Audiffex U73b Compressor - Emulation of Vintage Telefunken Broadcast Processor

The U73b Compressor from Audiffex is a plug-in that models a vintage German broadcast compressor/limiter. Between the 1960's and 1980's, the original Telefunken U73b unit was often found performing mastering duties with its all-tube, variable-mu circuitry and adjustable release time options. The software simulates the original designed with its VU meter and switchable side-chain high-pass filter, with only input and output gain controls added before and right after the compressor circuit to facilitate compression adjustment.
