  Stereo Gate

Got the PCI rme card today. It's working great in the dual opteron. I've plugged in some new devices - my old korg and a mic and a PODXTLive. I have a mono gate for the mic, that's cool.

I have been thinking about doing something odd - as the korg doesn't generate enough volume to crack -20 db, and I have been clipping my final mix a lot, I'm thinking to myself - would it hurt to just record linuxsampler and hydrogen at -20 or even -30 db? I have the headroom... why stick all these compressors inline, peak at -3 all the time, have to master it down, when I don't have to? I have at most 60db of dynamic range right now (though I intend to really fool with that with some very quiet environmental noises).. I'll have to research this...

Problem is, when I try that on analog sources, the gates go screwy (no gates needed for digital sources), they cut in at levels hat are musically sound for 44.1khz/16 bit running hot levels, but not this. maybe I should do all the digital stuff at low levels and the analog at the usual hot...

After scraching my head for a while, (there are no stereo gates in the ardour2 ladspa plugin list for some reason - I wanted to click on "Gates" and have a stereo gate to play with, I don't see one, neither would a first timer), I finally found that the Tap-Dynamics plugin has a stereo gate, and a fairly easy way to compile in new functions, if I so choose.

It's cut-in is fixed at -80 db. And it doesn't clamp down to 0 at below -80 db, either, just to -105.... -infinity damn it! Or whatever the value for 0 volume is supposed to be.

I'll try compiling in a better one.

Still, what I want is something with knobs I can tweak dynamically, got lots of noise down in the mud on the mic, korg, and podxt (supposed to be noisy, it's an amp simuation, but still...)

There is a stereo gate in Steve Harris's plugins, (plugin 1922), but it's not compiling in by default. From looking at it, it doesn't seem like it could possibly work, either.
