Crossover plugin?
I have installed KXStudio at a professional studio and the head engineer desires a crossover plugin for mixing.
I currently am sending the master stereo out to two busses. One for high/mid with a highpass filter, and one for low frequencies with a lowpass set to the same frequencies.
Is this as good as it gets, or is there an actual crossover plugin so I don't have to worry about phasing issues with the plugin?
Side note, how could I set up a mid/side mastering bus? What plugins would I need?

Re: Crossover plugin?
I don't know of any crossover plugins but there is zita-lrx which a command line crossover filter see: http://linuxaudio.org/mailarchive/lau/2012/2/5/187986. Source code is here: http://kokkinizita.linuxaudio.org/linux ... index.html. You could use it as an insert in Ardour/qtractor etc.

Re: Crossover plugin?
Varpa,
This seems to be pretty much exactly what I need, but I can't see it when I start it. I just need some guidance on how to connect it to my jack client. Any ideas?
It would be excellent if a dev would create a simple interface, or perhaps make it an LV2? I wonder if any other nondevs like me could start a bounty system for much desired plugins?

Re: Crossover plugin?
Look at README.config and the examples directory in the source code to see how to run it. I think a lv2 plugin would be tricky because zita-lrx can handle up to 16 channels and lv2 are usually only 2. I think you'd have to make different lv2 for each number of channels (not sure if lv2 can recreate channels dynamically and also if the number of channels is not 2 you'd need to make special tracks with the same number of channels (which ardour can do).

Re: Crossover plugin?
got me a sub and trying out crossovers. trying out the Calf x-over 2 band LR4 at 80Hz I get a huge gap between ~70Hz and ~113Hz.
anyone has experimented with crossovers recently and can give me some hints?
Will try out LR8 later. would it be better to use the internal low pass of my sub, and put a software high pass on my mains?

Re: Crossover plugin?
I can implement crossover plugin (up to 8 bands) with the LSP suite.
Calf one doesn't compensate the phase between bands, that's why you have issues with the frequency response.

Re: Crossover plugin?
Almost all LSP Plugins that have stereo version of plugin provide mid/side processing analogue. You may try them in your chain.Side note, how could I set up a mid/side mastering bus? What plugins would I need?

Re: Crossover plugin?
I found out looking into older FR meassuerments I always had some issues in the room in that range.
never the less, the calf one is realy limited. can't chose Butterworth. the curves are not adjustable (move close, farer to the crossover frequency).
There is zita-lrx, but I didn't have a look into it yet, since I am still adjusting sub placement. A lsp crossover plugin would be nice
