Tone-Laden Optical Comp, Subtle To Slammin’!

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, like the Shadow Hills Mastering Compressor, the elysia alpha compressor, or the Millennia TCL-2.

But in this case, rather than re-recreating a hardware product in software, the bx_opto takes the best aspects and anomalies from legendary light-dependent Circuits to create a software compressor you wish you could buy in hardware!

Opto Compressors respond differently to different input signals, which is often referred to as being “program dependent”. For example, an opto compressor will react differently to a longer loud part of a song than to a short loud hit in a quiet part, as the photo cells will build up heat over time, which slows down the attack and release times significantly. With opto compressors, everything is moving constantly, and in an ear-pleasing way!

The musical characteristic that optical compression circuits possess, has made them a favorite of professional engineers for decades.

Next level Opto Compression

And Brainworx take the opto-concept to the next level with this plugin. 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.

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).

But hardware opto-compressors can only allow the user 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 itself by allowing users to adjust the speed at which the LDR (Light Dependent Resistor) regains its dark resistance, producing a sonic character impossible to replicate with a hardware optical compressor.

Take a listen and be ready to fall in love with this red beauty.
