Hey hey everyone, sorry for cross posting. I released a set of three Csound User Defined Opcodes today. A pitch correction (autotune style), a channel vocoder (using an FFT-based technique) and a free pitching module, that pitches a voice - whichever pitch it has - to the MIDI notes received. All opcodes tested with Csound version 6.05, but should work on version 6.0. https://freeshell.de/~silvain/cs_voice_processing-0.5.tar.bz2 I've tested them live on a 3 gHz CPU running a Linux commandline. With a hardware sample buffer (-B option) of ifftsize they work in realtime. Any feedback and improvements are welcome! Thank you.
