DMGAudio Compassion

DMG Audio has released Compassion, a fully-featured dynamics plug-in that promises to be ready for any processing on any signal. Not just a compressor, Compassion can handle gating, sidechain, parallel compression, frequency-conscious and frequency-specific compression (dynamic EQ style), overcompression, the ability to SHAPE your attack/release curves, a transient shaper, a hybrid clip-limiter module, and much more.

As developer Dave Gamble discovered, “Each different compression task will have a unit best suited to it. So it seemed natural to develop a model of dynamic processing that included all the different schools of design, and build a unit that would allow you to get the job done, no matter what you needed to achieve. I came up with an idea that fused measurement with circuit design. I measured different compressors, built models of the circuits and then unified all the models into one gigantic structure that could model any of them. Then I made as much of it variable as possible; so you could dial in designs in between models.”
