What Opto Compressor does
Gain reduction in this plugin follows the optical principle: a photoconductive cell reads the intensity of a light source, and that reading changes the resistance that sets the gain. The output amplifier follows the adjustment and produces the compression. The developer describes optical compression as having a special sonic character that audiophiles look for, and it is offered as an audiophile gain control.
The developer states that optical compression is free of distortion and coloration during gain reduction, which is the main characteristic it highlights. Vocals are named as one of the most common applications for the module, and the plugin is presented as a compressor for quality compression work.
Key features
- Optical gain reduction. Gain reduction works through a photoconductive cell that reads light intensity, so the compression is produced by the optical stage rather than by a conventional detector.
- Amplifier-driven compression. The output amplifier follows the gain adjustment, and this follow-up action creates the compression curve.
- Distortion-free reduction. According to the developer, gain reduction adds no distortion or coloration, which is the characteristic the optical design is built around.
- Audiophile gain control. The module is positioned as an audiophile gain control for shaping level without changing the character of the source.
- Vocal processing. Vocals are named as one of the most common applications for the compressor.
- Crack and keygen variants. Searches for this plugin often pair it with keygen, crack and serial terms, and the release is packed as a repack.
