Using Pink Noise and the Built-In RTA to Ring Out Your Room

[Metrosync]

0:54 Getting the most basic information wrong here from the outset. Pink noise is not equal in amplitude across the frequency spectrum, that's white noise. The amplitude of pink noise halves for every subsequent octave moving up the frequency spectrum (or doubling of frequency), and therefore sounds spectrally flat. On the contrary, white noise sounds biased to the high end due to the fact that it has equal amplitude across the entire frequency spectrum and frequency concentration doubles for every octave you go up the frequency spectrum. Therefore, cumulatively there is twice as much energy at equal amplitude in the octave from, say, 1-2 kHz than there is in the octave below from 500 Hz-1kHz, despite the fact that these two frequency ranges both define the same musical interval, only an octave apart.

Nice video. Many in the comments are getting confused because it says "ringing out a room" but it should be called "eq out a room to be more even" ringing out to some means "getting rid of feed back issues" but this is great. Thanks.

For a newcomer to digital mixing i thought this was a very good introductory session. At least now i know what buttons to push to go where i need to go :). Thank you.!!!

I like to do any room/speaker correction on a matrix, not the LR. Sometimes I might have multiple outputs, or want to get a more accurate recording to USB, and it's also nice to have the LR insert free for something else (like the Combinator!) Also remember that you're only tuning for a single listening position here (there are infinitely many). Take multiple measurements if you can, and use your ears too.

Thanks for sharing.
One thing I'm wondering is something that gets mentioned a bit which is that won't the measurement be different in various spots so you'd only be tuning to that spot? And wouldn't it be more ideal to do an averaging of several prime spots? I understand this video is for tutorial purposes on the X32 and it's very good, but I'm just trying to work out how you might implement averaging various spots.

Such a good way to EQ your rig, many thanks.

Absolutely awesome. I have watched lots of Drew's YouTubes and always am learning from these. His videos have the details and all the information I need, but they are not drawn out. If you want to know how to make a how-to video, watch his. You don't need an hour to show 5 minutes worth of material.

I just happened across this one today and it ties in with exactly what I have been wanting to do with my monitor wedges. I get quite a variety of EQ depending on which wedges we're using and I wanted a video just like this to try to dial them in. This is also going to come in great because the lead vocalist just switched microphones and it sounds real boxy right now. With the RTA, pink noise, and Bus & graphic EQ, I think I can get this setup just the way I need with our X32.

Thank you very much for all of those x32 videos :-))

Thank you for sharing this as a helpful use of the graphic overlay features of the unit, and the instructions of using the oscillator.

This is a great way for individuals to make progress towards tuning their environments with the features of this unit.

[alexhormann]

LOL, you should check this from different microphone positions. You'll never finish. And when the crowd's present you start again. Happy phase shifting! Hehe
Make your mix fit the room, that's better.

[mikepruett]

drew where do u put the rta in a large room between both speakers?

[OLVRMusic]

I was searching for exactly this :-) thank you!

[airfrais]

I think this is very useful to equalize the speakers as neutral as possible either specially by controlling with different mics and/or oscillators

[lanphanh]

Hi Andrew,
Is the XR18 or MR18 have the pink noise option?
Thanks!

Master EQ is not a panacea to fixing room acoustics.

[englishmanlv]

Also RTA's and 1/3 octave EQs are fine for crude audio work but for really accurate tuning and alignment I tend to use Smart overlaid on a good quality signal processor like a Lake or a Meyer Galileo

[timpadrick]

The first things I would fix are the peaks at about ~130Hz and ~80Hz, as I find such to be extremely irritating :-)

[gicagluca]

very informative, as usual. thank you!

[durulseren]

Its good to show these things but never apply that much eq on your main outs.

[andrewwhite]

It looks in this video like you would want to do the channel EQ and the FX GEQ, but I though it was one or the other. Which is correct?
