03In depth

Optical compression character and sound

Optical compressors use a light source whose intensity follows the incoming signal level, and a photoconductive cell that reads that light and changes the gain applied to the audio. IK Multimedia says Opto Compressor models this movement faithfully, reproducing the musical feel associated with the best optical designs.

The developer emphasizes that optical compression is free of distortion and coloration during gain reduction, and that this digital recreation aims to deliver the same character and performance. The result is compression that is intended to be gentle yet effective.

Typical uses for an optical compressor plugin

Vocals are a common application for Opto Compressor, since its gentle yet effective gain reduction suits steady, expressive performances. The developer also states that the plugin can be used on any source that needs clean, steady gain reduction without distortion.

Because it is an effects plugin in the compressor subcategory, it fits anywhere in a mix where you want level control on individual tracks or buses.
