Sugar Bytes Wow, €79
Sugar Bytes' appropriately named Wow will leave you saying exactly that. A combination of traditional filtering with the addition of formant filtering (which is used to create vocal-like vowel sounds), this little red devil is a real knockout.

TAL-Filter II, Free
Togu Audio Line has made it a mission to provide professional-quality effects for musicians on a tight budget. TAL-Filter looks deceptively simple, but the reserved GUI hides a highly flexible multimode filter with overdrive, dynamic panning and more. It's all designed to sync up with the host DAW's tempo, making it a cinch to whip up rhythmic modulations.

XILS-Lab XILS 3, €220
Do it the old-school way! Many vintage synthesizer emulations can be opened as effects plug-ins, allowing you to route your tracks through their filter sections. XILS 3 was inspired by the EMS VCS3, just like the one Brian Eno used to process his bandmates' instruments in Roxy Music.
