SMAC is a Stereo Musical Audio Compressor (or two channel mono) that uses optical gain reduction cells (two per channel or ‘dual-servo’) to perform quality transparent audio compression, peak limiting, and automatic audio leveling control.
Due to the dual-servo optical based design, the dynamic behavioural characteristics of SMAC lie somewhere between the classic Optical type compressors and the later VCA type compressors. Depth, image, and sonics are all preserved while the dynamics and transients of the signal can be contoured and manipulated to suit any tracking, mixing, and/or mastering requirements.
