Plugin Boutique offers a 30% discount on Open Compressor from Woodstock Audio, now priced at $85 USD until March 31st, 2026.

Open Compressor is a compressor effect plugin that reveals exactly what’s happening under the hood at every stage of processing. It uses enhanced real-time visual analysis, a confusion-free layout, an easy-to-navigate UI, and clear terminology to help users refine their sound.

The modular approach allows tailoring the topology to the signal. It supports Peak/RMS operating modes, Feedforward/Feedback architecture, and Regular/Optical ballistic (attack & release) models.

Music producers and audio engineers who prefer transparent control over dynamics would use Open Compressor. Its design avoids hidden or automated processes, placing users in full command of their audio.

This deal provides a reduced price on a plugin with extensive features during a specific timeframe. Key features include Threshold, Ratio (1:1–24:1), Attack, Release, and Knee controls.

Regular and Optical modes offer distinct attack/release behaviors. Auto Threshold, Auto Makeup Gain, and Auto Release handle dynamics intelligently.

RMS/Peak detection comes with multiple RMS window options. Feedforward or Feedback detector modes are available, along with Lookahead (0–10ms) for transient handling.

Detector HPF/LPF filters and external sidechain input support precise setup. Stereo processing works in L/R, Mid/Side, and Link/Unlink modes.

One-knob soft Clipper and Limiter include auto-detect and bypass. Dual Odd/Even Saturator has independent drive controls.

Low-Level control enables upward/downward compression. Tone control shapes dark/bright tones, and Dry/Wet mix allows parallel compression.

Oversampling modes are 2× (Low) or 4× (High). Visualizers cover Waveform, EQ, Knee, Harmonic, plus Oscilloscope and fullscreen waveform view with zoom and pause.

GPU-accelerated graphics, dynamic window resizing, built-in preset manager, and analogue compressor emulations are included. Global and per-module bypass options aid A/B comparisons.

Input/Output/GR VU metering and Delta listen mode provide monitoring. Value typing, hover readouts, and low CPU usage ensure precise, efficient operation.

Available in VST3, AU, and AAX formats for Windows and Mac. More information: Woodstock Audio
