Compressors & Limiters

Compressors and limiters are essential dynamics processors used throughout recording, mixing and mastering. From early valve and variable-mu designs to FET, VCA and optical circuits, hardware compressors have shaped the control, punch and tonal character of recorded sound across decades of studio production.

This archive covers both vintage studio compressors and modern hardware designs, including faithful recreations and contemporary interpretations of classic circuits. From original units produced in the 1960s and 1970s to current production models and replicas, these dynamics processors remain central to professional studio workflows.
