Every 60 seconds the plug-in will fade to silence momentarily.
To remove this limitation you will need to buy an activation code.
To remove the demo limitations, open the plug-in in your host application and click the lock button at the top left of the plug-in to open the license entry dialogue. Type (or paste) your product activation code into the text box. You will then need to restart your host application to complete the process.





Overview
A versatile plug-in inspired by one of the best-known recording console bus compressors.
Inspired by one of the best-known console bus compressors, the ACM520X1 offers a wide range of settings from gentle 2:1 compression, often regarded as the essential 'glue' of a cohesive mix, to more obvious punch at higher compression ratios.
In addition, a switchable side-chain highpass filter makes it ideal for bass-heavy mixes, without over compression. The ACM520X1 plug-in emulates all the desirable qualities of a professional analogue console bus compressor, taming dynamics without restricting the natural character of a mix or performance.
Presented as a virtual 500-series module with a modern stylized user-interface, the ACM520X1 provides soft-knee compression at low ratio settings, coupled with a subtle analogue style overdrive for warmth and character at high signal levels.
The plug-in can be used in mono or stereo configurations, delivering professional console-grade processing, with efficient use of CPU and system resources.
More efficient use of CPU and system resources allows more plug-in instances in a typical audio workstation project.
- Smooth controls with no 'zipper noise' when adjusting the plug-in settings.
- Switchable side-chain highpass filter prevents over compression of low frequencies.
- Warm analogue style overdrive when driven with high signal levels.
- Physically modelled rotary control modes.
- Resizable, modern user interface. As intuitive and easy to use as a traditional analogue console bus compressor.
- VST, VST3, AAX and CLAP plug-in.
- Windows & Linux compatible.
System Requirements - Windows
- 64bit Windows 7 or newer.
- A compatible host application.
- Linux x86-64/AMD64 64bit e.g. Ubuntu 20.04 LTS or newer.
- An X11 or XWayland compatible host application.
