Signal Noise SN01-G Compressor

Signal Noise SN01-G Compressor free compressor by Sender Spike

Signal Noise SN01-G Compressor is a free compressor VST plugin developed by Sender Spike. Compatible OS(s): Windows.

SN01-G is a dynamic range compression VST plug-in, inspired by two classic VCA buss compressors of UK and US variety. It has switchable linked feed-forward/feedback topology, with highly variable knee, optional internal side-chain filtering, optional ‘push’ effect, and adjustable wet/dry ratio (alongside the mandatory controls for threshold, ratio, gain, and envelope). The plug-in is designed to work both as musically pleasing buss glue while also being an efficient channel insert with low ASIO/CPU footprint.

Features in detail:

  • threshold from +20dB to -20dB.
  • ratio from 1:1 to infinity (brick-wall).
  • gain up to +24dB.
  • attack in range from 0.03ms to 30ms.
  • release in range from 50ms to 2 seconds.
  • adjustable knee width 0-24dB (0dB = hard-knee).
  • adjustable knee strength (0% = hard knee).
  • 2 optional filters for internal side-chain.
  • optional ‘push’ effect for more extreme compression.
  • dry/wet control for parallel compression.
  • switchable feed-forward/feedback topology.
  • no saturation modelling.
