KVR Audio

Good news everyone!

QRange, a linear phase IIR EQ, has just been released. It features:
- 12 bands (sortable by frequency).
- Each band can be used as peak, shelf and cut filter.
- Cut filters are available with 12, 24 and 48 dB/oct steepness.
- Stereo/Left/Right/Mid/Side routing per band.
- Global gain for loudness adjustments.
- Resizable user interface.

The plugin for Win/Mac VST2/VST3 and AU is available on kvr.

While the plugin seems generally stable, there might still be some hidden bugs. Please consider it as an open beta for a month or two. This of course also means that any feedback and suggestions are welcome.

Thanks! Will check it out when I get back from my trip.

Very nice and quick workflow, easy to follow where is what and what it does.
Good resolution on mouse adjustments, doesn`t slip away.

Smooth in/out on bypass, a bit juddery on enable/disable (contribution to linear phase I guess).

Routing per band: genius.

Seamless resizeable

(quickly focusable)

Fun: "Sort Bands" replaces bands in numerical order when pell-mell grabbed in the heat of the moment.

I assume latency setting at insane = most accurate (sounds fuller) & short = most cpu efficient.
Up to insane pretty good cpu datas yet, nothing crazy.

I don`t know how to outline the sound ... precise?
Ehem ... the color = a reference to a certain EQ?

Idea: what if bands could have solo run (without disabling 11 others)?

Have to sum first session as such: very nice and quick workflow.
Thank you for this creation, fun all the way.

Appendum:
I see latency datas now (overlooked),
short: 139,2ms up to insane: 1114,5ms, could be a challenge for some.
Acceptable stress test on my system.

Hi,
As tout are looking for feedback : does it feature oversampling?

Some popular features are also :
-dynamic eq
- per band soft saturation
- artificial intelligence : suggesting eq curves

One thing which i like is spectrogram view.
Also, per band soloing would be great to have:)

You want an Izotope thingy for free? That would take quite a long time . . . if he chooses to do it in the first place.

Thanks for the input and feedback.
I wrote a bit about latency on the QRange page.
TL;DR: "Medium" or "Long" ar sufficient in most cases. The latency shouldn't change CPU usage too much but a higher latency allows a more accurate bass response especially when using high Q-factors. "Accurate" here means that with lower latency settings the actual Q-factor and gain can be lower than shown in the frequency plot.
In a test I did a difference was only audible between the short and any other settings. That was for normal EQ settings, of course. No high-Q 20 dB boosts at 40 Hz.

There is no need for oversampling in a static EQ. The only reason an EQ (again: static, not dynamic) is oversampled is for marketing or to avoid frequency response warping at higher frequencies. As QRange uses filters that don't show warping and I'm not much into marketing there's no reason to add oversampling. Also, with blockwise processing doubling the samplerate means four times the CPU usage as the blocksize must be doubled too to get the same low frequency accuracy.

QRange will not get dynamics as this is rather complicated with a linear phase EQ.
Soft saturation and AI features are nice, but I'm afraid I don't see them for QRange either.

Since a request for a band solo came twice: what should a soloed band do?
I can think of either only process the band or only output the signal that is processed (e.g. bandpass for peak filter, cut for shelves).

Who said that i wanted anything?
A developer releases a new product, in beta, and openly asks for feedback and suggestions... So i have listed popular features often asked for on several eq threads in the last months...
I am not asking or begging for anything, be it free or not.
I already have Ozone, by the way, as well as other eqs ( be it linear phase, dynamic, vintage or whatever), so i was just trying to be helpful...

It`s the option I was thinking of and looking for in the first place.
In practical terms, as if disabling all other bands to "zoom in" into a specific one
for a more precise picture of Q setting and amount of boost/cut.

Thanks for the hp details,
the short <-> insane diff is what becomes most audible (heard it as "rounder" on insane)
as described on lower section (had a 50hz boost on dr bus).

I hope to have some time tomorrow for a 2nd round, more likely next WE.
Questions I would have is in how far the max latency does have an impact on rendering
and how the upper regions are performing.
Didn`t hear obvious ear-piercing events at 2k and up so far.

Thanks
Just a suggestion:
If you could add 3 and 6 dB/oct slope filters, this could become the best lp free EQ!
I'm involved in mastering and I've found a lot of vantages with Acousica EQ 3 dB/oct filters...

Funny enough, I'm using the TDR NOVA 2 72dB slope for mastering lol.

I don't know what you do but you can't imagine how much be helpful, especially the lpf... In my opinion using 72 dB slopes is always heretical but if you're happy good for you...

My clients/customers are happy too

In my case it's only for the HPF around 20Hz, it may sound kinda stupid but does it work for gettting of low-end rumble that only masks the rest of the frequency range (reducing the mix translation potential), and make the compressors/limiters distort more.

Gentle LPFs? Mmm, how exactly do you use them?
