t=0 offset (distance)" changes "-1 ft" into "-11 in"
I have recently setup my audio equipment into a new room and have taken a few measurements and the bass is all over the place.
I was just wondering if anyone has any ideas as to what is going on.
My mic is a UMIK-1. The red line is the subwoofer facing sideways at half volume level, the blue...
I am trying to measure/verify speaker delays and I'm getting strange results.
I have the recommended setup from the manual with a sound card. Right line out of the sound card goes to both the sound card left line in, and to the center channel analog AVR input. A RS SPL meter connects to the...
I have been studying REW video tutorials and the manual for days. I initially had problems getting things working but have finally made it through these steps:
Calibrated soundcard via feedback loop
Calibrated SPL, balanced mic input to match pink noise
Did the sine sweep to measure the room...

I have my soundcard's output looped back into its input, and I ran a calibration. The results are very strange.
Here's the 'SPL and Phase' graph:
And here's part of the 'Scope' graph:
Can anyone make any sense of this?
It looks like the output and the left and right inputs are all running...
We all like the big block busters, some of us like foreign films but what about those personal indulgences for the strange, the weird or cult movies. Sure they're not for everyone and I know some of your friends and family don't get it, but they fascinate us.

I'm new to the world of REW so be gentle. I started yesterday and tried to calibrate my soundcard (Creative Soundblaster MP3+). The graph I got looks OK at the begining got then goes crazy at the end, what am I doing wrong?
Hi, guys. I'm new here and tried today to use REW v5. After my soundcard (Auzentech X-Fi Forte) calibration i found that it is realy strange. I will attach my mdat file of my calibration here for you see. I think something is wrong with my sound card but until today i was perfectly satisfied...
I noticed this a long time ago and now it has returned again, after taking measurements for a few hours I noticed that in the area around 2k-20k the curve has changed quite alot. Strange because I didn't change anything in that area!!! Anyone have any ideas? Here are the before and after curves.
I just bought a UMIK-1 from MiniDSP to measure my untreated, two channel listening room with REW. The end of the 10-20khz frequency sweep (about the last second) does not sound smooth. There is a wavering sound that sounds kind of like an ambulance siren that can be heard over top of the...
I'm a new REW user, configuring 5.0 with:

S/C - TC Electronic Konnekt48 (Firewire)
LineIn (Audio routing to counteract Mac/Java Firewire issues)
Soundflower (As LineIn).
I had no joy at all until I installed LineIn and Soundflower. Now I have input readings and have...
I just assembled my first subwoofer build using my JL Audio W3v2 and a Bash 300 amp in a sealed 2cu ft enclosure. Everything sounds good and I get lots more bass compared to the previous sub I was using. The problem is I can also hear a vibrating sound coming from the driver at all volume levels...
