Room EQ Wizard RTA Real Time Analysis

Steven J Stanek March 2, 2017 No Comments

I have a program opened up called Room EQ Wizard and I’m using a plug-in on there called RTA real-time analysis. And once I’ve discovered it – well, pardon me, I initially discovered it for treating room issues because it’s real time, we’re able to send a signal out of your monitoring system and you can actually move properties in the room acoustically and see if it resolves the issues.

So it’s kind of a tool but what I’ve ended up doing over the past year or so is leaving just the reference mic on in the back half of my room or in the front half or close to me in the listening position. And you have to calibrate it every time so you know as – so your measurement is correct but once you do that you can really put this microphone in areas of the room and look at your EQ. And I will put it in my listening position and check my RTA while I’m mixing in Pro Tools.

And it’s a useful feature because in Pro Tools I’m looking at possibly a mastering EQ analysis and I can see the energy in the low-end but this RTA in Room EQ Wizard is just very responsive and it’s the indication of what I’m hearing in my room as opposed to what I’m seeing in Pro Tools. And I can just make the best judgment call based on the two.

So I’m going to play a session from Pro Tools of an organ piece that we had an organ player who came in. This is with our rebuild Leslie at Sacred Grounds. And I’m going to just highlight some things that I see with the RTA in Room EQ Wizard.

So immediately I see the transient heads of harmonics and different instruments and whatnot and the reason why I like to flip back and forth is because if I need to zero out a frequency or address a frequency and I’m having trouble identifying it, I can use this RTA spectrum to show me that.

So it’s a great tool if you need to focus on say the low-end you’ll see the bass living in this area right here of about 60 to 200 Hertz and those are usually the fundamental frequencies of the bass and then above that you can see the harmonics. And it might make you – it might help you, when you’re grabbing an EQ you can focus on the frequencies right away. And these are the frequencies – it’s important – these are the frequencies you are hearing in your room which may not actually be the same frequencies you’re seeing on your Pro Tools session.

So use this tool wisely because my office which is where I’m located at making this screencast is not a great acoustical environment. When I see frequencies in the range of my problem areas I tread lightly in those areas and I try not to EQ very much in those. So when you’re in a proper room that’s flat or close to flat you can trust this EQ a little bit more for your mixing purposes so one way to use RTA in Room EQ Wizard.
