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.
I am not going to take credit for this one, because I read it in an interview with Tchad Blake.
In Pro Tools duplicate your kick drum track, insert the San Amp plug-in and adjust until you get a thick round low end with some distortion. Now include your clean source track and REVERSE THE PHASE on your Sans Amp track. Continue adjusting Sans Amp Plug-in (especially buzz and low knobs and take down highs) until you hear it sound like it is an octave below. I was skeptical, but works great for a thick kick.
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.
When tracking drums I always have trouble with hearing drummer talk, so I set up a talk back mic for him to communicate to me from drum room to control room. The problem exists when I start tracking the song, the talk back mic is also picking up the drums. Yuck, annoying! What to do? Here is the trick; I put a 1k tone on an Audio Track and create an Aux Track with the input of talk back mic. I insert a compressor on Aux track and set it hard. I then side chain that 1k tone into the compressor. Voila! When I initiate play on DAW talk back mic cuts.
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
