SoundRave is giving away its compressor plugin Quanpressor for free for a limited time. The plugin normally sells for $12.99, and the giveaway runs until August 22.
In this article we cover what Quanpressor does, its main features, and how to claim and activate your free license.
What Is SoundRave Quanpressor?
Quanpressor is a compressor plugin that packs four classic compressor characters – FET, OPTO, VCA and Vari-Mu – into a single instance. All four modes share one common control set, so you can switch between compression flavours quickly without relearning the interface each time.
On top of the four modes, it adds sidechain filtering, automatic level matching and a full set of visual meters, so you can dial in compression precisely rather than by ear alone. It is a genuinely useful all-rounder to have in your mixing chain, especially at a price of zero.
Key Features
- Four compressor modes – FET / OPTO / VCA / VARI-MU – each with its own attack, release and compression character
- A shared control set covering Input, Threshold, Ratio, Attack, Release, Knee, Makeup and Output
- External sidechain input with an EXT SC switch
- High / Low spectral preserve controls for shaping detector sensitivity
- Auto Level Match, plus loudness compensation when switching between modes
- GR Match, which automatically adjusts the threshold to match the previous gain reduction average
- Input/output meters, a gain reduction meter, a transfer curve display and a scrolling GR history view
- Dedicated time constant buttons for the Vari-Mu mode
- Supported formats: macOS (AU / VST3) and Windows (VST3)
