8TT

8TT was one of my favorite free plugin releases of 2025. Where most OTT plugins give you three bands, 8TT lets you work with up to eight. You can also scale it down to a single band or split the spectrum into as many as eight independent compression zones, which gives you far more precision over how the effect shapes your sound. The interface is built around a drag-and-draw system. You can double-click to split a band, drag horizontally to adjust crossover points, and draw compression amounts directly on the display.

It’s pretty intuitive once you get the hang of it, even though the minimalist design initially caught me a bit off guard. 8TT also includes sidechain input, oversampling up to 8x, an output limiter, a fun little randomizer for creative experimentation, and a preset library with starting points for drums, synths, and vocals. That’s quite a lot for a free plugin. I typically reach for 8TT when I need more surgical control than a standard three-band OTT can provide.

It delivers a smoother sound than what I was previously getting from other OTT-style plugins.
