Your decay below 30hz, while higher than the rest is still to be expected somewhat. Nothing over 300ms above 30hz is also pretty solid.

I am having problems with Omnimic. Everytime I start the software, newest version, I get an error message: Runtime error 217 at 000284BA. I tried running the program on a second compter and get the same thing. Virus program, Registry cleaner and repair have been done. Also, the antivirus software was diabled to see if that was the cause.

Parts Express has no ideal of what the problem is and escalated to a higher tech. Any help appreciated. Microsoft thinks it is a software issue with the Omnimic program.

Go directly to Dayton Audio and contact Bill Waslo, the developer of Omnimic (and lots of other stuff).

I think that is who they are contacting for the problem. I just wonder if anyone else is having the same problem?

Apparent Omnimic fix in Windows 10 for Runtime error 217. Right click the app, go to properties. Then hit compatability mode in the top right corner. Select Windows XP serice pack 3 and hit apply/OK. I did this and at least got the app open. Now I just need to get the mic back from PE to see if this works.

Yes, they sent it back. The fix was to use it in compatability mode for windows XP 3 if I remember correctly. I don't seem to be able to get a good waterfall graph in the bass region. The bass decay works fine but, I need to figure out the waterfall.

Here are some graphs of the house curve which is on the aggressive side.

I have been meaning to update my laptop from windows 8.1 to v10.

I see derrick had an issue.

Should I just stay on 8.1?

Yes. It did not initially so maybe Dayton did something. It work as intended now. Omnimic is still the easiest system to learn and use without a lot of fuss.

Anyone interested in a brief tutorial on Impulse Response how-to.


my goal is to map out first reflection points.

Ok sorry, I didn't realise the Dayton mic had its own software. I presume the impulse response graphs look similar to REW though?

I don't think the impulse response is that important in a multichannel room. Get a mirror and someone to hold and walk along the wall.

I should be able to measure the room, and show the improvements. I'm aware of the mirror test to find the places, but if the absorber isn't measuring an improvement, what really have I accomplished

I used track #3 long mono sweep, there are 3 peaks i can see, are there actually 3 reflective surfaces reflecting back to the LP?





Thats for another thread though, building a proper broadband absorber, and measuring the improvements

I have found this a difficult function to use. It can give a global picture and localize some problem to the left or right, front to back. In a multichannel system, multiply each speaker on all the available boundaries. One speaker in a rectangular room has 6 boundaries. Now let's go to a 7.X system and you have 7 X 6 or 42 refelctions coming at the MLP. All the speakers are at different distances and interacting with things on the left and right, front and back of the room, this is a nightmare . Now take this to an Atmos system with 11 to 13 sp to sort this out you need to be a mathematician.

We are mainly focused on two things in the small HT. FR and phase relationship, this will makes or breaks the system. I depend on my Pioneer Elite SC 99 for FR and Full Band phase control to a large extent and concentrate on the FR corrections in the subwoofer passband. This is usually no more than 2 or 3 filter adjustments.

I also rely on knowledge of the most common room locations to guide my placement of room treatments. I also use the available room furnishing. This keeps the room aesthetically pleasing without covering all the surfaces.

This simple method along with analysis of the bass decay function have been pretty rewarding. I'm not saying it can't be done but, no use in having auto EQ if you can't count on it to do some o f the hard work or you need a different auto EQ. This is much easier in a 2 ch system (use of ETC). Even mastering this technique has a steep learning curve.

Maybe Bill Waslo will weight in on some advice for a HT setup.

No doubt its alot to take in, but as with this hobby, ya have to break it down and take it one step at a time. Im gonna work on the main LCR where most of the trouble begins inregards to reflection. I believe the details and intelligibilty is about elliminating reflections up front, hence my belief in a LEDE theater.

I think if the software is showing correctly i have enough to keep me busy. I will begin building some absorbers for key points and not covering the whole room Lol. I hope it can be achieved through spot absorbers and not blanketing surface area's......

If anyone has used this type of measuring please chime in :0)
