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 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.
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.
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.
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.
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.
Thank you for the video! This is awesome. Requesting part 3 with eq correction on mac... There is no Equalizer APO on mac and I don't know which software to use to get the correction after the measurement.
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.
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.
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
Hi sir, Im building Acaustic panels for mixing room (DIY), I'm not an expert like you, I need your help, what Density do i need for Acaustic panels to absorb bass frequencues, I'm thinking about rockwool safe n silent pro 370, The density is 80kg/M3, I don't know this will work or not, please give me your direction. Thanks, Rajkamal jangir India
Hey! Thanks so much. We have a few other videos in the pipeline right now but I will definitely keep that in mind and try to make a part 3 video as soon as possible.
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.
Thanks for the video. Once i get this done, using my ONKYO AVR (which does not have dirac), how can i adjust the built in 10 band equalizer using the info i get from REW? Thank you :)
Hi, Room EQ Wizard is very most helpful to entry level audio testing analyzers but this test results may not be accurate For example you test the frequency response for one channel in one listening position Again you test after minute your test totally changes it can't give stable Equlization when applying EQ Filters in your frequency response curve. Try to learn FFT based Audio test measurement which it will helpful in real time
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.
Mac-Win-What? Linux is used in MOST industrial applications, it runs the internet, routers and devices. Linux also runs MOST non home computer environments . . . REW is awawsome. I send John a few bucks every time there's an upgrade. He DESERVES it, please do the same..
Really good! I understand a lot with your video. About smoothing: which is the best smoothing for Room EQ Curve calculations. Is there any option you do a video about Room EQ Curve Calculator?
I felt that your voice audio suffered from a lower frequency resonance (probably in the 200Hz ranger). Has your room be treated for a good RT60 response?
1:11 Should speaker placement require an equilateral triangle, or can any angle work as long as the microphone is equidistant from the drivers? Additionally, could you please define "ear height" if possible? Many recommendations, such as Rec. ITU-R BS.1116-3, suggest that placing the geometrical midpoint between the tweeter and woofer at ear height is ideal, and that speakers should be calibrated to 85 dB SPL using pink noise. Could you also provide insights into how to distinguish between room-induced and loudspeaker-induced irregularities for accurate measurements? I've noticed that often this approach leads to a match between the room and loudspeaker characteristics rather than achieving neutral acoustic treatment. Changes in the speaker or orientation seem to negate any treatment, even after matching/calibration of SPL, as differences in amplifier power and driver performance at the same loudness can result in significant variations in frequency response.
Hey all! I am currently treating my room and using REW for measurements. I have achieve a super nice low end response using treatment, however I have a MASSIVE (about 30db compared to the average of the rest of the response) dip between 6k and 12k. I can find all sorts of information on low end issues and common fixes for that but I cannot seem to find anywhere where they address high end nulls. Could anyone point me in the direction of a good resource or give me some common tips/things to try to fix this? Thanks in advance!
Hey, would i be able to send you before and after treatment measurements and you let me know if what i did was effective and what i could improve on given my room’s limitations?
Good video. (One bit of constructive criticism if I may: you'll get a more pleasing sound out of that SM7 if you let it hear the resonance from your nose and sinus cavities. The sound is rather 'nasal' which, of course, is actually the lack of nasal presence.
I would love to see video about group delay. If I've understood correctly, problems in group delay are the most common cause for poor or sloppy bass even in home studio.
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
Hi thanks for the great video! I have question regarding that last comparison of different speaker positions: In a real world application, would this mean you don't put any panels behind the speakers, because the most balacend response came from that positioning right up to the wall?

I have no way of changing the room configuration, in terms of speaker placement or sound insulation. What i want is to try to flatten the peaks of frequancy response. Would i be abvle to do that with a 31 band equalizer and try to smooth the frequency responde, and have a flatter FR, or that doesnt make sense? What would i need to have in mind? Thank you!
Hi There :) .. could somebody help me please? how to put the graphic of 2 measurements together on he same screen to compare the EQ curve? I dont find this option in REW
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.
That`s a highly competent and interesting video. I know I`ll have to study it a second time and I am sure I can take a lot of advantages out of it for modifying my own studio. Thank`s a lot. (/from Germany) 🙂
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 👍👍👍
Thank you for such a informative video. Everything was explained in great detail and for people like myself who found REW overwhelming this gives a good insight into this amazing tool. Again, thanks for taking the time to put this together. Much appreciated
Nice video! Quick question: when the SPL graph says 100 db at 1000hz does it count also the energy from the reflections? If so, can I somehow see what is the energy from the sound coming first at the microphone (i.e. no reflected sound)? many thanks!
Hi Evan, great question. Yes, the SPL graph is showing a combination of direct and reflected sound. You can see energy overtime on the impulse response and filter impulse response windows. They don't show the frequency response, but it is a great way to see the relationship of direct to reflected sound and to better understand where the strongest reflections in your room are coming from. I believe you can "window" your measurements to only show the first few milliseconds of information captured. This would eliminate most of the reflected sound. Viewing measurements this way is more common when designing speakers or gear but not often used when measuring a room's acoustic properties.
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 🙏🏻
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!
Hi Kamil, you can find your speaker and listening positions before treating a space. We have found that the room's most balanced listening position rarely changes before and after treatment. Sometimes the speaker placement will move a bit as the room is treated. Mainly because, with treatment, you can widen your speakers a bit more and have them further away while retaining clarity and focus. In our video series with Acoustics Insider, we dive pretty deep into this in part one. Check it out here. th-cam.com/video/kTOD5DUW9Ak/w-d-xo.html
Yes, it can. Typically, speakers are measured individually for both stereo and 5.1 setups. REW does also offer a multi-capture upgrade to the software.
Thank you for making these videos. I'm about to make curves for a pair of vintage PA cabs that I've restored so I can push around EQ sliders in hopes of flattening out the very peaky response.
Fantastic video! I purchased a mic and installed REW 11 years ago. The manual then was very cryptic. Your videos are packed with detailed and intelligible info on installation and basic use. Thank You! I cant wait to start with some measurements. Also, I vote for a part 3.
I just discovered REW and this video series was linked on the home page. WOW! Wish all software I use had such an amazing tutorial series. Yes, please do a Part 3. Also, I'd love it if there was a "Part 0" in which you go over basic acoustics... at least for what's useful for room acoustics. Anyway, thank you!
Hey! I am so glad you found the video helpful. We don't have a part 0 but we did just do a four part video series (half on our channel and half on the acoustics insider channel) where we go through the entire process of designing, treating, and testing a studio. Check it out!
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.
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.
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.
Hey Guys, the two videos you have are great to get into REW, Im using it to tune a theater with 1080 seats and flown line arrays. Any tips or tricks for tailoring the settings in REW for use in this application?
These two videos have been outstanding. Thank you so much for putting in what I'm sure was a ton of work to format this so eloquently! I've actually been putting this video off cuz I was worried REW was going to be too complex (given all the options it provides), but after finally watching this I don't feel so intimidated anymore :)
Please could you put subtitles to be able to see your video in my Spanish language, or even less so could you do part one and part two in Spanish, I would really appreciate it
Wow such a great video! I watched it taking my time and taking a lot of precious notes. Indeed I fought for years against a null at around 40Hz which must be absolutely impossible to tame, regardless the big investment in adsorption!
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. 🙏🏼
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,

Part 3... Yes please. Agree with others that this is one of the more useful REW videos available.
Thanks so much for watching and for the feedback. I truly appreciate it!
@@MusicCityAcoustics glad the feedback is appreciated. Does that mean we can expect a part 3 detailing using the measurements for venues??
@@jedi774 We will definitely be making a Part 3. I'm not quite sure when yet, but it will happen eventually.
@@MusicCityAcoustics Looking forward to it. Great video. I'd love to see you shoot a small PA rig, as well.
@@MusicCityAcoustics Looking fwd to Part 3 for a church PA system application
So good. Definitely interested in a part 3 regarding clarity & measurement of venues, houses of worship etc.
Thanks, David! I'll add that to the list of topics for a possible Pt. 3!
@@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.
Probably the best video out there on REW! Well done guys!
Hi Joshua, thank you so much for watching and the comment. I really appreciate it!
Agree
@@franckrichard9812 Thanks so much!
I would personally love to see a part 3 of this series, It's been very informative and educational
my biggest takeaway was to befriend someone who is passionate about room acoustics and knows how to use REW...
The Part 3 is a MUST ! Please, teach us how to align the phases of a 3 ways sound box. Thanks !
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.

Hey Sammy, I will definitely keep that in mind and try to make another video asap.
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.
Thank you for the video! This is awesome. Requesting part 3 with eq correction on mac... There is no Equalizer APO on mac and I don't know which software to use to get the correction after the measurement.
Should be viewing the frequency graphs in log scale. Awesome content, BTW!
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.
I feel like I should have paid to watch this. It’s so good.
Is the spectrogram reflecting the T20 selection you made in the RT60 view?
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.

You use a software called "Room EQ Wizard", so I was waiting for the "Room EQ" to be worked out&applied, but that was never touched on.
May I ask why?
Great job. Really appreciate ur knowledge and understanding sound, acoustics, REW... how to contact u... we have a project to discuss
Hi ! Awsome contents ! It would be great to have a part 3 with a procedure to optimize P.A.s ! Cheers !
My impulse & rt60 & everything looks different from your's.
Great tutorial. Thanks. I would be interested in learning more about the clarity adn lowest phase analysis. Are you able to do a viseo on this?
Hey! Thanks so much. We have a few other videos in the pipeline right now but I will definitely keep that in mind and try to make a part 3 video as soon as possible.
I would have liked to see the "Clarity" measurement feature because I'm trying to improve our church speaker positioning issue.
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.
Thanks for the video. Once i get this done, using my ONKYO AVR (which does not have dirac), how can i adjust the built in 10 band equalizer using the info i get from REW? Thank you :)
Hi,
Room EQ Wizard is very most helpful to entry level audio testing analyzers but this test results may not be accurate
For example you test the frequency response for one channel in one listening position
Again you test after minute your test totally changes it can't give stable Equlization when applying EQ Filters in your frequency response curve.
Try to learn FFT based Audio test measurement which it will helpful in real time
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.
when there is the opportunity, please something about clarity and other acoustic parameters. BLESSINGS.

For all the full-range measurements shown, was that using the L+R+Sub playback configuration?
so you can EQ with "APO" ?
As they mention : "is best used in conjunction with Room EQ Wizard"
Thought i would see that point aswell in your video :o
Hey all! I am currently treating my room and using REW for measurements. I have achieve a super nice low end response using treatment, however I have a MASSIVE (about 30db compared to the average of the rest of the response) dip between 6k and 12k. I can find all sorts of information on low end issues and common fixes for that but I cannot seem to find anywhere where they address high end nulls. Could anyone point me in the direction of a good resource or give me some common tips/things to try to fix this? Thanks in advance!

Hi thanks for the great video! I have question regarding that last comparison of different speaker positions: In a real world application, would this mean you don't put any panels behind the speakers, because the most balacend response came from that positioning right up to the wall?
What do you think about using the Moving Mic Measurement technique? I noticed that the Noise button was greyed out in your settings. How would I use pink noise and MMM?
I have a question:

thank you! For the speaker placement tests, were those done with a single speaker?
So if you record in at 80 SPL is that your reference point to observe a +db or -db from 80 SPL on the graph?
I would personally love to see a part 3 of this series, It's been very informative and educational
Would like see a video on group delay and minimum phase as not all of us can afford to buy smaart software to do church systems
Great video. Thanks! It would be great to have part3!

Sometimes the speaker placement will move a bit as the room is treated. Mainly because, with treatment, you can widen your speakers a bit more and have them further away while retaining clarity and focus. In our video series with Acoustics Insider, we dive pretty deep into this in part one. Check it out here. th-cam.com/video/kTOD5DUW9Ak/w-d-xo.html
Yes I need for churches and venues,
What would a 1.35ms 0-100% ETC mean for my main speakers? Is this the acoustic audible beep before measurements? Thanks
Can this software be used to analyze a 5.1 surround setup for film post production? Or is it just for stereo with a sub?
Yes, it can. Typically, speakers are measured individually for both stereo and 5.1 setups. REW does also offer a multi-capture upgrade to the software.
My head hurts...too many questions....I'll keep absorbing, great video 👍🏻
Thank you for making these videos. I'm about to make curves for a pair of vintage PA cabs that I've restored so I can push around EQ sliders in hopes of flattening out the very peaky response.

Can you show how to (in pt.3):
1. Measure a PA system outdoors?
2. Measure delay between Subs and Tops?
I just discovered REW and this video series was linked on the home page. WOW! Wish all software I use had such an amazing tutorial series. Yes, please do a Part 3. Also, I'd love it if there was a "Part 0" in which you go over basic acoustics... at least for what's useful for room acoustics. Anyway, thank you!
Hey! I am so glad you found the video helpful. We don't have a part 0 but we did just do a four part video series (half on our channel and half on the acoustics insider channel) where we go through the entire process of designing, treating, and testing a studio. Check it out!
@@MusicCityAcoustics THANK YOU! Amazing stuff.
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.
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.
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.
This video explained a lot of my questions!! Thank you for sharing this incredible knowledge!
Hey Guys, the two videos you have are great to get into REW, Im using it to tune a theater with 1080 seats and flown line arrays. Any tips or tricks for tailoring the settings in REW for use in this application?
These two videos have been outstanding. Thank you so much for putting in what I'm sure was a ton of work to format this so eloquently! I've actually been putting this video off cuz I was worried REW was going to be too complex (given all the options it provides), but after finally watching this I don't feel so intimidated anymore :)
Please could you put subtitles to be able to see your video in my Spanish language, or even less so could you do part one and part two in Spanish, I would really appreciate it
Wow such a great video! I watched it taking my time and taking a lot of precious notes.
Indeed I fought for years against a null at around 40Hz which must be absolutely impossible to tame, regardless the big investment in adsorption!
I have the same effect just moving my speakers around the room. Just had to apply basic acoutic rules and its works for me)
Part 3 please!!
Great videos. You def wake up earlier than me sir! Any chance you are going to make that part 3?
