I'll describe Autotune as a pitch "discretiser", though I've been unsuccessful in my attempt to recreate a similar effect.
I want to create a bitstream effect from a water stream recording and I feel like it's the effect I need. First I tried Digi's Lo-Fi but this produces an old-sounding modem-like effect. I've played around with compressors and expanders to make an aliased (square) envelope but I can't find anything for the pitch.
Have you ever created a bitstream sound effect this way? I think I read about this on this board but can't seem to find it... About the DIY Autotune, do you know of any trick to get it done?
