One of the best tutorials I've listen too on REW. Julian simplifies the terms and gets right to the point without a lot meaningless rambling that exist in so many of these UA-cam videos. His voice is clear with good pace, finally someone who can simplify a complex subject, well done Julian.
Trust me bro I have watched hundreds of video to learn starting the process of measuring the frequency response but every video have something missing no one goes like 12345678910 but good bless you your are the one who tells everything in detail and very short time thank good after like month I got what I was looking for good work keep it up bro
I dont know what Im doing wrong. After applying the correction EQ and testing with sine sweep again I get THE SAME results (just 7dB lower) as if I did not use the eq... end yet I can CLEARLY hear a HUGE difference in the response. Its as if REW sine sweep bypassed Equalizer APO. Edit 1: The generator in REW is indeed not affected by Equalizer APO. Will trobuleshoot it further Edit 2: Google was surprisingly silent about the solution, but Ive managed to dig up some information about how different drivers work with REW. I switched the drivers from ASIO to Java in REW and it solved the problem. My room sounds so much better now. Its amazing. Thank you, Julian! (I didnt go for the Harman curve tho, just pure flatness lol)
Even 3 years later this turorial is perfect. Clear, concise, very easy to follow and extremely difficult to mess up. I don't have a nice measuring mic but I have a cardoid condenser mic with a pretty flat response curve. Made it work with that. Final curve needed a little fiddling with to sound the way I like it but that's just my personal taste.
Appreciate the tutorial! There were a few changes in the newest version of REW to account for since this was recorded, but they were simple enough to figure out. Thank you for guiding from start to finish in only 16 minutes - most other tubers unnecessarily tried to make the same content a 4 part series at 20 minutes per video.
Thanks a lot!! This is very helpful video to get the corrections done with REW and Equalizer APO. House curve having moved to the EQ display after the video was shot was only thing that needed a bit of searching.
I almost never comment on You Tube videos unless it is my son on my account in Minecraft! But I must say what a superb overview, I could not recommend more highly - no fluff just stuff.
Your ability to explain clearly and with an understandable language for not technician is remarkable. Thank you, actually a support from Warren Huart speaks for itself ;-)
Holy crap I went through so many useless REW videos before finding this, this is EXACTLY what I needed. Not some garbage for home theater or studio use etc, but a simple tutorial for optimizing a given 2 channel system in a given room to a target curve and how to actually supply that eq. I already have equalizer apo and I didn't know these files were compatible so this is most excellent. I'm curious to see if rew can ew my system better than I've done it by ear with no measuring equipment all these years (subjectively, of course). My speakers are far from flat response and need a lot of EQ so this will really test rew. And I'm ok with boosting frequencies and requiring more power since I have the headroom.
This is the best video around for calibrating a room using REW and the UMIK microphone, thank you for this, very detailed and easy to follow procedure.
I think you covered the topics very well enough for most users to obtain a good understanding of the key approaches and a decent suggestion of one way to perform the measurements. The presentation quality is also excellent. And you covered a good set of topics that use the easiest tools for room correction. Measurement Microphone - UMIK-1, Measurement software - REW, Your own approach to which microphone positions and orientation to measure, Equalisation Compensation - using EQ filters, and systemwide application of the filters using Equalizer APO. That is a lot of information in one video, that will make it so much easier for those starting out on this journey. Well done.
For anyone with a subwoofer in the system: Set the speaker type to "Full Range" and set the LF cutoff to wherever your subwoofer rolls off. You can usually tell where it rolls off by looking at the response curve, usually around 20 or 30 Hz. I set my LF slope to 24 dB/Octave to more closely match the response curve of my system. After that, you can continue to follow the tutorial as it is. Side note: I brought the target level way down to the lowest trough to get better bass response, and have not run into an issue with the output being too quiet.
I have 5.1 setup. I thought every speaker including subwoofer has to be measured separately (even seven times from various microphone positions) and then an average curve is created for that individual speaker yet the author measures both of his speakers at once (?). Could you please tell me where I'm making a mistake?
@@janlinhart7914 Here's my take on the matter: He's only covering a stereo system in this video, and the difference between the two speakers in his setup is negligible due to them being so close together and close to the listener. You can certainly test and create a custom EQ curve for each speaker in your system; most likely Equalizer APO has the ability to correct each speaker individually. My 5.1 AVR's auto-EQ only corrects for the L, R, and the rear pair of speakers. Correcting each surround speaker individually is probably unnecessary in most cases. I suggest you research how to EQ a surround system, because I don't know exactly how EQing surround speakers work in conjunction with EQing everything else. Also research how to measure and set the proper crossover frequency for your sub, and how to set bass timing using the distance settings in your AV receiver (if you're using one).
Thank you Julian! Your video tutorial on using REW in conjunction with Equalizer APO was exactly what I needed. The straight forward explanation helped me achieve with in short time.
i consider this program as a life hack, GREAT results, and FAST! I've been toying with the Equalizer for years, this beautifully designed program fixed it withing 30 minutes :D
Great tutorial, the only thing I would say is that should only do one speaker at a time. I learned that from Eric Valentine who has some fantastic videos on room acoustics and setting up speakers. He shows comparison of both speakers compared to one at a time, he also suggested to stand in the exact same spot every time you do the measurement as it will also affect the results, and shows this too.
i had to adapt a few things to todays updated REW (REW V5.31), but man if this isn't the easiest sub and like in the world. the absolute perfection of the explanation-structure is just out of this world. you knew what would throw back people and literally included all these steps. for example opening a config into E-APO is not the same as loading into the actual config. absolut brilliant video. and yes, your tut improved my illogical near-field MLP so much to make me write this :)
Thank you very much for mentioning the Harman curve. Before seeing this video I measured my Audio system in my room and I got a similar frequency response, so I was thinking that my room had a lot of bass and low highs, but if I compare it to the House curve you showed then it actually resembles it, and it makes a lot of sense because if I tried to get a perfect flat response at my room then everything would sound very bright with very weak low end. Its very good that you mentioned it because everybody talks about getting a flat frequency response, but none of them are saying that the flat response should be for the speakers themselves, not for the speakers + room
Hahaha, I'm speechless! I'm looking for a tutorial to calibrate my desktop, and I get one shot at a tutorial with someone who has the same speakers as me! It's going to be perfect :) Thank you so much!
What a useful video! Thank you for doing this for all of us out here who wouldn't have been able to figure this out on our own, or at least would have spent a week trying to learn. I is especially helpful that you explained why to use the Harm curve and the optimal points for various settings. Very much appreciated, sir. :-)
I was looking for an alternative to a DSP box (like miniDSP 2x4 etc) since I wanted to run my speakers balanced and keep my signal chain as minimal as possible. Thank you so much for making this video which introduced me to Equalizer APO. You are a lifesaver!
Thank you Julian! I agree with others that your video was fantastic, so clear but best of all for someone like me who's not highly proficient on computers you showed all the steps at a pace I could follow and because of that you've given me the confidence to have a crack at doing it.. Thanks mate..
An excellent tutorial. I had a hard time finding a video that spelled out doing just a basic room correction EQ without going into crazy settings like timing and decay that mixing studios would care about. This video is a bit dated now and could use an update with the current software versions. My PC audio is greatly improved now.
i had to rewind the video multiple times, but i finally got the hang of it. thank you so much for the tutorial. this knowledge is a valuable tool that should really help me get my room acoustics in order 🤓👍 i ended up copying the eq recommendations manually from the export txt file and input those setting into my vst eq... so now i have a preset that i can toggle the eq within the daw
Awesome video, thank you. Running a HTPC with Equalizer APO on it to a DAC to feed my old school 2 channel retro stereo system with old school 80's era floor standers. This video helped me set it up and it sounds great. The straight Harmon curve sounds very "correct". I added a touch of bass as I have a big amp, 12" woofers and like a little room compression at high volumes, to includes ripples in my beer - LOL
So my question to you is this. Was it worth it? I’m about to set up and start but I’m starting to wonder if my expectations are too high. Is the payoff worth all the effort? I guess it doesn’t matter because I’m going to do it anyway :-) so I will answer my own question within a couple days.
@@curtisjohnson944 nah. Not unless you have the perfecty built professional studio space. Just treat your room. Forget those cheap foam things. Just carpet the floor and walls.
Excellent! Excellent! Excellent!!! ... Thank you very much for making this video! ... I've been waiting for somebody to make a clear and concise video explaining a step by step guide for REW... You are clear, organized and to the point. Very easy to follow and to get results... Thank you so very much for not rambling or getting off topic. Just 1, 2, 3... So perfect! - I knew it could be done - And you did it! - Soooo happy right now. I will save this video and watch it tomorrow, pressing pause after every step... Now I can learn REW at my own pace.... So perfect! :)
This is the best video of all out there. (A little explanation of why it's done should have been amazing like for eg: relation between -12db and 75db etc)
You nailed this one. I've watched so many videos about REW and came out with zero understanding or clarity on how to measure properly. This video is fantastic. Thank you!
Thanks for the very informative video. I was struggling to figure out what to do with the umik-1/rew for my car audio setup, and your guide not only made it easier to use, but also explains what is going on (probably one of the most important aspects of equilization).
Wunderbar! I would recommend to try different house curve targets, IMHO the Harmann curve is not ideal and overdone (as the Harmann headphone targest are). Starting point for neutral curve on medium listening levels here is simply 100 0 16000 -4 For typical aged ears 100 0 8000 -3 16000 3 :) Whatever you do, the most important corrections are early in room reflections occuring often in the 150-400 Hz region.
Great way of using rew for eq-ing. But unless your room is acousticly simetrical, i would suggest doing this for each speaker seperatly. And create separate filters for them.
Hi, I've been trying to apply a filter for the left speaker and a filter for the right speaker in equalizer APO but can't figure it out. Do you know where I can find more information on this?
It helped but was still hardy a flat response. I find it quicker just to manually adjust the EQ and in EQ APO. Great video best I've seen explain how to do this.
Fantastic. I used this to measure the best location for my Sonos subwoofer and then EQ things. This was waaaaaaaaay more helpful than the UMIK-1 instructions for REW (which were using an older version of REW too).
Amazing - so much simpler than so may instructions out there! Now all we need is for Julian to get into Roon and show us how to get those measurements into a convolution filter! Perhaps even just manually into the DSP settings - but I'm working on it, maybe this side of Xmas, who knows! 😊
I really agree. Julians explanations is really on spot. Clear and useful. Julian if you only would do the same and show how to get the finished convolution filter in to Roon that would be the best for this audio year.
As an ex-intern at Harman, I suppose the Harman target curve you showed is specifically for Car Audio and not for a mixing environment. Harman supplies audio to Lexus (under Mark Levinson) & Tata (under JBL). Anyways, solid tutorial Julian!! thanks
Excellent explanation Julian. Thank you very much. Of course, previous knowledge about REW and Equalizer APO is necesary in order to be able to follow your instructions. In that case, your description is crystal clear. Congratulations!!!
Thank you very much for your excellent and helpful video! I managed to calibrate my system and I am super impressed with the increased clarity, balance and fine details in bass, mids and highs! Good work!
Hi Julian. Thanks for the excellent tutorial. I am about to use the UMIK-1 and EQ APO to correct my room acoustics, but there is one thing I don't understand. You are using 2 speakers to make the correction filters for Eq APO. My question is: does APO apply the same identical correction filter to both Left and Right, or does the REW software produce two separate equalization settings for Left ant Right individually? This would seem impossible if the UMIK-1 is pointing at the centre of the audio image, but maybe some software magic happens inside REW.
Good guide overall, but there were some issues I saw that can be improved upon. First, measurements of the speakers should be done individually, so separate L and R speaker measurements. Measurements are most sensitive at higher frequencies and playing both speakers at the same time creates comb filtering which screws up the frequency response. Adding to that it is preferred to use a 90 degree mic orientation (mic pointed at the ceiling) when doing measurements in the room as opposed to the 0 degree measurement used in the video. Lastly, you did well with regards to the target curve not being flat, but setting the flatness target at 1dB in my experience results in poor sound as REW uses way too many filters to achieve the target. Every IIR filter being used creates time domain distortion. Best results are achieved using the fewest amount of filters possible. And using filters with lower Q values. Instead try a flatness target of 2 or even 3dB. At 1dB REW may use 15-20 filters whereas at 3dB it may only use 5 filters, which will end up sounding better. For best results, buy a MiniDSP DDRC-24 and start using DIRAC!
Not to dogpile here, you also mis-spoke a bit on the GRAPH->VAR (variable) SMOOTH function, which is only a display option that gets rid of the multitude of tiny frequency dips and mellows them out so you can better visualize the general (smoothed) frequency response. It also doesn't have anything to do with how humans hear, it's strictly for display.
"it is preferred to use a 90 degree mic orientation (mic pointed at the ceiling) when doing measurements in the room as opposed to the 0 degree" This isn't true. 90 deg calibration is only supposed to be used for surround sound systems. You should point the mic at the speakers and use standard calibration for any stereo system.
For more accuracy, measure the left and right sides independently with REW and create a stereo config for Equalizer APO... you can also export L/R impulse response files, combine them into a stereo impulse using an audio editor, and use convolution instead of using multiple EQ bands.
13:18 - Just a quick question - I'm assuming you meant to show the *filter* correction file at that point in the vid, instead of the *mic* correction file?
i did this in a slight different way(a few months ago actually and actually totally different): mic in hand pink noise full range at your typical listening volume moving the mic in sphere pattern in my listening area start recording the average with the rta tab did about 70 averages. then looked at the response and corrected by hand on a 31 band geq inserted on my system audio via audio hijack. repeated until the curve was almost flat in the averages. i must say i'm very pleased with what i got and i've been mixing records much faster and better then before, even mastering engineers did almost nothing EQ wise. i admit haven't compared yet with a sine sweep but will do in the next few days
One of the best tutorials I've listen too on REW. Julian simplifies the terms and gets right to the point without a lot meaningless rambling that exist in so many of these UA-cam videos. His voice is clear with good pace, finally someone who can simplify a complex subject, well done Julian.
I've watched several REW videos on UA-cam; this one is the most comprehensive and is easiest to understand. Thank you :)
this.
Cannot agree more. Was going nuts watching several videos and making sense of nothing.
expect nothing less from 'ze chermuns' :)
agreed. by the far the best beginners tutorial. thanks!
L and R channels should be measured separately.
This is huge problem of the video! Otherwise the tutorial is good.
I bookmark this and rewatch it whenever I EQ. REW has changed a good bit in the last 3 years. I hope you will update it showing the new menu choices.
Trust me bro I have watched hundreds of video to learn starting the process of measuring the frequency response but every video have something missing no one goes like 12345678910 but good bless you your are the one who tells everything in detail and very short time thank good after like month I got what I was looking for good work keep it up bro

Edit 1:
The generator in REW is indeed not affected by Equalizer APO. Will trobuleshoot it further
Edit 2:
Google was surprisingly silent about the solution, but Ive managed to dig up some information about how different drivers work with REW. I switched the drivers from ASIO to Java in REW and it solved the problem. My room sounds so much better now. Its amazing. Thank you, Julian! (I didnt go for the Harman curve tho, just pure flatness lol)
I use "JAVA" but still mesure the same as before...
Even 3 years later this turorial is perfect. Clear, concise, very easy to follow and extremely difficult to mess up.

@@CorneliusHolden press EQ button, in popped up window go to Target settings

Best REW ‘how to’ ever! Thank you! 😀👍
Thank you very much for your excellent and helpful video! I managed to calibrate my system and I am super impressed with the increased clarity, balance and fine details in bass, mids and highs! Good work!
This is so helpful! Really appreciate this video and I am excited to mess around with REW.
Finally a good tutorial on rew, thank you, sir!
What a perfect lesson! I am so happy and grateful! Thanks a lot!
Best Tutorial ive seen on UA-cam!!! Thank you!!
Hi Julian. Thanks for the excellent tutorial. I am about to use the UMIK-1 and EQ APO to correct my room acoustics, but there is one thing I don't understand. You are using 2 speakers to make the correction filters for Eq APO. My question is: does APO apply the same identical correction filter to both Left and Right, or does the REW software produce two separate equalization settings for Left ant Right individually? This would seem impossible if the UMIK-1 is pointing at the centre of the audio image, but maybe some software magic happens inside REW.
this is so so so useful, thanks man! This helps a lot when building and designing bluetooth speakers!
Great video. Just got my umik-1 and very excited to put this knowledge to use. Thank you!!
It was a pleasure listening to you. Thank you sir.
Hi Julian, thanks a lot for this nifty little guide. Helped me out quiet a lot. Thanks mate.
Good guide overall, but there were some issues I saw that can be improved upon. First, measurements of the speakers should be done individually, so separate L and R speaker measurements. Measurements are most sensitive at higher frequencies and playing both speakers at the same time creates comb filtering which screws up the frequency response. Adding to that it is preferred to use a 90 degree mic orientation (mic pointed at the ceiling) when doing measurements in the room as opposed to the 0 degree measurement used in the video. Lastly, you did well with regards to the target curve not being flat, but setting the flatness target at 1dB in my experience results in poor sound as REW uses way too many filters to achieve the target. Every IIR filter being used creates time domain distortion. Best results are achieved using the fewest amount of filters possible. And using filters with lower Q values. Instead try a flatness target of 2 or even 3dB. At 1dB REW may use 15-20 filters whereas at 3dB it may only use 5 filters, which will end up sounding better.
For best results, buy a MiniDSP DDRC-24 and start using DIRAC!
Not to dogpile here, you also mis-spoke a bit on the GRAPH->VAR (variable) SMOOTH function, which is only a display option that gets rid of the multitude of tiny frequency dips and mellows them out so you can better visualize the general (smoothed) frequency response. It also doesn't have anything to do with how humans hear, it's strictly for display.
"it is preferred to use a 90 degree mic orientation (mic pointed at the ceiling) when doing measurements in the room as opposed to the 0 degree"
This isn't true. 90 deg calibration is only supposed to be used for surround sound systems. You should point the mic at the speakers and use standard calibration for any stereo system.
Thank you for sharing the knowledge!
great !! very informative - I've been using REW but with many mistakes - PLEASE make a video using REW and a MiniDSP unit
Excellent explanation of REW & Umik-1 setup process. Thank you for posting.
Best REW tutorial I have seen so far. If possible, might be make an updated video to show how REW work with Roon. Again, Thanks for the great video!
This is GOLD. Thanks Julian Krause!
For more accuracy, measure the left and right sides independently with REW and create a stereo config for Equalizer APO... you can also export L/R impulse response files, combine them into a stereo impulse using an audio editor, and use convolution instead of using multiple EQ bands.
Extremely well done job. My compliments
Thank you! You made a complex procedure really easy with your excellent step-by-step instructions. Fantastic work.
Hi, very informative and the explanation is very straightforward. 🎉
Excellent. Concise and easy to understand.
13:18 - Just a quick question - I'm assuming you meant to show the *filter* correction file at that point in the vid, instead of the *mic* correction file?
Thanks for the guide, btw. I didn't even know EQ APO was a thing until you mentioned it. ;)
This video is GOLD.
You are a legend Julian 🙏 love from India♥️
Thank you Julian. All set.
Excellent tutorial in every way! Thank you so much!
☝️What I miss in this REW software is a hearing test of your own ears.
Btw - the explanation in this video is excellent 👍
Thank you for the hard work man. That helps a lot of people, including me.
First try like you said, than do a little different, but thanks for explaining the basics!
Awesome video. Very well explained, comprehensive & easy to follow. Many thanks!
i did this in a slight different way(a few months ago actually and actually totally different):
mic in hand
pink noise full range at your typical listening volume
moving the mic in sphere pattern in my listening area
start recording the average with the rta tab
did about 70 averages.
then looked at the response and corrected by hand on a 31 band geq inserted on my system audio via audio hijack.
repeated until the curve was almost flat in the averages.
i must say i'm very pleased with what i got and i've been mixing records much faster and better then before, even mastering engineers did almost nothing EQ wise.
i admit haven't compared yet with a sine sweep but will do in the next few days
just out of curiosity i tried your method, the results are almost identical. and i'm very satisfied of how my room sounds :D

Hello.
Thank you for the detailed tutorial.
Is the procedure the same for Mac users as for Windows?
