SideBand Remix is an AUv3 plugin for final mixing and mastering. It separates the phantom center from sideband (L/R) content which is what give a stereo track its width, and lets you remix it. This is ideal for adjusting the level of centrally panned vocals without affecting everything else. SideBand Remix is great for post-production engineers who want to reposition, isolate, and even eliminate elements of their mix. Audio can be additionally split into 3 channels, LOW, MID and HIGH frequency bands which are all processed separately and eventually re-combined after processing. This allows you to control the bass and treble portions of your mix separately from the mids where the vocals naturally sit. Being able to push content from the center of the mix opens up room for a vocal to sit comfortably. The punch knob can be used to boost low and high band content or presence, while the shelf filter are there to make sure they never get out of control. As if that wasn't enough you can enable the harmonic exciter to inject top end sparkle into the mix or enhance low end frequencies. This is a versatile little tool that can be used on drums as well as vocals. Remove reverb from those snares and give your drum beat that punch it deserves.
