EQ560 VST Free (Win)

This is incredible, put this on Plugin Doctor you will see a very broad light movement at low settings and when the plugin shows +9db/-9db, that's when starts do narrow very fast, the cool thing is that this behaviour is the same for every band, so know that if you need a little more push, try to get to the 9db territory while being very careful from there because it sharpens fast awesome, awesome, awesome eq.Diogo G (vst4free.com)

C1-Sigma Compressor v1.1.1

Red Rock Sound C1-Sigma is stereo and mono audio signal dynamic range compressor and is a stripped-down version of the C1-L1 Vintage Compressor

C1-Sigma has distinctive sound allowing its usage not only for technical purpose of dynamic range compression but also for artistic sound coloration.

C1-Sigma besides main dynamic range compression module also contains limiting module, which allows controlling peaks passing through the compressor, also supports «parallel» compression and M/S operational mode.

When control signal reaches threshold the compressor C1-Sigma starts gain reduction very slowly thus most attack of the signal passes through (effect transient shaping). The curve of signal level change in this mode is similar to σ-function and due to that this attack mode is also called «sigmoid».

C1-Sigma compressor is not an emulation of any hardware or software compressor. But due to the sigmoid attack mode of audible results, it can be compared with the compressor Neve 33609 (on «drum buss»).


  • Attack mode: «sigma»;
  • Saturation mode: «ratio»;
  • Softness of compressor characteristics control;
  • 7 operation modes: mono, double mono, mono with external side chain signal, mid channel, side channel, M/S, linked stereo;
  • Pre or Post Limiter;
  • Internal Dithering;
  • Parallel compression;
  • 4x Oversampling and 64-bit floating point processing;
  • External Side Chain;
  • Gain Reduction CV Output.
