Courvoisier is a free dynamics processor effect plug-in for Windows.
"Courvoisier is a single-band universal dynamics processor with adaptive attack and release algorithms optimized for complex program material (mixes and submixes). Courvoisier uses free-form curves drawn over the histogram of incoming audio material (as opposed to traditional ratio and threshold parameters) to determine the transfer function of the processing."
COURVOISIER FEATURES
Histogram representation (sliding-window statistics) of incoming program material and the resulting gain change on which the transfer function can be drawn.
Free-form upward and downward compression and/or expansion.
Spline interpolated control curves.
All performance-critical code optimized in assembly (utilizing SSE2 flow instructions).
Two different adaptive attack algorithms (program dependent).
