Unique EQ with an exceedingly smooth sound and extremely useful features. 1. linear phase. Use it for transparent mastering applications. 2. super-useful spectrum visualizer built in. I sometimes use it just for this even if not using it to EQ. 3. innovative "spline" node methodology with near-infinite fine-tuneability for ridiculously precise sculpting while maintaining a natural sound. 4. Very nifty shift EQ curve by frequency and curve percentage (including down to negative) options. 5. pricing.... much more affordable than many more expensive but not as practical EQs. 6. it even has a built-in limiter which is quite good for curtailing occasional erratic peaks. 7. equally adept with smooth, gradual, shelf-like boosts or cuts as it is with tiny surgical work. The "spline" nature means that ideal smoothness occurs with every slope without having to stress out about what the perfect "Q" setting is for each band.
Cons? uses a good bit of CPU and latency if you want precise low-frequency sculpting. "Undo" doesn't work to undo steps, so set your settings carefully and back up your project because if you accidentally dislodge an established node, you'll have to remember where it was and re-set it manually..
Such a transparent equalizer (even more transparent than FabFilter's Pro-Q, which is obviously saying something). Great for placing on the master bus for shaping the mix (and doing extremely steep cuts - e.g. below 20-30hz).
