PIE Compressor was precision-modeled on a vintage PIE compressor like the ones he used in historic sessions at London’s acclaimed Olympic Studios. A mainstay in esteemed British studios throughout the classic rock era, the original PIE processors are considered by many to be among of the best buss compressors of all time. The Waves PIE plugin features a meticulously modeled VU meter with super fast refresh rates that recreates the accuracy, sensitivity, and ballistic behavior of a physical analog meter.
