Roon Room Correction- Who Has used it? Opinions please!

Hi! If it's not consider spammy, I am selling a fairly cheap room measurement mic ($40) that I used in conjunction with this step by step post via the Room forums. Listing should appear on my profile. Did a great job and got me about 80% dialed in from the jump. Just made slight adjustments along the way. Was incredibly helpful

yyz,

Thanks. I heard it employed by someone who was qualified in its use

on a pair of Buchardts. The result was jaw dropping.

If you use ROON and want a pro to do the DSP for you remotely for your room (after you measure it). You use some free software and a decent mic for about $100 to measure the room via guided instructions.  

Digital Room Calibration Services, Convolvers, Headphone Filtersets (accuratesound.ca)

The end result is called a Convolution Filter. This is a turbo charged DSP implementation for your room, your gear, and your seating position. The Convolution filter runs on your ROON Core. If you use JRiver it runs on that.

Since this filter runs on a computer there are no limitations on what it can do, unlike DSP built into some gear, such as a preamp.

Highly recommended by me.

Roon equalization will allow you to adjust frequency ranges up or down, but it has no way of telling you which frequencies to adjust.  I don't know of any way to plug a microphone into the Roon software.  

You can use Roon's DSP based EQ without any microphones, however if you want to do actual room correction with any sort of automated algorithm then a mic will be required.

AFAIK, you need to get a mic and measurement program to see what the response is. Then you can enable EQ in Roon to change it (say to eliminate nulls). At present, Roon is not a complete solution, as it neither measures nor generates the filters used to perform DRC. It will take filters and apply them.

I have used its EQ for other purposes and found it quite good.

I haven't done it, as I am rather old school and don't want to introduce unknown/unwanted time smears to my music.

I do know that many have used a mic for calibration. 

As for software, some use apps on their smartphone.

Please don't think I am a Luddite, but digital room correction is not a panacea for all the sound reproduction issues. It masks obvious issues, but in the end, is not the cure.

If you are looking for a simple sound correction for issues with a simple (non critical listening) system. Roon correction should be an easy way to go.

But, if you are really serious about sound reproduction, I would advise against it.

My 2.4 cents
