Software lkjb releases QRange

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 can be downloaded on kvr. A bit further information is also avaiable on the QRange page.

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 IKJB , great sounding free plugin!
It's great that you can select the style for each band, works fast!

Some ideas that could make it even better:
a non linear phase zero latency mode (if possibe)
A changing q by ctrl dragging for even faster working

Keep up the good work!

tried it today and have to thank the dev for such a great free EQ. never really use LP equalizers even if I own several but have a crush on this one tbh. the smoothness in the upper mids/highs is lovely. the features (save as default, gain range etc) are excellent. keeper!

one thing: adjusting the q sometimes makes it jump to the tightest value. no biggie but worth mentioning

Surprisingly great UI. Very convenient to use.

Since the default Q creates Linkwitz-Riley filters, high cuts and low cuts can be used to split up a signal and recombine with no humps or dips at the cuts. Could be handy.

I don't have current plans for a non-LP mode. Not a "no" but at least nothing for the near future.
What do you mean by ctrl-dragging for changing q? By holding "shift" you can already fine-tune parameters if that's what you meant.

How do you change Q, e.g. using mouse wheel inside the graph, dragging the band's control or entering a number? Which DAW and OS are you using?

If anyone's interested, I wrote a bit about IIR-based linear phase EQs here.

It happens when I click drag the numeric field of the Q factor (unless I do it suuuuper careful/slow it instantly jumps to 18.00)

Nice article. I was going to ask if you'd add 6db cuts, but now I see you can't.

The "no pre-ringing" joke I wonder how this compares to the recent $1k plugin... lol

Compares to maat's thEQorange and forthcoming thEQred?) if free QRange by lkjb works fine, no need to buy overhyped old-coded plugins with price of hardware and protection sh+t. If something costs 10-50 times, it doesn't mean it is 10-50 better, maybe it is not better.... If not worse. Who of earbuds/phone-listening mp3 fans (usual listeners) cares about phase and transient smearing, dithering, src...

Ok thanks for the reply.

My suggestion/ question was more like , when you grab the frequency with your mouse and move it up or down the gain goes up and down. You can use the scollwheel for narowwing or widen the q, but is it also possible to implement the use of ctrl for that function? So when you hit ctrl the gain freezes and the q gets adjusted when you drag you mouse up and down?

I have an old school Microsoft mouse, so with an ergonomic mouse it propably would be better… but my fingers feel a little bit cramped of using the left button and the wheel at the same time.

Anyway again, great plugin, thanks for all your efforts!

could somebody make a comparison between QRange and thEQorange? This will decide once and for all if the last one stands to its $999?

I just released an update with some UI changes, match gain and band solo.

I missed this suggestion but will try to add it in a future update.

For what it's worth, I prefer the free ikjb Luftikus EQ to the official one, so I bet this one also compares favorably to other emulations too.

Thanks.

Btw, I can't seem to find any download links for any plugin. Anyone else having this problem?

A minor update whichs adds presets, shows whether a gain match is possible and allows changing Q-factor by ctrl-dragging a handle is now available.

The download is available via kvr audio where I host all my plugins.

Pretty cool. I don't think I've ever heard an IIR based linear phase eq before. I've been looking at/listening to samples of the Maat one and it does seem like this is in the same family. Crazy times we live in.

I have to thank the developer.
This is really great Used it to crossover a bass Di mult to create a bass-body channel and a separare mids-grit Channel with different slopes . worked like a charm and the summed output sounded great.

Wouaou man, this EQ is outstanting . The only problem is the CPU Load and Latency. BUT, what a sound
Push the 12Khz at 12db and the drum is shining like no other EQ could do.

And it's Free

Even if it wasn't, is anybody know which other EQ can give that sound ?

I just release version 1.1.0 which includes a latency free but non-linear phase mode which is also lighter on the CPU. Downloads are available via kvr product page as usual.

Isn’t Crave EQ IIR based? That has a linear phase mode.

Cool, I just give a try, and the sound is very closed to the Long Latency.

It's an amazing EQ

How did you do that and why do you propose it for free ?

As the EQ simply processes a block of samples by a normal EQ forwards and backwards the changes to implement the normal EQ behavior were quite simple as I only needed to add another stage with the same settings. That's also the reason that the sonnical difference is rather subtle as the only difference (as long as the EQ parameters stay in a certain range) is the phase response which humans won't hear directly. I hope the explanation is not too technical.

Plugin programming is a hobby for me. Taking money would not only put some pressure on me to solve issues quickly (I think I'm not doing that badly here but still at my pace) and at some point would involve filling out tax forms which certainly is not one of my hobbies.

Brief testing on my home computer:

- CPU doesn't change, no matter what latency I select.
- Saving default settings doesn't remember latency and band type (I selected a high shelf and it went back to bell).

Just so you know

The CPU usage shouldn't change too much with latency unless the non linear phase mode is chosen (which should be more CPU friendly). You probably didn't see a difference because the analyser was enabled which is rather CPU intensive (band based instead of FFT).

I also noticed the band types and latency setting not being restored correctly for defaults and release an update (1.1.1) about half an hour ago. The update also includes an option to not process the analyser while the user interface is closed which should help a bit CPU-usage wise.

Hi!, thanks for this.

It's working pretty buggy in Cubase Pro 10 @ Windows 10.

Would love having narrower Qs, which i would choose for a transparent EQ

Thank you,
Daniel.

Hi!, just changing to minimum phase freezes Cubase, or bypassing the plugin mutes the audio for that channel.
