Plugin Boutique has launched a sale on three filter effect plugins by Kilohearts.

The Comb Filter hollows out the sound by carving out frequencies at each multiple of the base frequency, like the teeth of a comb. It’s also possible to process left and right differently in a way that not only gives a wide stereo effect, but also collapses right back to the original signal when mixed to mono. Nifty!

kHs Filter is a resonant filter with 7 modes, swiftly getting rid of frequencies you don’t like or enhancing frequencies you do. And it’s doing it and doing it and doing it good.

The Formant Filter offers vocal coloring. If your music doesn’t get enough “Aahs” and “Oohs”, maybe you should try putting them into the actual music? Formant filter shapes the sound in a similar way to how the vocal tract works, leading to vowel-esque sounds. So, channel your inner robo-Tarzan. Aaaaoooeoeeeoeeeee!

The plugins are available for Windows and Mac (VST/AU/AAX/Snapin), and on sale from Plugin Boutique at up to 52% off until March 6th, 2018.
