[@VeniVizzleVici]

Thanks. You've helped a stranger. You are appreciated.

[@tiagovirago]

So Rew helps with 1. Speaker placement 2. Acoustic treatments for flattening the curve 3. Purchasing subs when the dip is too great. 4. Change the crossover point on receiver. 5.Help with flattening with calibration if you have a 1/3 octave eq or better. (Which I don’t). What it’s not is: a auto flattening system that creates a curve for your receiver, like audessy? And I know it also has its problems. I just am looking for this to autocorrect what I cannot change... will it do that?

[@Audioholics]

Thank you so much for doing this!

@@tiagovirago REW has the ability to auto generate EQ filters based on a 'ideal response' the user sets (the room curve). those filters can be imported in all kinds of hardware or software* EQs. (or set manually on a graphic EQ device) for a receiver alone application, the receiver would need to actually offer the option to manually apply EQ settings. *Equalizer APO is a free software that can do channel routing and other comprehensive settings, EQ incuded...

[@jeremiahchamberlin4499]

Thanks for leaving this up for four years. Just ordered the Dayton Audio package for testing both components and room acoustics from Parts Express. I have acquired enough gear, now I need to treat the room in order to optimize my speakers, and finally figure out how to integrate the four different subs I’ve acquired.

This is not a video for beginners. REW is something which needs to be explained slowly and will require a ton of videos showing settings and why you are choosing a particular setting.

[@rlwings]

Agreed! This video assumes a lot of prior knowledge of concepts and terminology... Would love to see a step-by-step video explaining in detail exactly what's going on, which settings to choose, and why.

[@PoesAcoustics]

NewYorkBlack most of the settings one needs, If using the approach I showed, are preset and will work fine. I did show settings and explaining why would have made this far more technical that was appropriate.

[@PoesAcoustics]

Randy Levine sorry guys. I hear your complaints loud and clear. Sounds like you guys want a video that goes into the software mechanics more than anything. I’ll talk to Gene about doing that. A lot of settings are best left alone but I can at least go through them and say that.

[@reid1boys]

Agreed... a true beginner, like myself, has basic knowledge. If you really want to help a beginnner, start at step one of how to set up rew, STEP BY STEP. If you mention something, anything, explain it to us. You glosss over settings like we know what they mean.... we do not know, tahts why we are here. I appreciate all the time and energy making videos, but we really need a day 1 start, and gradually moving up. Where is the day 1 video for dummies? lol

One of the greatest mysteries known to mankind is why people still think a music track is of any benefit to an instructional video at all, let alone a completely inapropriate 'happy' song that stays at one, too loud level all the way through. When KZbin began it could just about be forgiven but with so many similar comments over thousands of videos, you would have expected most people to have learnt that music serves NO purpouse other than to ruin videos.

i watched the entire video and come away with: now what? how do i USE the measurements? i kept hearing "EQ", i could "EQ" the room. how?

[@josephfranzen5626]

You need a way to implement the PEQ filters you can generate if you go to the EQ tab. Such as MiniDSP, Dirac Live or Audyssey EQ-X.

[@hitekhead]

hi Matthew, thanks for the video. It seems so many have forgotten the purpose of warble tone generators rather that a steady sine wave sweep. Some of the effects in your video may not be real if a warble tone sweep was done. I am sure you are familiar with them (warble tones) and their purpose. Even pink noise has its down side. Any ideas why we can not select warble 1/2, 1/3 octave, etc? thanks to Room Equalizer Wizard also!!! looking forward to your reply. Cheers

First, Thank you for making this. I love watching your and Audioholics videos. One thing that I see missing from everyone that have done a video similar to this, is plugging in the actual correction into the AVR.

[@AH-wr1ir]

You shouldn’t start a sentence with “first” and then omit to use “second” or “third” etc later on. :)

[@Elitoh7]

@@AH-wr1ir You are absolutely right! I should have said "Firstly". But thank you for replying on my grammar mistake and not the actual subject at hand. A year later at that. I'm sure someone looking for help with audio correction will find your grammar correction more valuable! Again, thank you.

[@AH-wr1ir]

Elitoh7 😂 I enjoyed your reply, however, please note that, if you start with “Firstly”, then you should also have, as a minimum, “secondly” as well. Is there a time limit for good grammar? 😄

[@Elitoh7]

@@AH-wr1ir It always amazes me how Cambridge scholars such as yourself have the time to correct all of us grammatically incorrect youtubers. What is even more comical, you still didn't have anything to add about the topic at hand. If you don't already have one, you should think about starting a channel about grammar. Finally, I don't think you are correct on use of "First" in the beginning of the sentence. It's not a requirement or minimum to say "second" when you begin a sentence with first. You can argue that till you are blue in the face and I still wouldn't care. Now please, if you have something of value to add to this topic of audio correction, please do share this information.

[@AH-wr1ir]

Elitoh7 i am sorry if i have offended. I thought we were having a light hearted exchange. 😄 as it happens i use REW and enjoy messing about with different convolution filters in Roon. my best results have come from avoiding any EQ above 3000hz. any recommendations?

[@reid1boys]

Ok, Ill try to give a couple. IN settings, you dont really explain certain things. For example, why are you doing L/R and sub sweeps only? In a 7.1 system, are we only doing 2.1 channel sweeps? You have it set at -22db, why is it at that setting? Should we always use that setting? Why do you choose 1/6 smooting vs other options? You obviously chose 1/6 for a reason.... why? I could continue on, but I think you get the point. This is not meant to be a criticism, but more of an admission to my lack of understanding on how to use REW. I want to be able to use and understand it, not just follow a few steps I watched someone do on a video. I greatly appreciate the time you and others have taken to try and help many of use newbies.

The background music wasn’t that far in the background and it was quite loud and distracting. Also when you are talking about what parameters you are using or are going to use we, the viewer can’t see immediately where your cursor is at on the screen because it’s a small arrow on a white screen with dozens of black lines/boxes and type. It would be helpful if you said where the cursor is like “if you look at the top left side in this box that is titled …”. That way we can see what you are going to click on before you do it and move the cursor again.

Came to this video through Audioholic’s Room Treatment Series of podcasts. Inspired me to purchase the UMIK-1 and download load the REW software. Wow! It is not easy to get started with this stuff. You breezed right through, “And I connect my laptop to my Onkyo receiver and choose it as my output device from the drop-down menu.” = = Two hours later after determining that MY Onkyo receiver wasn’t recognized by Windows 10; I had downloaded files for my Oppo BDP-105D over the internet and chosen the correct input for it.

@@PoesAcoustics yes, how to proper measure a speaker with calibrated mics and software (frequency response without anechoic chamber) to check if the manufacturer claims are real or just marketing and for the diy people that buy already made speakers But also try to make their own designs just because it's fun and rewarding

[@PoesAcoustics]

i raul I have something planned that should address this. Now that the weather is nice we will start measuring speakers again and I plan to video the process and create a video of what we are doing. Just a heads up, what we do is a very by the books approach and as such, hard to replicate without spending some time building your own measurement rig. James Larson takes his work very seriously and built large custom rigs to measure speakers without much diffraction or reflections from the rig. Still, it will show how we do it and what it takes to get good measurements. This won’t be done for a few months however.

Do you have to eliminate the cross over on your avr in order to get a full sweep ? My crossover is at 80 hz so would I be missing the frequencies less than 80 when performing a sweep (speakers set to small).

This software n similar is just great, and yet you still need to make the correct decisions, from relevant listening positions, plus at critical crossover. and simply strive for smoothest overall similar response from ea loudspeaker to seating consideration is goal. One doesn't NEED to use any specific software or measurement tool to achieve this,.a RadioShack sound level meter n test tone disc even works fine! That n lots of positioning trial n error n listening, measuring, listening, measuring, moving, yards yada.

"You can use a mix of sealed and ported". Oh, thank god, because I have sealed and open panel! :-) /S On a more serious note, is it worth throwing out the severe outliers like the one you show far below the other curves with the flatter inflection points? This obviously assumes that those were generated with the sub/listening placement outside the norms, rather than at the primary listening position. I found the comment you made about multiple subs very interesting. Does it seem to be enhanced (improved) running L+R over separated stereo, or vise versa? Assuming...assuming...asssuming... Yeah, damned non ideal equations. I was in an empty living room once with plaster walls, and I can tell you for a fact that they are MUCH more reflective than drywall. You could clap (an impulse) and hear about 10 or more reflections damping down VERY slowly compared to an empty drywall enclosed room. I suspect this comes not only from the stiffness of the plaster surface directly but also the increased stiffening of the entire comparative wall due to the skins stiffening the overall stud/plaster wall. Also, why would you EVER want a room that is a perfect cube, sounds like the perfect storm for 3D temporally extended room axes excitation? I'm saying this just on personal impression, not actual measurements. Also I expect large panel speakers like mine (Maggies) do not excite the vertical axis nearly as much as a point source, just know a bit of physics (dangerous, I realize). Good vid, thanks. "How it works and how livable it is" Uncommitted half-heartedness, I say! :-/ :-) (kiddingly) Measured delay on the subs also seems reasonable considering the mass involved in a sub driver, especially a sub like my Velodyne (4 hz resonant IIRC), even considering the massively powerful 'motor' compared to say an electrostatic, or even a much smaller much higher resonance more standard cone driver. Also keep in mind that there are MANY more kinds of distortion than just THD, and that IIRC, odd harmonic distortions are much worse than the evens, from a pyschoacoustic standpoint. Could be full of **** on all of this, but it is my subjective experience, ear wise. "The sound that you hear in the room is more the room than the speaker itself". Uh huh, that must be why my sub sounds SO much better than pretty much all the others I've heard, at least at that price point (I certainly haven't heard them all, BTW). I get what you are saying, though. And yes, placement is CRITICAL. On a more humorous note, I had a 'golden eared' technician from one of the retailers come out to set up a brand new delivered set of speakers (a standard service of this particular retailer on more expensive speakers) and when he was done and satisfied I informed him that the tweeter was not operating on one side. And I don't remotely claim to be 'golden eared'. Audioholics is a superb business name, BTW. :-) Also let me qualify all the above by saying my knowledge in this area is minuscule compared to yours, so I'm not seriously challenging anything you say. Cheers. PS, for anyone actually having read this far, the GIK vid is another one I've seen that seems to be useful, although it is a bit more of a commercial.

[@livingstones1196]

Just play pink noise through your PA system, or whatever speakers you are using...hopefully they're halfway decent. Record the response then make the necessary adjustments using your graphic EQ to make the room as flat as possible. Now you have essentially taken the 'room' out of the equation and can begin mixing your band. :)

[@johnpoo1662]

People say avoid using the Audyssey mic for measurements bla bla bla. But it is a full range mic so can cover the entire freq range Audyssey corrects for (5-20k?), so no problems there. Does the lack of calibration file really matter if youre using the same mic for all positions, and purely to manually set the sub crossover point? (which Audyssey/AVR often screws up).

[@number1pappy]

Sigh....I just want to know how the changes you make with "rew" are implemented into your avr? I have a denon avr. When you make changes to the frequency curves with "rew" connected to your avr thru a hdmi cable does it automatically change the Eq settings in the internal EQ of your avr?....please anyone????? I'm litterly at the point of begging at this point!...lol!!

[@Audioholics]

What? REW is measuring the acoustical response in your room of the changes you are making to your system. When you alter the EQ, delay, level, phase, etc through your receiver and on your subs, you measure those changes with REW. The ONLY way REW can EVER make changes to your system is if you're using a room correction system like DIRAC or mDSP but that goes beyond the scope of this video. REW is being used as a measurement device here, NOT as a device to implement corrections to your system.

[@number1pappy]

@@Audioholics well thank you so much for clearing this up! But,as a "nubie" you kinda get the impression by watching yours and several other videos on "rew" that it corrects speaker issues. The videos are excellent in the sense they show how to read frequency graphs an so on. But not one video has shown the viewer how to use the info given by "rew" to change settings on an amp or avr or even how to change settings to correct particular issues one might have in a given room. It's awesome to be able to see how a speaker is performing but just knowing a speakers performance curve without being able to correct anything in my opinion is kinda worthless.thank you again for clarifying this issue! I now understand I need to purchase a "dsp" to be able to correct the the frequency response my speakers have in my room. I will say it would be nice to see a video on how to properly change the settings in an avr to change or "correct" any issues in a given room. Its something that is lacking in any video I have seen myself on KZbin and I'm sure by reading several other comments that I'm not the only one who is a little confused on what to do with the info "rew" gives you tou implement correction to a room.

[@missileGauges]

So what do you do if your amplifier don't have an HDMI? (Nad 368)

[@operamatthew]

ordered mic today. can’t wait to get started

[@hillpuller]

Thanks for the great info! I have just setup my first home theater and after watching this I feel I can attempt to calibrate it myself. Great job!

[@randalllawkin]

Are those philharmonic speakers!!🔥👍 nice

[@PoesAcoustics]

Randall Lawkin I had them for a review after Mr James finished with them. Excellent speakers. My new standard in best sound for least money.

[@svalbard01]

Sucks they aren't making them anymore though. I really wanted to buy some.

[@asfbi]

What's it like to say $2500 bookshelves are the best bang for buck lmao

[@JagadeeshPolepalli]

Can we use audyssey one that we get with AVR? We have 3.5mm port on laptop where we can plug in

[@melcuemba03]

Is it true, I cannot download the OmnimicV2 on my MacBook Pro? REW downloaded but it seems I cannot download on my MAC?

[@fabiozagoo]

Is right the left and right channel play together with sub in measure the low frequencies or only the sub can play ? And how measure each channel individually or all together ? Thanks !!!

[@Audioholics]

Always measure both front speakers + subs to see how they integrate together.

[@derrickmcpherson44]

What about the center?

[@derrickmcpherson44]

So what about the surroundings speakers do those one at a time? Am doing an 11.4 or 13. 4

[@roustamakhmetov2926]

Hi, do you mind mentioning the link to the stand model you were using with the microphone. The one included is not very convenient.

[@tabitharasaproject]

I'm so glad I only have to measure from one position -- my listening/mixing position.

[@asfbi]

Went to buy that mic and found an article about how the quality is so bad that wholesalers are dumping them and recommending umik or Dayton mics unsure what to believe

[@marksclemons]

Hello question for Gene. I want to move from my laptop to something else to store my music. I love Roon & I'm looking to get either a Elac Discover to take advantage of the lifetime roon subscription or something else & purchase Roon yearly. What would you say is an economical way to store my music other than a laptop that's not too costly? thx

[@rodneyarnoldi]

Thank you very much for such an informative video. Can you please tell me why you decided to use the mic at 90deg baring in mind that you were only testing the front pair of speakers? Thank you.

[@charlesmonroe9317]

Is it OK to stream your test sweep via WiFi instead of using HDMI?

[@joegridl]

I can't hear anything. did you disable the sound? I checked and other videos have sound :)

[@Kirk-Monteux-Production]

Good explanation, sucking music.

[@miked5487]

I thought the output levels and input levels need to be roughly the same when measuring?

[@LucianoVeneziano]

Hi! Thanks for the video guide, I have a problem, I don't have the calibration file in the microphone, what can I do? Thanks and great things.

[@jc6993]

I've got questions...

[@fabiojr15]

Can you equalize all HT channels? 11 for example? Assuming you are using a HTPC as audio source?

[@Cakebattered]

I came to hear you discuss REW software, but I'd also like to hear your thoughts on your Philharmonitors.

[@johanakerblad339]

How accurate is the distortion test with UMIK-1?

[@keepingupwiththejones2933]

You put so much thought, time and energy into your videos. Love your work ethic and striving to get better every day
