Hi folks,
I'm seeking a little information in setting up parametric EQ filters calculated from REW. This is my first time at this caper and I'm not particularly well-qualified to do what I want to do.
Anyway, I've acquired EQ files using REW for L, R and L&R combined at my seating position and I exported the L&R combined file using mini-DSP format (44.1KHz). This was successful and the music plays (through my Wadia di122) very nicely. But I have two questions. As my L and R eqs are a little different to each other I was wondering whether I could load each file separately into MC31 so that I can eq L and R separately rather than have a combined eq, which I guess will be a compromise for each channel. In addition, the format for export from REW implies 44.1 KHz frequency - what happens if I play a recording with high resolution? I have tested a couple of tracks at 96 KHz and they sound fine, but I'm more of a cloth ears than a golden ears, so I may be missing something.
Any advice would be greatly appreciated!

Yes you can eq each channel individually
https://yabb.jriver.com/interact/index.php/topic,129609.0.html supports import from rew to MC without requiring the use of a raw biquad export (which is frequency dependent)

Great, thank you for the advice, you've done a fantastic job developing that app! I think I'm confident enough to follow your instructions, but I still have a question. In the DSP section of MC I can only see a way to import one PEQ filter, which is why I chose to import just a combined L&R filter. I can see two buttons to activate PEQ; is that where the L and R individual filters are input or is there a setting in another page that allows assignment of L and R? Or does the filter file itself specify whether it is for L and R?
Also, when you say biquads are frequency-specific, you mean that they must be set up individually for each source frequency - 44.1, 96 etc?
Thanks for your time!

I don't know where you see that, you can add as many filters as you like. Best to show a picture of what you're looking at.

I'm saying don't try to import biquads, just add the filters directly

Bingo, all works very well, thank you for your assistance and perseverance!
One final question - a rather heroic set of filters was produced by REW, including a pair quite close in frequency one a boost and one a cut. With my old Behringer GEQ they advised against having cut and boost in adjacent sliders. Is there such a principle in operation with the more modern PEQ software?
Thanks once gain for your time!

There is no problem doing that, rew does tend to produce such filters as it lets it shape things in a certain way. I assume you're using the generic filter type in rew for use with jriver?
-
Yes, generic filters. Thanks for the reply, that puts my mind at ease!
