Has anyone tried to make an autotune emulation using ChucK? Seems like it would be doable, albeit with constraints. -- Philipp Blume
Autotune requires a pretty accurate pitch-tracker, which isn't built in to ChucK but is available as part of my Chugin package at https://github.com/jwmatthys/chugins With either the PitchTrack or Sigmund chugins, you can do autotuning like this in ChucK: https://soundcloud.com/jwmatthys/obama-autotuned-chuck-version https://soundcloud.com/jwmatthys/obama-resynthesized (Sample code is included with the chugins.)

Oh, hey Joel!
Sigmund is wrapped in LiCK as well

Sweet! I gotta keep up with all of your amazing work, Michael! BTW, have you looked at wrapping the bitrot Ladspa plugins? They do some great glitch stuff.

Hello Joel,
No, I haven't yet, those look awesome!
The main point of my plugin wrapping is to make them an instance of
Effect, which provides wet/dry mix and stop/start functionality as if
the plugin were a guitar effect pedal.

Hello Philipp,
If you're willing to use LADSPA via the ChucK Chugins mechanism, then yes
https://github.com/jwmatthys/chugins/blob/master/PitchTrack/autotune-test.ck
Joel's PitchTrack and RubberBand
(http://breakfastquay.com/rubberband/) are also wrapped in LiCK
