Save me pouring through the search function, is there a particular thread that can easily/simply explain the REW basics for me so i can run some room sweeps to understand my room characteristics? Or alternatively a Youtube video or series that does the same?

 

Appreciate any help pointing me in the right direction.

There are a few on YT that does it step by step.  I cant remember which ones but do a search and they will pop up.  Most of them assume you have a minidsp 2x4 device from memory.

On another note - if its all too hard, you can book in Paul Spencer to do this for you - fee based.  I havent used him but a friend has in the past and thought it was worth the expense.  

I've looked at a few of them over time.
I thought these two newer ones weren’t too bad. 
Done in the “modern” style but both cover a fair bit.
 

 

 

Thanks @MrBurns84 and @PeterB7858

 

I noticed the vids above on the REW website. Time to get my mic out and give it a go

 

Just started playing with REW myself.

 

There are a number of good videos available and I also found this document very helpful:

Hi 

I have Mini DSP UMIks in stock - ex Melbourne if any one needs one.

@wikeeboy I'd recommend Cristian Corsini if you want to get expert help, in the room itself.  He's done my place and @El Tel's in the past month or so and he's a gun.

Yes, I must admit I've been looking at their website and wondering about their audio services. Good to know you have had a positive experience with him.

 

 

If you are using a USB mic, follow the above video

Thanks mate. When the time is right i'll definitely call on expert help. Appreciate the recommendation.

great thread - @mods, should be stickied

 

(edit) - I "reported" my post to request "sticky-ing" by the mods - hopefully it will happen!

REW is such an awesome tool, and we would all learn from good vids etc on how to drive it better.

Agree!! I've been playing around with REW and a UMIK-1 for the last couple of weeks. Couldn't go without it now. You really don't know the impact your room makes till you run a measurement. 

 

The Room Sim function is really handy to plug in all of your room dimensions and get an idea of how speaker placement and seating position change the in room response of your speakers. It really helps to find the most optimised place for both you and the speakers, or if you don't have a choice where everything goes at least you can understand some of the significant room modes you will face.

 

The House Curve and EQ section is really powerful if you have the ability to EQ through Roon, or DSP devices (within active speakers or outboard devices like minidsp).

 

Was just watching this youtube video when you posted....

 

 

@Marc - gotta say - best run forum ever - suggest stuff to mods and it happens - thanks ! 👍

If you want to use Room EQ Wizard (REW), you need a measurement rig.

This requires:

• a laptop/PC running REW software (free) https://www.roomeqwizard.com/
• a measurement microphone - many people use this one https://www.minidsp.com/products/acoustic-measurement/umik-1 , from all reports it seems entirely adequate

• a microphone stand with a boom like this one https://www.mannys.com.au/icon-mb-01-height-adjustable-boom-style-microphone-stand-w-tripod-base. IME the boom is essential for getting the mic in the right spot.

• A long USB cable is also recommended so you can move the microphone around without needing to move the laptop

cheers

For multi channel systems, you need a HDMI cable (and a laptop with a HDMI output too) 

 

@almikelposted this link in another thread, I found it very informative and useful as a reference for measurement targets.

edit:  just realised the link no longer works and I can't seem to now find the doc via google.  I did save a copy but not sure how I could post it or whether there would be copyright issues?

If you’re using Roon DSP and you want measure the results of those changes in REW, this video is helpful.

 

I've done research into REW and Audyssey, and thought I would give REW a go, and purchase a mic rather than use the Marantz Audyssey mic that came with the SR6015.

 

After I do all the measurement and analysis work. I can't find any tutorials on analysing the REW results as far as what room treatments may be required, or more importantly, how I get the EQ that REW produces into the receiver.

 

Should I instead just bite the bullet and pay for MultiEQ-X (sorry, I know this a REW thread).

 

Any suggestions for an EQ newbie will be greatly appreciated. BTW I found the 

"A Beginners Guide to Room EQ Wizard (REW)" by AV NIRVANA on youtube very helpful, among others,  as far as measurement goes, but little on analysis and nothing on implementation.

 

If you want to use REWs suggested filters, you need a MINIDSP .

Just watched “How to use Room EQ Wizard” parts 1 and 2 from the links above. Some great in-depth info there. 
 

Just confirming tho, I can’t load any info from REW to my SR6015, but will need a MINIDSP or similar?

No you can't send REWs EQ file to the AVR.

You need something like a miniDSP 2x4hd in the chain.

Do you have subs?

I mostly use REW and a calibrated mic to see what's going on in the room and to sort out the low end. 

Use the sweeps to see where to place the Subs/speakers/seating to get the best/smoothest non-EQ'd low freq response, and use Audyssey to EQ from there

There's the kicker - REW is such an amazing free tool - but the key is interpreting all of the information provided by REW to then:

• make appropriate informed changes based on the measured results to speaker/sub/listening position or EQ/delay or treatment (best to try one at a time!)
• Re-measure to see if your changes provided the expected improvements - if they didn't, your interpretation of the previous measurements may have been incorrect - you should review your interpretation and the changes you made (eg changes may not be significant enough to see in the measurements)
• If the new measurements provided the expected improvements - yay!
• rinse and repeat for the next room issue you're trying to solve

Taking measurements with REW is easy - interpreting the results is the hard bit

I have one Q Acoustics 2070Si but in the market for another. I have Krix IW-50s and IW-30s, so moving the subs and maybe moving the seating a little will be my options. 
 

As the room is multi-use (ie wall bed on the back wall) room treatment will be tricky, but may be possible to a small extent.

This is by a long, long way a much easier path to take.

 

As you are finding out, REW takes time, effort and with the right gear, to use with an AVR.
