Re: [chuck-users] Auto tune

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. michael On Wed, Jun 11, 2014 at 11:58 AM, Joel Matthys wrote:

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. Here's something I did with them:

Oh, hey Joel!

Sigmund is wrapped in LiCK as well

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:

(Sample code is included with the chugins.)

Has anyone tried to make an autotune emulation using ChucK? Seems like it would be doable, albeit with constraints.
