AudioThing describes The Orb as a formant filter plugin which simulates the characteristics of the human voice. They say that, featuring a set of three band pass filters, The Orb can transform any sound into a vowel-like formant-filtered sound.
A spokesperson told us, "With the three LFOs you can modulate the Vowel, the Emphasis/Resonance of the formants, and the Drift, which can shift up or down the frequencies of each formant. You can also create your own set of vowels by changing name and frequency for each vowel/formant."
