Royal Compressor Black Friday pricing from United Plugins takes 95% off this vari-mu compressor plugin, so it costs $5 until Nov 29, 2026.
The plugin is inspired by a classic British compressor from the Beatles era. The maker says the original was used on hundreds of records since the sixties.
The pitch is simple: pleasant saturation and sensitive compression with a vintage analogue feel.
It simulates vari-mu circuits, which the maker says add warmth and gentle compression to any kind of audio. United Plugins points to vocals, bass and drums, on both insert and bus channels.
The control set is deliberately short. The maker says a few knobs are enough to get a vintage sound almost instantly.
Because of the AGC, changing the colour doesn't change the output volume. Push the input harder and you can get some serious saturation.
Internally the plugin runs at a high sample rate with 64-bit audio processing. It handles any sampling rate, 192 kHz and above included. The maker says the simulation technology keeps CPU use low.
The interface is a photorealistic 3D hardware look. Drag the arrow in the bottom right corner to shrink it and save screen space, or enlarge it for easier control.
Activation uses licence files. There is no iLok, dongle or internet access required, and you can use it on all your computers as long as you are the user.
A 15-day unlimited trial is available. The maker says it has no saving limits and no noise.
Yes. The Royal Compressor Black Friday deal takes 95% off United Plugins' vari-mu compressor plugin, so it costs $5 until Nov 29, 2026.
On Mac it works in VST2, VST3, AAX or AU hosts, 64-bit only. On Windows it runs in VST2, VST3 or AAX hosts, in 32-bit or 64-bit. Mac needs macOS 10.10 or later, and M1 Silicon is supported.
It switches between three models of circuitry, each with a different value of fixed attack. The maker says the vari-mu simulation suits vocals, bass and drums on insert and bus channels.
No. The maker says it needs no iLok, no dongle and no internet access. Royal Compressor is unlocked through licence files, and one person can install it on every machine they personally work on.
