Never underestimate the production power of filters!

Filters VideoWith EQ, we seem to work the parametric EQ the hardest.  Cuts and boosts throughout the audible spectrum let us remove the ugly parts and enhance the tasty bits.  But don’t neglect the creative possibilities that come from those too-often-neglected filters.  Perhaps the most mature use of filtering is not about spectrum, it’s about depth and distance.  A subtle amount of high frequency roll-off can perceptually shift sounds back, away from the listener, to positions behind the loudspeakers.  It’s a cool illusion, and an essential way to get your mixes into another dimension, quite literally.  Simple mixes leverage the left to right dimension.  Use filters to access the front to back, near to far dimension in your mixes.
