� the current state of the art for pitch manipulation is, of course, Melodyne. dunno how Peter Neubacker does it. somewhere, i have some old MATLAB code that does a time-scaling via phase-vocoder.� you can combine that with resampling to get a pitch shifter. if it's pitch shifting a monophonic note, i would recommend a decent time-domain cross-fading method that has a decent pitch detector so that the splice displacements are good. a Laroche/Dolson did a real-time phase vocoder pitch shifter.� all doable but it's not a small project. ---------------------------- Original Message ---------------------------- Subject: [music-dsp] Real-time pitch shifting?
