Fircomp Free Clean Compressor Plugin

Fircomp Free Clean Compressor Plugin

Fircomp is a free VST/AU compressor plugin by Jon V Audio, described by its developer as a “compressor with perfect curves”.

This is a clean compressor with punchy attack, musical release, and optional lookahead smoothing, for tracks or busses. It has low to zero latency and low CPU, and delivers a warm distortion at extreme settings.


  • Simple UI and fast workflow
  • Attack stage tuned for punch. True zero attack (same-sample) when “0.0 ms” is selected
  • Dual parallel release stage with musical, highly program-dependent behavior. Avoids needing to use multiple compressors in series!
  • Easy sidechain filtering options for common mixing situations
  • Optional smooth digital FIR lookahead gain smoothing with perfect timing and no artifacts, resulting in the minimum possible distortion
  • Low CPU DSP code written in a mix of C++ and SSE intrinsics. Insert on every track without a second thought!
  • Fully 64-bit audio path used for all DSP calculations
  • Zero-latency with look-ahead off. With lookahead on, compensated latency of 64, 128, or 256 samples depending on sample rate (approximately 1.3 to 1.5 ms)
