Once I improved my modal ringing/decay times, my ETC, group delay, comb filtering went away, things tightened up, and my system now sounds as good again as the difference between no Audyssey and with Audyssey. It is truly refined now and that just cannot happen without measurements and understanding them.

This is one of my main areas of interest too. I have treated my room and the result is terrific, but I would like to learn more about verifying the results I am hearing.

Absolutely!  It is so reassuring to know that help is on hand, especially for people like me whose Window skills are now almost zero (it's been about 10 years since I used Windows regularly). I do like the idea of plugging in the mic, then just one HDMI cable and being good to go!  That is even simpler than setting up OmniMic (no need for the external test tone CD).

I just ordered this one: http://cross-spectrum.com/measurement/calibrated_umm6.html

They are on back order, with a shipping estimate of late January.

Do we need a new thread for Audyssey aficionados exploring new REW capabilities?

The analogy that comes to mind when I compare even the easier to use (hopefully) REW and OmniMic is Microsoft's early attempts at Windows versus Apples intuitive user interface.


Just sayin'

IKWYM. As someone who has used Macs for years and years now, I still shudder when I recall my dark days of XP, and before. HST, REW is available for OSX as well though...

Sorry for the OT meandering!!!

Yea-I've used Mac's since Sept-1984, here is my 128k mac during college years, and my MacPortable during 1992.
(with $1k USD for 3MB static RAM module back in 1991 for 4MB total RAM)

I've never owned a pure WinTel machine, do have VMWARE fusion on my 27" iMac.

I'm also hoping some of the REW WindowsBETA v5 features move to the Mac v5 soon....

Great deal!
I got my calibrated ECM8000 from Herb....since my gear works hard to justify another mic (I have an un-calibrated ECM8000 also....)

I may well order the same mic too. Late January will give me some time to get to grips with some of the principles. If REW works out for me, I would expect to get a good price for my OM kit, but I won't be rushing to sell it.

 

I think a separate thread for "REW for Audyssey Users" would be a terrific idea. I nominate Jason as the Thread Starter as he is very knowledgeable in this area and also so extremely helpful.

+1 totally agree, thanks to Jason easy plug-n-play post and all the questions and answers by Keith, Batpig, Feri, Mike, Jeff and others. One of my new found resolution for 2013 is to relearn and rerun REW after reading the last three pages tongue.gif.

Thanks AVS gang and Happy New Year all!

Inevitably, I have now ordered the mic. About to download the beta of REW...  is that a rabbit I see before me - I didn't know they came so deep....

+1. With more focused thread it will be less noise in both threads after all. And it will let people who are interested in the details and measurements to talk about their results and ideas without disturbing everyone.

+1 on a separate thread.

Here's a question. I just purchased OM and I'm still within the 45 day return from PE. I may have a restocking fee and return shipping (need to check). Should I keep it and e-bay it later once the dust settles on this new REW setup or send it back now?! I did get a free tripod (not the greatest but works) so that could offset some of the loss if I keep it. Thoughts?
post #58602 of 70900
Questions:
Before downloading V5.01 beta 10 do I need to delete the old REW version?

After V5.01 do I still need to download ASIO4ALL (the one Jeff posted)?

So REW connection will be:
UMM-6 -> usb -> Laptop -> HDMI -> Receiver -> HDTV
post #58603 of 70900
Hello guysnewbie here i have denon 1612. I have a question. I have spl meter tool, but i dont know how to use it. Do i need to run the audysey first and then tweak the speakers by using the spl meter? How to use spl meter to tweak the speakers? Thanks. Happy new year.

Difficult call. I have the OM and am very happy with it. I never considered REW until Jason pointed out the new simplicity in the latest s/w along with the much simpler hardware setup needed. I have always thought that REW was a superior tool, but its superiority, for me at least, was counteracted by its complexity of both setup and use.  HST, OM has given me a very good grounding in measuring which I would never have had otherwise - the  experience I have gained with OM will stand me in good stead if/when I convert to REW. You might care to keep the OM and gain some experience with it and then, if you do decide to convert to REW later, sell the OM on. As it seems the sole expenditure for REW is now less than $100, you will probably be able to move on at zero cost, as I would expect you'd get a very good price for an OM kit in 'as new' condition.

What is it you want to 'tweak' after running Audyssey? Usually there is no need to tweak the level settings that Audyssey has selected - arguably Audyssey will set them more accurately than a regular SPL meter will.  Have a look at this section of the FAQ and then come back with any additional questions you have...

J see. Im just only wondering if i can tweak all of the speakers after the audysey. Like i will set all the speakers to 72db for all of them. I dont know if that is right to do or not. Thanks.

Audyssey sends out test signals in order to set speaker levels to 75 dB SPL at the Main Listening Position. If you turn down every speaker by 3 dB after Audyssey you will no longer have film reference level at 0 dB Master Volume setting, but at + 3dB. Nothing wrong with that, just not practical.eek.gif

For me, REW has some pluses: (1) ability to measure each channel independently with an HDMI connection and (2) with a single measurement get various measurements results.(3) test signal built into the program The primary downside is the restriction to only measure to 15hz.

But I have ordered the mic. :-)

I think HDMI is not enough. You need to check whether your laptop is capable to perform 8 channel output with ASIO4ALL. In Preferences -> Sound card tab you need to click on ASIO Control Panel and select an 8 channel "device".

In my case with a Toshiba A660-1EU laptop with i5 microprocessor it is the Intel Graphics card's sound chip that shows 8 channel support, while my other choice would be the Realtek sound card which only shows 2 channel support. Please check to be sure.

On a second note, hopefully a newer laptop with HDMI will be able to support 8 channels, but still worth to check.

Not necessary, the newer version will overwrite the older version, but you will be prompted, just say YES!

Yes. Then go to REW ->Preferences->Soundcard and look for the big radio button: "ASIO Control Panel", it should be there. smile.gif

It seems like a logical next step--if you view audio calibration as an evolving body of knowledge, especially since so many FR results may 'sound alike'. I for one would be interested in accessing tools that can get the most from my speakers, and tune on-axis performance. Not sure if I can add much room treatments due to WAF, but educating myself in what the room does to sound is something I need to move beyond the 'informed caveman' stage.

Another +1 on the REW for Audyssey users dedicated thread, and I'm ordering my own USB mike to use with REW in the next few days. If nothing else, $100 is a minor investment for moving into a more rigorous assessment.
post #58615 of 70900
Apparently my exuberance was over done. I have attached a screen print from the ASIO driver and no option for 8 channels was available. Have I done something wrong or am I just SOL ?That sucks!!

On the ASIO Control Panel click on the "+" sign to expand. It will show how many channels are available.

And quite pointless, imho.

Well, I'm intrigued with being able to test 8 channels, which is why I went ahead and ordered the USB mic.  But with the "old" method, I could individually test front left, front right, center (setting mono signal configured as PLII Cinema), and the subs.  TBH, measuring the surrounds, heights, and wides is not likely to produce very meaningful information.

 

What is the 15Hz limitation you meantion?

Why do you think so Jerry? Aren't all speakers in the system equally important as regards overall SQ?

Equally?  No, I don't think so, Feri.  I think the left and right surrounds are quite important, but the back surrounds, heights and wides are lower on the "importance" scale, IMO.  I use measurements to help place speakers, for example, and I have very little flexibility with regards to the placement of my surrounds.  My fronts and center are very carefully placed, with the help of REW measurements.
