Overview

The mpressor plugin is the perfect tool for modern dynamics processing.

In addition to great-sounding standard compression, this compressor provides several creative functions that produce fat and freaky sounds with punch, beautiful coloration, and extreme processing effects. The mpressor is equally at home compressing tracks or busses in a mix or while tracking.

The original concept behind the hardware mpressor was a more affordable version of elysia’s flagship, the alpha compressor. But producers and engineers who loved their alpha compressors encouraged elysia’s designers to go for something different and creative, something capable of producing compression effects no other compressor could achieve, including the coveted elysia alpha. The result was the mpressor, a uniquely creative dynamics tool.

Each linkable channel of the mpressor offers a switchable Auto-Fast function that allows for very fast yet distortion-free compression without any artifacts. The Anti-Log circuit generates powerful compression effects such as pumping and breathing. With its true feed forward design, the mpressor allows negative ratios, which can deliver extreme over-compression effects.

The included Niveau Filters can easily shift the character of a track from subtle to striking with the option of continuous frequency shifting. The mpressor is a compressor you have to hear to believe. The plugin’s novel Gain Reduction Limiter lets you choose the maximum amount of allowed Gain Reduction with the twist of a virtual knob.

Using advanced circuit modeling techniques, Brainworx faithfully emulated the all analog, all discrete circuit design of the hardware mpressor, right down to the single transistor signal processing and permanent class-A mode design.

Features

  • True Emulation

The compression behavior and the sound character of the hardware version have been faithfully recreated to deliver all the mojo of the analog model.

  • Extreme yet Tight

A lot of compressors sound good only when used sparingly, and fail to deliver pleasing results at extreme settings. The mpressor’s focused, high-end class-A sound maintains the character of the original audio, even when the most extreme settings are used.

  • Killer on Drums

While the mpressor works great on many sources, it is particularly loved by engineers for its ability to deliver punchy drum sounds

  • Gain Reduction Limiter

Rather than limiting audio in the signal path like traditional limiters, the mpressor’s unique limiter restricts the virtual control voltage of the plugin itself, not the audio signal. This allows users to place a cap on the total dBs of gain reduction regardless of how far the input signal is over the set threshold.

  • Negative Ratios

The characteristic compression curve bends and goes back down! This makes available heavy pumping effects, backward sound effects, and other unique and useful compression effects no other compressor can achieve.

  • Audio Filter

The mpressor features an easy to use, very flexible niveau filter, which works on the proportions between high and low frequencies. The principle behind the niveau is quite similar to a pair of scales: Dependent on the gain setting around a variable center frequency, the high frequencies are boosted whereas the low frequencies are attenuated (or vice versa).

  • Oversampling

In order to achieve the best results on lower sample rates, the mpressor plugin uses an increased internal resolution at 44.1 and 48 kHz.

  • Mouse Wheel Support

The controllers of the mpressor can be moved with the mouse wheel.

    Blown away by how this compressor can compress. (And I’m a compressor addict!) I can have this compressor act beautifully with a vocal track or absolutely smash — and color — a drum buss.

    Seriously good compressor on the master channel. I use this for sorting out my mid/sides. It really controls my sides and keeps all the reverbs in place. Amazing plugin!
