♪♫♪♫.............[Music Playing] The next thing I'd like to talk about is a new feature that we added about a couple months ago with the StudioLive and it is a part of Virtual StudioLive and it's the integration of the SMAART Spectra Tools. So what is SMAART? SMAART is a really great sound analysis software that's created by a company called Rational Acoustics. And when we decided that we wanted to give our customers the ability to be able to, you know...give them some software tools to be to be able to look at the sound and enhance frequencies really well... we contemplated creating our own application. We actually do have some RTA tools in StudioOne, but if you're in the live sound community, Rational Acoustics and SMAART is really the industry standard. in this type of technology. So, we partnered with them and we integrated SMAART directly into Virtual StudioLive. So the first iteration of this, looks kind of like this:

If I go to the graphic EQ page, and again, with my mixer, the 24 channel mixer has 8 graphic EQs that you can assign to any of the Sub-Groups, Master Fader, any of the Auxes. You have a couple of different software tools available. So let me go ahead and just turn on some music here, so we can hear the sound and I'll show you a couple of the tools. [Music begings playing].....So what I'm doing now is I'm just playing back some tracks from StudioOne. We're going to open up the Master Section right here and we're going to put on the RTA. So essentially...and of course right when I do that the song likes to end... so I'm going to go back and put this back on. And let's go ahead and kind of look and see what this looks like. [Music comes back up] Okay, so what you're seeing here is a graphical, 2-dimensional kind of image that's showing you what frequencies are louder. So basically, it's overlayed directly over our 31-band EQ.

As you look at the EQ across you'll see each one there's a fader basically, or a meter below each fader of the 31-band EQ and it's showing you what frequencies on a particular thing are loudest. So let's say if I want to Solo something....I'm going to go ahead and just Solo an acoustic guitar for a second, and just listen to it....Here is "acoustic"... and we'll go back to our page here in...Here it is. Let's look at this acoustic. [♪♫♪♫ Acoustic guitar sound comes up] So what it's showing me basically is you can see where the fundamental frequencies are and what I need to kind of roll off. Because that's a big trick with mixing.

A lot of times you have an instrument like an acoustic guitar that has a lot of low end but there's only a certain amount of usable low end that you really want in the context of a full band mix. What happens is that as you see this, you'll see that there's a lot of low frequencies that are just barely coming through. But what that's doing is it's actually robbing energy, or it's robbing headroom from the system. So what I can do is I can use this RTA to analyze individual instruments to be able to see where their fundamental frequencies are. So let's just look at this acoustic again...♪♫♪♫ [Guitar music comes back up]... Okay, so really there's really not a whole lot usable below 80 Hz. So what I can do then is I can select that particular acoustic guitar, go to my High-Pass filter. What does a High-Pass filter do? It allows the highs to pass through so it basically gets rid of unwanted low end. So I can basically roll off everything below 80 Hz. So now it's cleaning up the sound. It's allowing me to get the fundamental frequencies represented but not all this unwanted low end.

A lot of times people will ask, "How do I know where to set the High-Pass filter?" Well, open up the RTA and check it out and see kind of where the fundamental low end of that instrument is and basically, all of the stuff that's kind of way at the bottom, start rolling off from that. And then of course use your ears. That's the second thing. So that's one tool that comes within the SMAART Spectra. The second tool is called the "Spectragraph." What I'm going to do is I'm going to go ahead and flatten this EQ for a second. And we're going to put the Spectragraph back on.

Now the Spectragraph is a little bit different than the RTA in the fact that it not only shows you frequency and the actual amplitude of that frequency, but it also shows you timing. Meaning, you'll see it kind of scrolling. When you first see the Spectragraph it looks kind of strange. It looks almost like Doppler Radar. You see a bunch of greens and blues and oranges. Well, the way to read that is almost like you would read a Doppler radar. The brighter the colors, that's where the loudest frequencies or the most energy is.

So one of the applications that the Spectragraph is really great for is for finding and eliminating feedback. So, everybody's heard feedback. How many of you have actually "seen" feedback? This is a really important thing because being able to identify what frequency is feeding back is extremely important because the blink reaction when you hear feedback is you just start pulling frequencies down. And you think "Oh, that kind of sounds like a High-Mid, but I don't exactly know where it is." So I just start pulling all of the High-Mids down. Well, what that does is you start eliminating frequencies that are not the problem. And then all of the sudden [covers mouth to muffle voice] your monitors sound like this. You know, real muffled and you kill too much.

So we're going to do a little mock experiment here. I'm asking Justin to act like our mock preacher here at The Ring today. One thing about the pastor here, Josh Causey that I know about, he, like a lot of pastors likes to walk out in front of the speakers and get close to the congregation at times. You know, when he wants to make a point. Well, what happens when you bring a lavalier mic that's omni-directional in front of the speakers? Feedback.

So, what we can do is we can actually go ahead and kind of set up a...[Justin's voice]...You have the Firewire engaged... Check 2, 2, 2...[Rick] One second, hold up...

Okay, there you are. [Justin] Check One, Two, Hey, Hey... Okay so this is where I would stand. Check One, Two, Hey, Hey... Hey Two, Hey Hey, Hey Hey

[Rick] Okay that doesn't sound too bad. Now you can see the Spectragraph as he's talking. [Justin] Hi everybody, I'm Justin. I am going to create feedback.

[Rick] So now I'm going to crank it up and as I crank it up, [speaking to Justin] start walking out to the front let's see...[Justin] Check One, Two, Hey, Hey, Hey Hey, Hey, Hey, Hey, Check, Hah Haw... Hmmm, Hmmmm [feedback begins coming through the speakers]

[Justin] This is the "no go" zone right?

[Rick] Okay, so look at that line that we're seeing [Justin's voice continues in background] [high-pitched feedback comes through speakers]

[Rick] Okay, we have a couple of frequencies feeding back.

[Justin] Two, Two, Hey, Hey [lower pitched feedback comes through speakers]

[Rick] So now I'm going to go over to the EQ and start pulling some of this stuff out. Now, another trick is to actually boost the frequency to make sure that's the one feeding back.

[Feedback gets significantly louder] [Rick] Oh that's definitely it.

[Rick to Justin] Okay, keep talking...[Justin] Check Two... Hey, Hey, One, Two...[Rick] Yes, I hear something up here. Let's see if this is it. No, that's not it...[Justin continues mic check] Check One, Two, Hey, Hey. [Rick] Ah, look at this white line right here. And there's something up high I'm hearing. [feedback increases] That, right there.

[Justin] I thin he's having a good time doing this. Check One, Two, Hey, Hey... Hey Two...There's something kind of low.

[Rick] Yes, I hear it. [Justin Humming the pitch of the feedback he hears]

[Rick] This guy right here. [Justin sings the pitch of the feedback he is hearing] [Feedback comes up, Rick continues speaking} Now we can just kind of take that out too.

[Justin] Check One, Two, Hey, Hey...Better. [Rick] Pretty good huh?

[Justin] A little better. [Rick] A little better. Now, here's the interesting thing about this, obviously this EQ is not going to work for the band. But it is going to work for when the pastor comes up to speak.

So what I'm going to do is I'm going to go over here to the browser, and I'm going to hit the GEQ and I'm going to create a Preset called "Pastor's Lav," which I actually already have, and I just hit this "+" button, and it says "Overwrite the selected Preset?" "Yes" I can do that. Then it asks you "Where do you want to create it from?" I'm going to create it from GEQ 1. So the basic setting on this EQ is, let's say it's flat, well, when the band's playing that's what it looks like. As soon as the pastor comes over, I just click and drag this over and there it is. That's my "Pastor's Lav" Preset. Now if he walks in front of the speakers it's not going to squeal. That's a pretty cool little trick. So that's the Spectragraph and the RTA, some really cool analysis tools.

Now, the other thing that's coming up, and this is really, really exciting, is we have the Phase 2 of the SMAART integration for the StudioLive that we're going to be introducing literally in a couple of weeks. It's in final BETA. What this is, is basically this will allow you to hook up a measurement mic straight to the talk-back input of your StudioLive mixer and you'll be able to actually see pink noise being generated through the system. The SMAART analysis is going to give you a frequency trace of your room and you can actually visually EQ your room and flatten it out. The advantage of doing this is you're taking care of some natural anomalies that are in the room. Now many of you that are in churches that are older buidlings that were not really designed...This is a...How old is this church? Anybody know? [Voice from back of church] [Rick] 70 years old? 70 years old. So they weren't exactly thinking about a Rock 'n Roll worship band with a big PA 70 years ago.

So obviously this building is not designed necessarily with that type of sound in mind. It was probably designed with piano and vocal kind of tuning. So the idea with the SMAART analysis is you're actually going to be able to shoot the room. Now the real cool part about this is that the SMAART software itself is very heavy duty, very complicated, very comprehensive. What we did is we took the technology but we made a very, very simple wizard that basically walks you through it. It tells you where to plug in the mic. It tells you where to position it in front ot your speakers. And we're going to be creating a lot of video tutorials as well. I'm sure it will probably wind up as another CCI Webinar when this is released.

If you are a StudioLive owner you're going to be able to get this as a free download. It should be available. It's actually in BETA right now. I used it all last week. I was on the road last week in Europe and we did 4 events and we used the new implementation so really exciting stuff. So that's coming. ♪♫♪♫.........[Music Playing]
