How to use Room EQ Wizard Pt. 2 - Acoustic Measurement Analysis

[@revmatchsagas]

This has to be "THE" best video on REW hands down. Can't thank you enough. There are only few people who can explain what they know in an easy to understand manner. 🙏🏼

[@MusicCityAcoustics]

Hi Mohan, thank you so much for your comment. I am so glad you were able to get a lot out of the video! Cheers, -Graham

Part 3... Yes please. Agree with others that this is one of the more useful REW videos available.

[@MusicCityAcoustics]

Thanks so much for watching and for the feedback. I truly appreciate it!

[@jedi774]

@@MusicCityAcoustics glad the feedback is appreciated. Does that mean we can expect a part 3 detailing using the measurements for venues??

[@MusicCityAcoustics]

@@jedi774 We will definitely be making a Part 3. I'm not quite sure when yet, but it will happen eventually.

[@lancelotcreative]

So good. Definitely interested in a part 3 regarding clarity & measurement of venues, houses of worship etc.

[@MusicCityAcoustics]

Thanks, David! I'll add that to the list of topics for a possible Pt. 3!

[@samsoloman4004]

@@MusicCityAcoustics Yes please! I'm mostly into acoustics in concert halls and venues and I would love to see Pt.3 talking about clarity and definition.

[@frago220]

I'd absolutely love to see a part 3 on how to use REW in a live venue setting. That's something that will help my church really tune the speakers to the room.

[@rbdesignsnh]

in that instance, you would probably do less room treament, and more EQ. you would set up your calibrated mic according to the steps in the first video, then if you have a DSP or a physical graphic eq in the signal chain, you would adjust the GEQ to flatten the response that the mic hears within the room while blasting pink noise.

[@danilomingotte5076]

The Part 3 is a MUST ! Please, teach us how to align the phases of a 3 ways sound box. Thanks !

[@MusicCityAcoustics]

Thanks so much, Danilo. We're working on part three, but our focus and expertise are in room acoustics. Unfortunately, driver alignment within a speaker is out of our wheelhouse. REW can certainly be used for it, though.

[@stavroshouiris]

I would personally love to see a part 3 of this series, It's been very informative and educational

[@MixedbyJoshua]

Probably the best video out there on REW! Well done guys!

@@franckrichard9812 Thanks so much!

[@BeatboxChad]

Thank you so much for this! Yeah, I'd love to learn a little more about larger live-music spaces, and would appreciate a video on the measurements relevant to that.

[@MusicCityAcoustics]

Hey Sammy, I will definitely keep that in mind and try to make another video asap.

[@tylercorbin1323]

Live audio engineer here! I'd love a Part 3 to cover those additional topics you mentioned! :)

[@matthegan3415]

I feel like I should have paid to watch this. It’s so good.

[@vdsignature4729]

The way you explain and use REW is very easy to understand. Please continue with another REW part 3 and more. There's still a lot of function in REW that i still can't understand. For example using loop back or accoustic time reference when measuring. Good job and good sharing bro 👍👍👍

[@MusicCityAcoustics]

Thanks so much! We have a few videos in the works but will definitely try to create another REW video soon. Cheers!

[@WhyDoIevenBotherCommenting]

This was great. Coming from a non-audio engineering background, your pt1 & pt2 videos were a supercharge on REW. Would love to see videos on (1) improving clarity for live performances, and (2) using REW to determine studio monitor calibration PEQ settings.

[@Lazarus.09]

Thank you! I've asked others more about the different measurements in REW for my home theater and they always say, don't worry about anything else as only SPL is need for the subs. I was wondering WHERE to put panels and at what frequencies problems were occurring. I learned a lot from your videos, although I need watch again, and then re-watch a few more times after.

[@csdstudio78]

Should be viewing the frequency graphs in log scale. Awesome content, BTW!

[@MusicCityAcoustics]

Yes, that is absolutely correct, and thank you for pointing it out. At some point, while filming this I must have accidentally hit the linear/log view button and didn't realize it. I'll be adding an article to our website about the videos soon and will be sure to clarify the view settings there.

[@GaryMJohnson]

I would love to see part 3 discussing clarity!

[@matthewacker0177]

Amazing video. Gives people a lot of tools. I'm curious why you didn't have a section on using REW to give you recommended EQ settings.

[@adebiyioluwagbenga5596]

Awesome teaching bro. Can't wait for the part three

[@Mixedbyjojo355]

Please cover the part of level matching speakers with each other and sub/s before start measuring ! Also cover the part where how to delay the subs to main for a better phase aligniment! Great video!!!

Thanks for the videos and I was surprised that a company dedicated to acoustic treatment has made video 2. Finally a video explaining how to interpret a measurement. I encourage you to make a 3.4 video, etc. and if possible, take into account how to interpret the Group Delay, ETC and see what happens with the Waterfall at lower frequencies below the Schroeder frequency, we apply equalization. It would be nice to be able to see the decay using equalization. written with translator Greetings

I'm working on a cruise ship and will be headed home to install a ceiling cloud and install a subwoofer. Subwoofer alignment is something I'm trying to figure out ATM. After spending thousands renting studios and literally not touching a single piece of gear and simply using the room itself to make decisions and worked totally in the box I'm determined to get a nice enviroment to work at home.

Great video...excited to dive into the REW software! I am interested in learning more about Clarity. Improving dialogue intelligibility is one of my goals in treating my home theater.

[@kargyr6400]

Thank you very much for the clear explanation! Would have a question though: it seems to me that there is a lack of consistency between the RT60 and the spectrogramm => at a given frequency, larger RT60 = larger decay time right? I seem to have some issues with this, as the frequencies at which RT60 is the larger aren't those with highest decay time in the spectrogram...could you please help me? Anyway GREAT video overall! The case of flutter echo in a treated room is particularly interesting great job

[@garrettboette8069]

[@MeladoCabriocarico]

Congratulations on the content, your videos are very good. I really liked them! I would like to ask two questions: what type of microphone is used in the recording of this rehearsal? What should be the characteristics of the speaker that will serve as the sound source?

[@joshtorrent4220]

By far the best video I could find abt REW. That is amazing work thank you. I was just hoping I could learn how I could actually use this to do eq corrections from my DAW or computer.

[@MusicCityAcoustics]

Hi Josh! Thanks so much! You can use your measurements to determine what should be eq'd to improve your room's response. To start, I'd look at only cutting frequencies and don't eq anything below 500Hz. Keep the eq moves as broad as possible, and don't focus too much on little bumps here or there. The goal is to create a more balanced response, not to get surgical and fix every little thing.

[@ThedjAwesome]

This is a really great video. Thank you.

[@MikkoRantalainen]

22:20 You could also use sub with 180 phase flip active and set cross-over point to 70 or 80 Hz. If your sub has high enough quality, this typically results in higher audio quality overall.

[@WestonWill]

GREAT video on REW, been using it for years but never took the time to dive into all the different results from my measurements. I EQ both home and car audio, I can see some of these features to implement in my upcoming car audio tune. Thanks! More please!

[@oortone]

Great video. REW was a bit frightening at first but now I feel confident using it. One question though, to understand treatment issues better: Whats going on with the big reflection at ~1.5 ms in cloud treated version at 29:50 in the video? That reflection is not in there without the cloud. At 16:15 in the video there’s a similar reflection at ~1.5 ms in both treated and untreated, so that seems to be the same kind of reflection. What might be the source of that reflection? So why did the cloud treatment shown at 29.50 in the video introduce this reflection not present without the cloud.

[@brunorudolph]

Definitely Looking Forward to part 3, 4 or 5 :) Thank you for this Tutorial! Best Breakdown of REW I've seen! I'd Love to see how adjusting Delay can improve the coverage as I'm just on the edge of beginning to understand how phase coherency especially in Low-End Audio can really effect how you perceive things... I bet you could get me the correct complete picture of how Phase adjustment could improve or ruin a coverage plane. Just a beginner here. Are there any books that clearly show how I can make meaningful changes to the PA I work with to improve consistency of Frequency Response and improved Impact? I'll take all the help I can get! So much of the info I find dives so deep so quick I don' know how to make sense of the math of it all.

[@alessiobenedettimusic]

In the video you say to do more measurements: left speaker, right speaker and both. To the left of the REW window, however, I see only two readings: room without acoustic treatment and room with acoustic treatment. Following the measurements when you interpret the data how do you merge the three readings into one reading? Very helpful 🙏🏻

[@MusicCityAcoustics]

For the video, I took and pulled measurements from existing rooms we had worked on and then pulled them into one REW file to make it easier for me to keep track of everything while making the video. You can take several measurements in REW and then average them, but that is not what you see in the video, and it is something I rarely do. Thanks so much for watching! Cheers!

[@MikkoRantalainen]

The biggest low bass improvement for my system was getting DSpeaker anti-mode for it. It can truly make miracles for low frequency problems. Of course, being a DSP solution it can only fix the audio for selected point in room and other locations may get worse, so it's not a replacement for acoustic treatment.
