thr33some is a multi-band stereo tool, to allow you to widen or narrow specific frequencies in your mix. Typical use would be to make bass sounds mono whilst progressively spreading higher frequencies, but abuse and experimentation will yield some interesting effects too. Thr33some has 2 methods of stereo spread and with gain and pan per band you have total control over all 3 bands. You can also make each band full spectrum to get 3 full layers and control in and out gain with metering to keep levels under control. There is also a multi-out version for individual processing of each band in your DAW.
