Christian Budde releases Fast Soft Knee Compressor, Limiter and Gate and Frequency Splitter plug-ins

Christian Budde has released several new free VST effect plug-ins for Windows.

Fast Soft Knee Compressor is a soft knee compressor optimized for low CPU usage. While it is not that difficult to build a hard knee compressor with a low CPU usage, it is quite difficult to do so for a soft knee, especially if you want to control the margin around the threshold precisely while maintaining a consistent curve. The compressor also features a simple limit circuit to avoid clipping.

Features:

• Lightweight soft knee compressor.
• Continuous and consistent characteristic.
• Fully adjustable soft knee in dB (as margin below the threshold).
• Stereo/dual mono processing.
• Extra limit circuit to avoid clips.
• Simple auto make-up gain adjustment.
• 10 presets.
• Mathematically optimised (using three psychoacoustical evaluated approximation functions).
• Open source (as part of Christian's Delphi ASIO & VST Project).

Fast Soft Knee Gate is a soft knee gate optimized for low CPU usage based on Christian's Fast Soft Knee Compressor.

Features:

• Lightweight soft knee gate.
• Continuous and consistent characteristic.
• Fully adjustable soft knee in dB (as margin below the threshold).
• 10 presets.
• Mathematically optimised (using three psychoacoustical evaluated approximation functions).
• Open source (as part of Christian's Delphi ASIO & VST Project).

Fast Soft Knee Limiter is a soft knee limiter optimized for low CPU usage based on Christian's Fast Soft Knee Compressor.

Features:

• Lightweight soft knee limiter.
• Continuous and consistent characteristic.
• Fully adjustable soft knee in dB (as margin below the threshold).
• 10 presets.
• Mathematically optimised (using three psychoacoustical evaluated approximation functions).

Frequency Splitter for Modular Hosts is a Linkwitz Riley Crossover.

Features:

• 1 in, 2 out.
• Selectable frequency.
• Selectable order (starting from 12dB/Oct up to 192dB/Octave).
• Sample-rate independent.
• Using host dependent GUI.

Linear Phase Frequency Crossover for Modular Hosts is a Linear Phase Crossover.

Features:

• 1 in, 2 out.
• Selectable frequency.
• 512 FIR filter coefficients (higher on request).
• Sample-rate independent.
• Fast (using the IPP).
• Open source (excluding IPP).
• Using host dependent GUI.
