**Please note: at 4m40s the proper Delta value & delay time is 20ms. The plugin used in this video is an early beta version.
in soviet russia, you do not find delay, delay finds you
And you owe it money...
i guess Im asking randomly but does anybody know a tool to log back into an Instagram account?
I was dumb forgot my account password. I love any tricks you can offer me.
@Layton Dorian instablaster :)
@Jad Brayden I really appreciate your reply. I got to the site through google and im in the hacking process now.
Looks like it's gonna take a while so I will get back to you later with my results.
@Jad Brayden It did the trick and I actually got access to my account again. I am so happy!
Thank you so much you saved my account :D
WOW, I'm not ready for this. Lol
VAL!!! Its been ages since I last saw you!
I am totally lost ...you can you all this this smaart already .... then why bother using the plugin ???...what I am missing here ?please answer anybody ....thanks
You can make a TRAC makes FIR filter for you. You dont need to spend the time butchering your eq to get the results.
Keep in mind that you still have to have good coherency on smaart before capturing for averages.
Trac works through the API feature of smaart to share the data to Trac
Love your videos
And what about coherence? If you have a uneven response like in the video, you also need the coherence to make a solid interpretation of the measurement. It is totally wrong to stupidly create an FIR-Filter that compensates a Measurement with low coherence which is of course corrupted by a lot of factores (for Example reflections of all kinds)
Isn't that why you need SMAART integration?
I'd like he's "have a great show"
Thanks wery usefull knowledge
Amazing
How can you do all of this without having smaart?
Thank you for this lesson.
What we would really appreciate is to see the response after the processing is applied and you don't do that in any videos... Isn't it what it is supposed to do? Why not show it?
I don't need this but this video was very interesting
Wave audio rock!
Мега мощь !!!)
So it's like some kind of automated processor ? It seems it can replace everything we usually do using a processor on a sound system (delay compensasion, eq for the room, and even compressor if we use other plugins)
Except someone has to know how to set it up, how to plan for and compensate for less than ideal presenters/musicians….they may be able to replace some of what we do with machines and software but in the end, what we do is art and that requires a human to do….i have zero qualms with a piece of gear that will handle any feedback issues that may popup as long as it does it in a only when needed sort of way, like a dynamixc band versus using a parametric that always present in the overall mix
Very Good
Hey Waves, hope all is well. What is the spelling of this kind mans name? Is it Vaal or vel. Just enjoy his presentation every time with his accent. Hope he keeps presenting more videos for Waves.. Thanks for sharing..
Shouldn't the Delta at around 4:30 in the video be 20? As in 36.29-16.29?
see note in the video description:

Thanks god i found this comment. I spent around an hour trying to understand why the delay time remain 16.29..
its truly almost blew my mind
si tu passe pas tes sub en full range pour dire au logiciel ou sont les sub par rapport au micro en impulsionnel et ensuite regardé la phase ,ta phase est faussé. Sauf si les sub sont collé,la sa marche.
yeah, let´s correct it exactly in the high frequencies like shown. probably there will be a little problem with Sibilance in the vocals ( and much more )
Sorry, tuing a PA is not that easy and will never be. The Human part is still there to NOT do it with a simple stupid auto correction curve!
The older mixers know that, but the younger genreration wich is used only to plugins and digital?
exactly my thought...would have been easier with cuts at 125 (which the plugin misses completely), 500 and 2k and a small correction at 14k
Shrike, I hear you, with all due respects to the engineer [I wasn't there btw] that resultant green curve shudders me with it's boost around the 160-200 mark, always areas where I have always attenuated when tuning live PA systems, just saying.
@@izzieschitzenberg2335 Agreed, i have never had to boost that frequency range ever in my life, it's always attenuated
X&
It'd be great if he went through hookup also
Some "bumps" and "dips" simply shouldn't be equalised. Blindly flattening the magnitude response doesn't solve the whole problem.
I think ,if it creates eq what we want ,then its helpful
@@justahobby4 The probability of room creating the eq that we want is extremely small, the opposite is quite possible. but nevertheless, these problems are often simply inequalizable.
@@olegnaumenko4871 without eq ,ya its not gonna happen
But with eq Its posible,may be sometime we want louder speaker for that purpose
Smart,dirac live apps ,rew how about liencese and price .
How you setup with Waves MultiRack? Please !
I never boost frequency between 250-400hz i usually attenuate, thats where's all my boomy kick sound lies...just sayin tho 😬😬
Who eqs before time aligning? That seems counterintuitive, how can you eq when you may possibly have phase issues due to time alignment. Does anyone else delay their PA to the kick drum/bass amp?
Not only counterintuitive, but totally wrong. First of all, mechanical alignment is needed.
@@PeX218 im sorry, my brain is a lil fuzzy from last night, are you saying im wrong or our dear Russian friend, or heavens forbid, both of us.........im still trying to wrap my head around some of Owsleys statements concerning eqs and how everyone except him does everything wrong when they use an eq
@@ericclinton7399 You're right.
@@PeX218 you are too kind......you should read Owsley’s notes and theories on eqs, they seem so wrong but......he was Owsley
On which link to I find track?
So difficult
In the Seventies and eighties we used a radical system, our EARS.
I still do the 31 band and a OSC if i have a young crew just to try to teach them some of the old Skool.....ever hand them a roll of butcher paper and a pencil and ask them to do the rf intermod calculations for you? It starts out funny when they dont understand why the pencil and paper, then gets hilarious when you explain how many freqs they will have to check for and then downright hysterical when they ask what the formula is and you explain for every freq you need they have to run it against every other.......you can tell when they've finished doing the quick math in their heads and realize how many times they will have to run thru it for just 8 mics......i save that task for “ Mr or Ms I know everything/My cellphone is more important than doing my job”
@@ericclinton7399 I'm interested in learning more about this and how to do this. Is it better than SMAART and how well does it work if you do the math right?
Yeah...
Step 1 where you measure the response of the venue is already misleading.
You want the response of the venue as heard by the audience, and NOT only the mixing seat.
It might make more sense to capture an averaged response from a field of mics, scattered around where the audience will be.
Great, so after you've tuned your system for audience positioning (room response) and time-aligned, then you have to account for when the audience is actually present. As we all know, a crowd of people will damp and attenuate signals, as well as reduce SNR, though on the plus side they help scatter room modes. From this point, you can pick your poison for coping with the audience.
Maybe use a preset to estimate damping, for various crowd sizes (this method is static and sort of dumb).
Or maybe keep field mics in place and use signal coherence (with averaging) to estimate how source-to-receiving transfer functions change under the presence of an audience. Now we're talkin'!
It’s his choice where he measures as long as you take into account that not every place will be in alignment. If you measure in the audience area, your FOH can end up in a null. It’s what Bob McCarthy and Merlijn Van Veen refer to as a democracy vs a monarchy. One way or another it is still a compromise.

sir, what is the name of the mic used to measure in this video? What's the brand and mic series? Thank you sir
its just a omni directional mic my G earth works makes a really nice one!@!!!!!!!!!!
Audix TM1
But you're better off getting the iSemCon EMX-7150 with the spl calibrator.
Are you kidding me you call this a step by step video, cmon waves
I'd like to see how does tract handle measurement problem like ground/wall bounce or comb filter from several PA source? I always used tract in mono to avoid it but how could does it play in stereo?
😊
for cost of PA id expect this to be bundled lol
“now your frontfills are time alligned to the mains” Really??? :-)
Yes, but only at a very defined distance from stage, at the point where the microphone has been during measuring - a couple of steps back or forth and you´re out of time alignment :-)
@@gertrickmann-wunderlich8203 That is the same with any component of the PA system. Everything is a compromise.
Just use fletcher munson curve on eq and you're done, no need for this computer 😅
But you need to know the response of the PA before inserting any EQ.
how we avoid feedback destroyer
with that phase and frequencie response between PA and Subs the responde will be comb filter dont do this never
i can't get any captures in smaart. I'm not seeing level when doing the spectrum captures. i have ins and outs set right. i see level in the small meter on right but nothing is getting recorded. any ideas?

Sorry, the answer was meant for another question...
Is TRACT able to create an average curve out of multiple Smart captures? Given the fact that you usually have a quite wide coverage with a soundsystem I find it inconvenient to use a curve used from measuring one point in the audience only.
I'm guessing you could use the approach at around 2:08 in the video out in the audience instead of just near the FOH.
yup. just like at 2:28 -- looks like you can merge captures from various measurement locations into an average, and use that for the calculation
the question is if it has the phase coherence function... ;)
oh dear.
А можно сделать эту обучалку на русском?
the delta value at 4:41 is correct?
see note in the video description:
