Hi,

while crawling through KVR posts I found this:

Juanjo wrote:What I'd like, it doesn't exist in vst form that I know of, and would be incredibly useful for all sorts of things, would be a high quality, multi-mode, multi-slope, frequency band separator/crossover:

- 1 input to 2-to-5 outputs
- [..]

Although not exactly what the original poster had in mind, I clicked my way to a Linkwitz-Riley crossover.

Features:
- 1 in, 2 out
- selectable frequency
- selectable order (starting from 12dB/Oct up to 192dB/Octave)
- samplerate independent
- using host dependent GUI

Enjoy,

Well, there's already Crossover 3-Way from rs-met:
http://www.rs-met.com/ (Freebies section, scroll down a bit)

Which is basically the same concept as your plugin but maybe a bit more advanced... not to shot down your plugin, just pointing it out...

The "novelty" in the idea I was trying to explain in my original post would be:
- The multi-mode part, i.e. a range of filters to choose from, per band
- The manual latency compensation i.e. a simple control per band where you can adjust the delay applied to the rest of bands (in samples). To make sure that you can re-sum the different bands correctly after processing even if pdc is not available or isn't working as expected.

Oh and btw, thanks so much for all the open source software you've published lately... actually when I saw your Split Plugin Creator, I thought it would be very useful if instead of having to generate a new vst out of 2 existing vsts, it was simply an actual VST plugin that splits the incoming signal in two, to be used in modular hosts much like this freq splitter but with the extended options... but somehow I never got around to suggest it...

There's also the AraldFX freeware crossover

Code: Select all

AXV5 for PC. Free 2-5 bands crossover VST Plug-in for all the modular and semi-modular hosts, including Ableton Live, Bidule, Energy XT, etc..

In contrast to both above mentioned this plugin uses the hosts default GUI. Also it has steeper slopes.

Btw. I uploaded the latest optimizations to my server. It now uses 50% less CPU.

couldn't you do this stuff yourself with a splitter plugin, a clean multimode filter, a basic sample delay plugin, and a mixer plug?

Exactly what the doctor ordered!

Thanks Christian

..

**edit**

Wait a f'n minute..

Reading all these 'theres splitters already' posts. WTF? real appreciative guys

!

How do you even know how its going to sound and operate in comparison to the others? If you read the find print you'd see that its the only one with that level of slope cutoff. YES you can build this yourself but at the same low CPU cost? I dont think so.

Plus its free, it probably took a lot of hard work and thought to get it working transparently. I'd probably be a little more understanding if it were say another compressor or reverb as there many a freeware plugins but theres not many freq splitters (actually I wouldnt). Also what if someone wanted to learn this DSP via the sourcecode? Wouldnt be much incentive for a dev to offer up with those kinds of bs comments.

If you have nothing good to say just stfu next time.. SHEESH.

Hi,

just want to let you know, that I just fixed a minor denormal issue.

I didn't mention other freq splitter plugins, I just mentioned that you can do the same thing by duplicating the signal then filtering it.

Hi Christian! thanks for this!

any chance for a stereo version?

this could be very useful...

Thanks,
midi.

It would only take me some minutes, but why would one need this can't you just use two instances?

Hi Christian,

Well, in a fully modular host two mono instances might be equally simple to use as a stereo one, but Since I'm a Nuendo 4 user, applying a single stereo instance into a Quad channel is by far easier and more elegant way when splitting up stereo signals.

So, a stereo version would be fantastic for the non modular host users...

Thanks,
midi.
