Incorporating MiniDSP With Audyssey XT32

[William Lemmerhirt]

There's something I haven't tried! Still doesn't solve any of my issues above wherever the crossover point is would it? I still need to go higher to be able to adjust anything, correct? Bear in mind I haven't ran Audyssey yet. It's currently turned off and the settings are default values. I manually rest all of the trim levels to 0 also.

Did you set them to0, or 75db all the way around ?

It won’t necessarily solve where your XO should be, but it might be useful in determining that. Since the cycles(time) changes, it’s possible that different distances will work better with different XO’s. I’m sure there’s a formula, but by the time you do the equation, you’ll have had enough time to try different settings and see what happens. I like doing that too. Then you get to see first hand what different adjustments do. That’s surprisingly one thing I liked about using my trusty old BFD. You had to kinda immerse yourself in it.

I'm ambivalent about adding the color grading. It doesn't add any new info to the viz and adds another dimension for confusing the observer. Notice the color grading is dependent on choice of vertical scale. 85-25, 75-15 and 75-15dB respectively. Right away, first's colors can't be compared with the second and third, yet, rest of the waterfall data can be.

That wasn't my choice, after updated to 5.19 beta 7a, that's the default setting. I was too lazy to change it.

Back to basics. Give me a boring monochrome waterfall.

Boring monochrome right here:

Is it me or do these graphs have a bit too much resolution? All these sharp peaks troughs are not perceptible to the ear. REW will allow for more realistic rez.

1/6th is pretty close to what we hear. I THINK! Not sure for waterfalls...
Hmmmmm

I guess I’ll speak for myself and say “I” can’t hear high rez. 1/6th makes better sense even for waterfalls.

 

[Mitchibo]

And I don't know how to change it!

Oh! There it is... a couple more graphs.

This is both subs and speakers together with filters from REW. I haven't done anything manually or run Audyssey yet. The crossover is set at 150hz for this particular sweep. I just wanted to change the color and show a much improved waterfall and Spectrogram. Turning off all the noisy stuff in the house helped for sure.

This ain’t bad. Looks fixable. Bump at 54, gap at 75. Welcome to my world.

Put some effort into it this afternoon and this is what I have right now.

It's getting a little late so I'm done for the night, but I left my stuff out and plan to hit it in the morning again. I really didn't adjust much manually. This is mostly Audyssey + mini. Straight stereo, no DEQ. No smoothing. Crossover is 120hz. I didn't touch anything above 90hz.

Tits

Ive been lookin!!! All I can see is one long flat tit...weird
Looks better than ever. Man I wish I had XT32. Oh well. Some day. I do however have useful extension to about 15hz, which is cool. I just watched http://www.imdb.com/title/tt1355644/
Passengers, though which looks like it has a 30hz shelf on graphs I saw at DB, so whoop dee do. Dumb...

Is it for subwoofers only or with some other speakers? If it is for all channels including subs then we have very similar result and I highly doubt you can do much about the remaining dips. Bumps you can fixed with the mini but not large sharp dips. They are likely narrow enough not to be noticeable but I am going to try acoustics panels anyway, as I can't move any of them any more.

I spoke to SVS about this before and they too, recommend using 1/6 for the FR plots.

That is both towers and both subs. Just how I'd be listening to music.

I'm sitting here looking at my measuring equipment and wondering what more I can do. It sounds freakin' awesome! I think you're right, there pretty much isn't much more I think I could do at this point. I might pull up last night's and apply some smoothing. 1/24 or 1/12 smoothing? I see you guys are talking about even 1/6 smoothing.

From 15-100 Hz, I have yet to see a better looking one. You can try all kinds of things but I highly doubt you can hear the difference. Room treatment may improve the higher frequencies though.

Did Floyd's book say anything about those narrow dips?

REW generated some heavy filters, but more of them were - than +.

This is what I did at the input channels. I did just a little bit of tweaking manually. Just a couple of frequencies. This was the final touch after running Audyssey.

After running Audyssey I was able to improve it a little too with minidsp. It is really a matter of bang for the buck, I mean, can you really hear the difference with those very minor tweaks.

Again, did Floyd's book talk about whether those very narrow dips are in fact audible by regular people?
Is that book (3rd edition) available in PDF, or hard copy only?

As far as I know (limited knowledge) large, boosted dips just present other issues. If it’s brief, live with it. It’s likely just a placement issue. Captain obvious here. Toole would concur. I personally like to push and pull fq around so as to see and hear immediate response from EQ’s. Toole’s great for theory but there is enough experts on this site to handle most issues. The plus of messing with it yourself is demonstrably better than looking for that magic bullet in scientific journals...that is, for those of us w/o sound engineering degrees. IMHO.

Post 1/6.

I just loaded up last night's adjustments and did 1/12 smoothing. Just now saw your post.

Like I said, I didn't touch anything above 89hz. That big dip at just over 100 bothers me...

Here's what I started with.

That's with both speakers and both subs before applying any DSP, REW filters or running Audyssey.

I guess I did adjust above 100hz. Turned a peak way down. Maybe I should look at that one again...
