Compressor Opto
A compressor is an effect that changes the dynamic range of a signal by automatically reducing
its gain. The Opto Compressor is modeled after a vintage compressor type using an optical circuit
to control the volume reduction of the input signal. These compressors are usually associated with
soft and unobtrusive attack and release characteristics.
