The BSS DPR-402 from Waves is an accurate software model of the hardware BSS DPR-402 dynamics processor, a long-time favorite of studio, live, and broadcast engineers. The dynamics processor is known for its punch, versatility, and the explosive sound it delivered on countless rock, dance, and hip-hop hits since the 80s.
Although it can be used as a straightforward compressor, limiter, or de-esser, the unit really excels when the processes are combined, and when used to selectively process individual parts of the audio band. The possibilities range from low-frequency expansion and narrow-band compression, to general dynamic equalization, or creating surprising enhancement effects.
Five features not found on the original have been added to the plug-in. These include an MS matrix to separately process the mid and the sides, a mix control to balance the processed and unprocessed signal, a noise control to add or remove the modeled noise of the original unit, a gain reduction control, and an option for separate L/R metering.
