This is a fairly common practice and a widely known trick. To excite a lifeless or dull vocal, you can duplicate the vocal on a new audio track and nudge it behind about 300-400 samples. Insert a low pass filter at 5k. Add a compressor at 10:1 or more , EXTREME! Stick a Desser at the end of chain to clean up. Mix that right behind your source vocal.
This is a problem solver when gating snares. Typically snare gets clipped at its front when gating, so here is the trick. Put a gate on your snare track and enable the sidechain. Duplicate your snare track to a new audio track, pull down volume all the way and move it slightly earlier with a pre send sent to sidechain on original snare track. Gate will now be triggered ahead which will rectify clipping problem.
What a great buy this console is. Great support and sounds absolutely wonderful and pure. I like a little character, so I combine the Audient with some Neve and API mic pre's with some of my fav compressors, like a Urei 1176LN or SSL FX 384. That's just enough salt & pepper to make my kind of record.
For 5.1 Surround Sound I use the Audient ASP510 controller
