Hi Everyone,

I've released some LADSPA plugins that are loosely based on my VST plugins
I wrote years ago. I haven't produced any documentation yet but most
plugins are fairly self explanatory.

Utility Plugins
* Input Module (Stereo only)
Alter gain, balance, width, phase on a stereo signal

Filter Plugins
* Low Pass (Mono and Stereo version)
* High Pass (Mono and Stereo version)
Gentle high pass and low pass filters

Simulation Plugins
* Tube - (Mono and Stereo version)
Valve warmth/distortion simulation

Dynamics Plugins
* Compressor - (Mono and Stereo version)
Peak/RMS soft-clipping compressor
The 'tight/sloppy' control modifies the envelope sensor - from peak (one
sample) to rms (50ms worth of samples). Having the envelope 'sloppy'
causes the compressor not to see transients at all, which allows for more
severe compression on sounds like vocals & bass.

Reverb Plugins
* ER Reverb - (Mono and Stereo summing In)
Early reflection based reverb. Really more of a room simulator than a
reverb. Use this to add simulated room ambiance to sounds that have none -
particularly useful when combining mic'd & electronic instruments as you
can add room ambiance absent in the electronic signals to help blend in.
Don't expect to get big washing reverbs with large room sizes -  Large
room sizes cause the early reflections to be individually discernible and
you end up with a series of echos.
Another use of this plugin is to reinforce stereo placement - the sound
source is positionable and the resultant reflections realistically place
the source at a specific spot. (rather than dragging the sound back to the
I find slightly off square rooms sound best.

The decision to release as LADSPA rather than LV2 is more due to the host
support of LV2 than anything else. Once LV2 comes out of the RC phase of
it's life and adoption by host applications becomes widespread I'll look
at releasing these as LV2 plugins.

You can grab the plugins from here:

Any feedback, suggestions, hints and criticism welcome.
