I was just looking at that link. John is using the UMIK-1, so that ends the USB speculation. I have not had the opportunity to test yet. My wife told me if I keep her up with test signals again, she's going to throttle me. I wanted to do some testing this afternoon, but I spent all day cleaning out our shed. So much for a nice relaxing week off from work...

Hopefully tomorrow morning after the boy gets to school, and before I my buddy comes over to start rewiring the shed.

Jim, could you change Preferences > Analysis > Impulse Response Calculation to "Keep full IR". Does that change results?

Tried that, no change.

I basically went through several settings, changed them all to no avail.

Analysis
1) Unchecking sub-sample timing adj
2) Unchecking t=0 at IR peak
3) Unchecking Decimate IR

Comms

Changing this setting to 1000 had an effect (512k measurement)

Jerry,

Have you now, or ever, had Omnimic on the computer your measuring with? I think the answer is no, but I want to be sure that the OM software on my computer isnt interfering in any way.

Verify for me again what mic you use.

In addition, could you post or link to your mdat for 128 and 1M using your main system and testing apparatus at some point?

I have never owned or used OmniMic. I currently am using the UMIK-1 on a Windows 7 32-bit laptop with HDMI/ASIO. I also have the UMM-6, but it is currently on loan to Martycool. An, of course, I have the EMM-6, which I could not get working several days ago.

As for posting the measurements, the MDAT I posted a couple of days ago was created by measuring my desktop speakers, not my audio system. I don't have an MDAT of the main audio system in which I vary the sweep lengths, but I guess I could create one.

Thanks for the info.

Since you are the only other one so far experiencing the problem, I want to have a close look at real mdat's from your main system.

OK, I ran the sweeps test for my main system. I ran four sweeps for both the left speaker, and then the right speaker. They exhibit the anomaly we are trying to explain. I also tried running multiple (2, 4, 8) sweeps of the same size (256K), and each of these measurements look different as well.

No Jerry, you dont have the problem. See how your IR match pretty well on top of each other for 128 and 1M? See how mine do not? This is the essence of the problem, and changes the probable cause significantly. Namely, the Dayton USB mic that comes with the OM v.2 kit doesnt work well with REW. At 128k, it looks decent. Beyond that seems problematic.

Perhaps Kal will get back with us. So far, he is the only other one who uses the same mic as I with REW.

BTW, there is actually a significant change between the measurements I supplied a couple of days ago, and the ones I took today.

The first set of measurements were taken using the Java driver. Today's measurements were taken using the ASIO drivers. Perhaps this could make a difference? Aren't you using the Java drivers?

I've been using the usb mic from mini-dsp. With the on board sound card I was having no problems using the loopback feature in rew for timing reference. I switched over to an asus sound card, and noticed an issue where the impulse response was not consistent. There seemed to be some amount of delay in the first measurement, which reduced with time. Life got busy around this time, so I haven't had the chance to investigate further, but the recent discussion has sparked interest again. I'll try and find some time early next week to report my problem accurately.

So is the Java driver possibly the difference we are looking for? If you asked, I bet John M is using the ASIO driver. It's the only difference between my two sets of measurements.

I gave him a screen shot showing I used Java and he didnt say anything about it. I will try the ASIO driver tomorrow. I am not hopeful though.

Now that I am the only one with the problem, and the only one using the Dayton OM v.2 kit mic, I am betting its my mic.

Is there a reason you haven't been using ASIO/HDMI, or doesn't your hardware support HDMI? Sounds like the OmniMic might be the root cause.

Java is the default setting for REW. Didn't see any reason to change it. Not sure that is your question though.

I cant get REW to work with ASIO OH well.

As suggested earlier in the thread I've now run Audyssey but all it's done has muddied the waters for me.

What receiver black magic have I engaged so that I am seeing a difference between the same full frequency sweeps, but with different speakers powered on (bare with me--I'm not that dumb)

The chain:
REW out of PC via ASIO4ALL HDMI to channels 1 and 2 to Onkyo 805 AVR
Full frequency sweeps (20 to 20000) with AVR in "stereo" mode, -30dB FS
AVR Audyssey chosen crossover of 90Hz

Play full sweep with just Sub - good SPL
Play full sweep just L - good SPL
Play full sweep just R - good SPL

Play full sweep with L + Sub, Sub stays the same, L drops by 10dB
Play full sweep with R + Sub, Sub stays the same, R drops by 10dB

Something I need to change on the AVR side? Is my brand new UMIK-1 with calibration file actually not that calibrated? Any idea what I'm missing?

Thanks. Again.

HD,

What your seeing is completely normal. The LFE channel outputs 10db higher than the other channels (as is intended).

AVR: DENON 2113ci
FL/R: Klipschorn
CC: Klipsch RC64ii
SUR: Polk LS F/X x 4
SUB: PSA XS15 x 4 (Soon to be replaced with dual T-18s!)

But this wasn't feeding into Channel 4 (LFE). This was bass-managed bass in "stereo" mode directed from the mains to the sub...

OK, let's review your measuring technique. First question is regarding the measurement level. You state you are measuring at -30dBFS. The default measurement level is -12dBFS. I don't see anywhere in the Guide that says to change this level. Why did you change it?



Next, lets review the HDMI selection. To measure left speaker only, you should select HDMI1 as the output, and you should physically turn off the sub(s). For the right speaker, the same except use HDMI2. For combined left+sub, you simply turn the sub on. You do not select the LFE channel (HDMI4, I believe). For the combined left+sub, the left speaker should be set to Small so that bass management routes the low frequencies to the sub channel. Is this exactly how you measured left+sub? If yes, there should have been no drop in output levels.

Finally, the shape of the measurement curves looks pretty good, so I would not be blaming Audyssey for screwing anything up. Let's continue to research pilot error. I don't know why you continue to have output issues. You are the first.

BTW, your sub(s) look way too hot.

When you do R+L at the same time, aren't you doubling up on bass? Perhaps one of the experts can weigh in.

On my system, when I measure L+R the level is higher than if I measure L and R separately. But HD is not saying he is measuring L+R simultaneously.

BTW, HD, you continue to confuse us by using the term "LFE" if you probably mean the sub signal. As you know, the re-directed bass signal is an entirely different animal than the dedicated LFE channel. Perhaps you could use the correct terminology going forward?

Yeah, I should have been more clear, but I was in a rush and knew someone else would be along to explain in more detail (as you did so well!). However, what I stated was completely true....I just wanted him to know ASAP that what he was seeing was normal for the output settings he used.

Is this exactly how you measured left+sub? If yes, there should have been no drop in output levels.
Fairly certain he selected HDMI1 + HDMI4 otherwise he wouldn't be seeing the 10db boost.

AVR: DENON 2113ci
FL/R: Klipschorn
CC: Klipsch RC64ii
SUR: Polk LS F/X x 4
SUB: PSA XS15 x 4 (Soon to be replaced with dual T-18s!)
DISP: Mitsubishi WD-73740

Except he answered by saying he didn't select HDMI4.

@HD: Is it possible that one measurement was done at -30dBFS, and the other one at the default value of -12dBFS? That would certainly result in a level difference.
