The Ultimate Mastering Tool
The gold standard in analog M/S mastering compressors - elysia´s alpha compressor is available in a supremely accurate emulation plugin for a fraction of the price of the hardware version.

The hardware alpha compressor is coveted for its professional dynamics processing, featuring innovative functions and absolutely uncompromising sound quality. It set new standards for audio mastering thanks in part to its M/S processing, parallel compression, and highly-responsive limiters and audio filters among other features.

This 100% discrete class-A analog beast provides an amount of openness and clarity unmatched in the dynamics processing world. Every part of its signal processing is based on single transistors running in class-A mode. Even the sidechain and power supply use discrete circuits. All components are of the highest grade available and exclusively chosen according to their sonic excellence.

These benefits add up to an audio quality that is truly unrivaled. Even when extreme settings are used, the sound characteristics stay clean and powerful. The alpha compressor delivers the “this is it” feeling of a finished song. Its enhanced functions far exceed the potential of normal compressors, giving users previously unimagined options for mastering and mixing. No wonder it is considered a mastering studio gem.

Using Brainworx’s advanced circuit modeling techniques, the alpha compressor plugin captures every nuance of its brilliant hardware bretheren and delivers it to your desktop where multiple instances of this beauty are available in just a few clicks.

In addition to the full-blown Mastering version of the alpha compressor, Brainworx, in close collaboration with elysia, has also developed a simpler Mixing version. This version eliminates some of the more advanced features to make it easy to get great sounding compression quickly.

• Provides the most sophisticated and complete set of dynamics control available

• Maintains the character of the original source material even when extreme compression settings are applied

• Transparent, frequency-targeted controls for compression dynamics

• True Emulation

The compression behavior and sound character of the hardware version have been painstakingly recreated to match the analog model

• Oversampling

Increased internal resolution when working with lower sample rates

• Integrated M/S Matrix

As an alternative to standard stereo operation, you can process M/S Stereo (mid and side signals), opening up completely new options for your work

• Feed Forward & Feedback

Compression types can be individually chosen for each channel, making different compressors available with just a button push

• Auto Fast

Switchable semi-automation consistently provides perfect attack and release based on adjustable values – even when working with complex material

• Audio Filter

The Niveau Filter changes the proportions between high and low frequencies for added clarity and punch with zero harshness.

• Sidechain Filter

Onboard frequency selective compression, avoiding the need for complex routings and favoring an efficient workflow

• Parallel Compression

Both direct and compressed signals can be blended as desired

• Signal Matrix

Both the direct and processed signals can be monitored individually or together with the push of a button in each channel (left & right or mid & side)

• Soft Clip Limiter

Tames short and loud transients and smoothens out signal peaks, providing additional headroom and loudness when needed

• Warm Mode

Modeled after the switchable Transformer circuit of the hardware version, the alpha compressor plugin offers very warm and never harsh signal coloration

• Mouse wheel Support

Setting parameters with the mouse can be pretty annoying – for this reason the controllers of the plugin can be moved with the mouse wheel easily

  This is my go-to mastering compressor when I'm trying to glue a mix together. Been using it for a couple of weeks now and I haven't found anything that compares to it.
