AQ550 (VST, AUv3)

AQ550 (VST, AUv3)

I haven't tried 550b but 550 is doing great in some vocals and piano. This eq sounds fantastic for the price is unbeatable. I have volko which are API but these sound better to me and like the GUI much better. Definitely, going to try the trident.trevon (Gearslutz)

C1-Alpha Compressor v1.1.1

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

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

C1-Alpha 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-Alpha immediately and very fast starts to lower the signal level slowing down by exponential law.

C1-Alpha is not an emulation of any hardware or software compressor. But due to its exceptional characteristics of its audible results, it can be compared to the following well-known compressors: Tube-Tech CL 1B (on «lead vocal») and Fairchild 670 (on «master buss»).


  • Attack mode: «alpha»;
  • 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.
