your hair is amazingly textured

awesome video and presentation

Thank you for making this, extremely helpful!

My impulse & rt60 & everything looks different from your's.

I would have liked to see the "Clarity" measurement feature because I'm trying to improve our church speaker positioning issue.

hey , did u move big tall bass trap in the corner of fronwall to avoid sbir ? thanks ?cant see any finnal picture about front wall ...

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?

If i dont have an audio interface, can i use a di box?

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

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.

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.

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.

Oh...wow. Thank you SO much!!!

thank you! For the speaker placement tests, were those done with a single speaker?

hey guys, what if i don`t have an calibration file of my microphone? I have the measurement microphone from Ik multimedia arc 2. The one with the orange ring. I guess I could use that, but I have no frequency response file or documentation. Any ideas ? th-cam.com/video/PeVPql6Y3rM/w-d-xo.html

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.

Awesome simple explanation thank you!!!

great informative video, part 3 please!

Great job. Really appreciate ur knowledge and understanding sound, acoustics, REW... how to contact u... we have a project to discuss

Super helpful. Will come back when I have my measurement mic and my gear set up. Greta delivery of information for a relative novice like me but its all starting to make some sense! Many thanks- I'll be back!

Having calibrated the sound card, it is necessary to remove the loopback cable and connect a mic to the same port input as the output 1 is a speaker.

Hey this looks great thanks. My ADHD means I can’t focus on your voice with the music. I could see it without the music so that was good 👍🏻

Part 3 please!!

Great video! I have been looking for someone to really explain how to interpet the data and you do a great job of that! :)

Thank you.

Question: and how do you know that these deviations are of the room and not of the speakers. almost all commercial HiFi speakers have +-5db response deviations

I totally agree, by far the most detailed and easy to follow video I’ve ever seen on REW. STEP TO THE HEAD OF THE CLASS. 🎉❤

This needs to be updated to accommodate for the newest updates to REW

Thank you so much, one of the best video on the REW tool. Looking forward for part 3

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.

Yes please how can I measure clarity ???

Very interesting discussion. Square rooms are just no fun for acoustic balance. People always complain how they've spent thousands on absorption, yet hear little improvement. I always recommend large false wall panels 4" from the real wall to essentially "reframe" the geometry of the room, addressing the room modes and and standing waves. This also secures a healthy air gap built into the room.

how to use the exported EQ filter wav in a DAW like cubase?

Legend!

Very helpful! Thank you!

i plan to do large room/ worship halls measurements, yes, please do part 3 of this series, hopefully focusing on a typical worship hall measurement. the series is very helpful. 🙂

I've got a question that I've wondered for such a long time with this video and with Jesco in particular... From 80hz down, why do studios that fall under the small-room-acoustics umbrella not employ a multi-sub approach to flatten the FR of the bass and then use treatment to take care of the decay time? For that matter, if you have your subs mounted directly under your monitors, you could even extend the multi-sub benefit higher to 120hz-150hz... maybe even higher? I've got zero treatment in my 18x19x7ft room and can shape the FR of my subs to whatever I want it to be with my multi-sub (only 2) approach and Dirac Live. This was after optimizing my seating placement and sub placement.

Great tutorial. Thanks a lot!!!

I've got 16 panels in my room. It's a hobby. I build my own. Without these videos I would not be where I am today. Thanks Graham and Jesco!

Oh an SPL meter, we all have that

Great video! Im interested in membrane traps. Can you tell what type of material is using as membrane ?

@ Music City coustics: You are showing everyone that you really know nothing about acoustics. But as Alice in Wonderland asked the Cheshire Cat, “Would you tell me, please, which way I ought to go from here?” “That depends a good deal on where you want to get to”, said the Cat. “I don’t much care where-” said Alice. “Then it doesn’t matter which way you go,” said the Cat. If you don’t know where you are going, it is highly probable that you will never get there.

Thanks for the video! I see in the comments a couple of people ran into the same issue that I did: everything seemed to be set up properly but REW isn't getting the input. Check the privacy settings on your MAC and make sure REW has access to the microphone (even if using an external audio interface)

i missed something. the loop back? i dont not have a sound card, but a usb codac. what i do from here ?

The calibration file for my microphone is not available. Can I generate the calibration file for it with REW?

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.

thanks for this one! so many videos so badly explained. I wish REV would make the resulting graph a readable graph to start with! what is the point in featuring the overcomplicated not really usefull grahp first and force you to make multiple adjusments when we all know 99% of us will like to get a base line (!) and easily readable the amount of dbs over and under, easily seeing dips and peaks. As now you have to start making changes all of the time and comparing points values and counting, whyyyy? I thought the principle is present first the simplest most useful version and then let advance needs and users look for the other parts. ...

thanks a lot. this is very helpfull.. got things to do
