The Protector: Limiting Compressor is part of a new line of plug-ins developed by Acidgrooves that feature the Acidgrooves Entropy Technology. This patent pending technology brings to the Audio Plug-In world one of the characteristics of analog hardware that provides them with some of their unique sound qualities: the passage of time.

With time, capacitors, resistors, transformers and other analog components will decay and lose some of their original specifications which will effectively change the sound and personality of that particular unit. Our technology tries to recreate exactly that.

Introducing The Protector: Limiting Compressor.


The Protector was designed by our team to provide with you with an easy way of controlling the maximum output level of any channel. At its heart lives a transparent compressor which only kicks in when the signal exceeds your specified maximum output level, bringing your signal back to usable levels.

This compressor was designed to maintain the dynamic energy of your sounds and to provide you with a transparent alternative for limiting any channel output.

Features Summary

The Protector was built for those professionals who need a fast and easy way to control the final DB level of any channel while being certain that the signal will remain transparent.

The Protector features a truly clean compressor, input & output meters, a compressor activity led, and up to 64x high quality oversample.

Powered by a cutting edge detection algorithm and a transparent compressor The Protector is meant to live at any channel that may exceed a certain level and maintain it below, while keeping the dynamic energy of its contents.

It was designed to be low on CPU usage, in order to live on as many channels as you need.

Its full range of compression and precise detection algorithm will provide you with the peace of mind that any channel will never exceed your specified output level.

This plug-in features Acidgrooves patent pending Entropy Sound Technologies: Time Arrow Decay (TAD) and Unique Sound Processing (USP) which will allow the plug-in to change its sound as it gets older.
