I was looking some freeware formant filter, and seems like they lie under rocks. (Means hard to find/are rare ) One I could find, it was called just format filter (no caps there on the name), can’t remember the author, Oli something. It has five formants and couple of vowel presets and syncable formant mod LFO. It’s decent, but I have room for better. I know there’s this VoxFX or something like that which is really hi-fi but it isn’t free and I’m after maybe something simpler. Know any good?
