Expurgate is a fully-featured gate/expander, with all the customary DMGAudio trimmings.
Let's be honest - gates are not the most exciting of processors, but they are hugely useful. So I've tried to make Expurgate as exciting as possible by including a selection of favourite gate designs. We've tried to make it as quick to use as possible by streamlining the interface, and including a flexible sidechain EQ with spectrum analyser. I've made it as gentle on the CPU as possible whilst still sounding fantastic and also including extra options for more demanding applications to invoke more processing power.
The inclusion of a signal/noise detector can make some tasks, like breath gating, extremely quick to get good results with. Adding sub-band processing means you can use it for tonal and dynamic shaping. The sample-accurate MIDI handling is pretty neat for creative uses, as is the distortion characteristic of using extremely low attack and release times when the safety is off.
We're fairly sure this is the most sophisticated and flexible gate around. As we strive for in our designs, it allows you to get the job done quickly and well. And as always, if you want to go deeper, the options are all there.
