Weldroid Courvoisier

Weldroid has released Courvoisier, 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).
  • Adaptive release algorithm (program dependent, scalable).
  • Additional user defined adaptive release behavior.
  • Side chain filtering (low and high pass).
  • MS operation (with support for different transfer curves for Mid and Side channels).
  • Stereo operation (adjustable stereo link).
  • Dry mix option for parallel processing.
  • Peak, RMS and Hybrid level detection.
  • Very low harmonic distortion (THD during normal operation is below -105 dB FS).
  • Lookahead processing for minimizing distortion with extremely fast attack settings.
  • Complex mode (oversampling with a twist)

Courvoisier is available to download as a freeware VST effect plug-in for Windows PC.
