PSP BussPressor: Bus and Master Compressor Plugin by PSP Audioware

BussPressor is designed for group and master bus duties, where a compressor needs to glue several elements together without drawing attention to itself. The plugin is built around the sound of classic VCA compression, a style many producers associate with mix bus cohesion.

Wide tuning capabilities let you adjust how the compressor reacts across different kinds of material, from drum groups to full stereo mixes. Because the design is aimed at the bus, it suits settings where you want gentle, musical control rather than heavy, obvious squashing.

Two extra controls set BussPressor apart from a basic bus compressor. The sidechain high-pass filter lets you keep low frequencies, such as kick and bass energy, from triggering the compression, so the rest of the mix can breathe when the low end is loud.

Parallel compression lets you blend the compressed signal with the dry signal. This is useful when you want the density of heavy compression on a group while keeping the transients and dynamics of the unprocessed sound underneath.
