Overview

The Brainworx bx_opto compressor combines some of the best colors, character and features from what Brainworx has learned modeling the optical circuits of some of the world’s best-loved compressors. Rather than recreating a hardware product in software, the bx_opto takes the best aspects and anomalies from these legendary light-dependent circuits to create a software compressor you’ll wish you could buy a hardware version of. The result is a beastly little dynamics processor, teeming with character and spitting out sounds no analog optical compressor can.

Most optical compressors are appreciated for their musical, program dependent character introduced by anomalies in the light dependent circuitry of the sidechain; the general speed of compression is cemented by the given behavior of the compressor’s Light Dependent Resistor (LDR). Hardware opto-compressors can only allow users the ability to adjust the effect of this character by introducing a separate resistance circuit that gives some control over the compression envelope.

After intense experimentation and listening tests, Brainworx found a way to adjust the compression envelope by allowing users to adjust the speed at which the LDR regains its dark resistance, producing a sonic character impossible to replicate with a hardware optical compressor. Combine that with the sweepable sidechain filter (20 Hz – 20 kHz) and you have a potent way to smash and pronounce your way to a most unique sound.

The end result is a compressor that can beautifully perform seamless dynamics management or create dramatic compression effects. The musical characteristic that optical compression circuits possess, that is, responding differently to different input signals (often referred to as “program dependency”), has made optical compressors a favorite of professional engineers and producers for decades. The Brainworx bx_opto not only delivers that musical quality, but opens up new sonic possibilities with its variable speed knob, simulating changes in speed at which the photo cell in an optical compressor reacts to light. This gives you control over release times that shape transients in such a manner no hardware optical compressor can match.

Features

  • Analog, optical compression colors with more control
  • Content-dependent peak reduction / compression with one knob
  • ‘Speed’ knob controls the coefficient of Light Dependent Resistor, creating unique transient response
  • Fully sweepable (20 Hz – 20 kHz) LP/HP/BP (wide)/ BP (narrow) sidechain filter 
  • Wet/Dry mix for parallel compression 
  • Accurate metering for reading amount of gain reduction
  • NOT a transparent compressor; gently level or completely raze your sound with harmonically pleasant results

    I find myself using this on bass guitar habitually. It adds a presence and clarity that is completely its own.

    Opto
    by Bryan P
    Great sounding compressor ! The speed knob and sidechain filter make it works on almost every sources !
    It's a pleasure in recording session because of the AAX DSP compatibility for he users

    OPTO is optimal
    by DMGJ
    Absolutely instant great sounding compressor. Side chain feature can produce some very interesting sounding drum compression. Mix knob is always welcome and it's very useful when compressing drums… Read More

    he most spectacular COMP for my mixes. I can use to create atmospheres and realistic sound from old machine ( Kawai K1r, K3m, Roland R8, etc), without need to have any musician… Read More
