Here is some info:
CycoSoft Multiband Splitter/Crossover is a multiple output Windows VST plugin for splitting a stereo input into 2 to 16 stereo channels based on their frequencies. It enables you to route each output to a separate track in your DAW, process them individually and mix them back for a variety of multiband effects like multiband compressors and aural exciters. With the right tools it can be a very powerful mastering analysis utility too. You can also use it as a digital crossover by feeding the outputs to individual speakers.
Basically it's a plugin that I wrote for my own use because I failed to find a plugin that performs the same function. I thought it may be useful for others too, so here it is. It's in alpha stage and it's freeware, you can redistribute it freely if you will. But remember that it is provided "as is" with no warranty whatsoever. Should the plugin prove defective, you assume the cost of all necessary servicing, repair or correction.
The only DAW that the plugin was tested on is REAPER. But it should work for any DAW with similar routing capabilities. So I'm interested to hear from you if it works or not for a particular DAW. Feel free to report the issues on this thread. But please note that I may be a little unresponsive to reports because I'm not a professional programmer but a musician, and I've really got other things to do
Thanks in advance for your interest.
= Features =
* 2 to 16 band splitting, that is 1 to 15 adjustable corner frequencies.
* 32 outputs. Unused channels are muted.
* 64-bit internal processing.
* Very transparent and flat response.
* 24 dB/octave slope.
* 4th order Linkwitz - Riley crossover filters with 2nd order Butterworth allpass filters in the network for phase compensation.
* Hand designed filter network topologies for 2, 3, 4, 5, 6, 7, 8 and 16 bands.
= Issues =
* No GUI yet.
* No 64-bit processing yet. (Internally it _is_ 64-bit, so I may add support for this in the near future).
* Automation is not supported. Well, it is supported but you will hear clicks and zipper noise while changing the parameters.
* Sampling rates less than 40 kHz are not supported. It _will_ crash the host DAW.
* The frequencies must be properly ordered so that f1 <= f2 <= f3 <= f4 <= f5 <= f6 <= f7 <= f8 <= f9 <= f10 <= f11 <= f12 <= f13 <= f14 <= f15. This is not checked in the plugin so you must take care of it. The ordering must be proper for all frequencies even if you use fewer bands.
* The programs are read-only and the included presets are mostly for test purposes.
* It's a bit CPU extensive, so watch your performance meter.
* Splitting to 9, 10, 11, 12, 13, 14 and 15 bands are low performance and may even be defective. For the time being I don't recommend their usage. But 16 bands do work.
= Usage hints =
* Copy the "crossover.dll" file to your VST plugin folder to install. Delete it to uninstall. It should show in your DAW as "Multiband Splitter" by "CycoSoft".
* Avoid applying phase distortion inducing effects (like EQ) on the individual bands. It will cause the sum to be non-flat.
* Although it's very transparent to _my_ ears, the plugin is not linear phase (yet?). But you can achieve linear phase if you want with the following workaround: Just feed it with an impulse, sum all the unaltered outputs, reverse the resulting audio in time. This is your impulse response. Now use a high quality convolver plugin (like Voxengo Pristine Space) after the summing of the outputs. It will cancel all phase distortion caused by the plugin, but will cause (uncompensated) latency. You should recreate your impulse response if you change the frequency settings, and it would be wise to recreate it if you change the sample rate.
* The outputs 1/2 is the lowest band left/right, 3/4 is the higher band and so forth.
