## vSwell

*vSwell* is a volume envelope audio effect plugin. The effect can be triggered by an audio signal, CV or a MIDI notein.

The effect signal input is separate from the trigger signal input. This is *mostly* so alternative signal dynamics can act as a trigger (a fuzz can run through the effect, but the unboosted "clean" signal can be the trigger). However, other unrelated sounds can serve as the trigger, also.
9+
The plugin is provided in two versions:
10+
11+
* vSwell
12+
* Mono, with a separate trigger input
13+
* vSwellST
14+
* Stereo, with selectable trigger channels

Plugins are provided in LV2, VST, VST3 and CLAP formats, compiled for Linux environments. With a working hvcc environment, the patch *should* compile for other systems.

### Mono vs. Stereo
19+
20+
On the mono version the effect signal input is separate from the trigger signal input. This is *mostly* so alternative signal dynamics can act as a trigger (a fuzz can run through the effect, but the unboosted "clean" signal can be the trigger). However, other unrelated sounds can serve as the trigger, also.
21+
22+
The stereo version can select either channel (or both, or neither) as the trigger, and both channels have the envelope applied.
23+
24+
The mono version doesn't always work well with DAWs or other track-oriented applications. Two inputs and one output is more difficult to integrate into an automatic interface.

### Envelope Terminology

vSwell uses the terms outlined on the graphic below for envelopes. The choice of terms is largely dictated by the Heavy (hvcc) compiler, as it only organizes parameters alphabetically. While relatively self-explanatory, here's a visual guide:

* Higher settings for *Threshold High* raise the threshold, and make triggering less likely. Higher threshold == less sensitive. *Threshold Low* is the # of decibels **below** *Threshold High* at which the trigger resets. I.E., the signal must drop by this amount before a new trigger event can occur.

6594
* Setting the SubEnv Level above 0.1 and adjusting the envelope to slowly raise the level can create an effect similar to compression. It's not really compression *per se*, but it sounds cool (adding reverb also is cool).

6796
* The Shape parameter is exponential. When set to 1.0, the envelope curves are linear. Below 1.0, the curves are convex, above 1.0 they become concave (scooped):
