Time Stretch/ Pitch Mod Using FFT


    Mar 26 2013 | 3:15 pm
    Hi
    For a uni project I am building a time/pitch manipulation patch using the pfft~ object
    I have been using the tutorial patch on phase vocoder to get me started with various articles online to help me tweak this however i feel i am not really doing anything different from the tutorial patch. I was wondering if many other users have experimented with this type of DSP and have any patches i could browse/take apart to help with mine or just some ideas of things to experiment with. I grasp the concept and how this is executed in the example patch but at my level i cannot see how to improve on it. i have added different pfft~ objects with different windowing types but i have become some what stuck on how to further this.
    Ways to create smoother/rougher synthesis?
    I promise not to steal your patch - i have integrity. also my tutor is a user of max so he WILL find out - he will probably read/reply to this thread.
    I just need some inspiration or advice.
    Any help will be gratefully appriciated.
    Please ask any questions if i have missed anything your interested in or what not
    Thanks Again
    Lloyd

      i guess nobody has anything on this?

      For what it's worth, I've found Christoph Charles' jitter-based phase vocoders to have a lot more room in them for tweaking, but that may not be in the official purview of your project...

      for your needs this is the best url in the universe:
      if you've got a spectral processing idea for max-- it's most likely already been done by JFC
