Chun-Yu's Smooth Overdrive Effect 1.1

This plugin is pretty simple. No parameters or attributes. Just use it for a cool sound, especially when you hook it up to my TouchWah effect (but be sure to use the ScaleFactor or it'll clip!). What this plugin does:

Overdriven data is produced by
Sin transform (mapping the amplitude to the Sin curve between 0 and PI/4)
Quantize -> 4-bit
Ln transform (similar to Sin transform, but different. I somehow came up with this one day while writing a Winamp DSP plugin)
Quantize -> 3-bit
then, (sqrt(overdriven*original)+(overdriven+original)/2)/2

The square root part takes the proper sign from the original WAV data.

The Sin and Ln transforms each use tables, so they shouldn't use too much CPU time. I know the last stop does take some CPU time, and I'll try to fix it soon.

New in this version:

1. Supports Stereo input.
