Pitch - Shifting

  • SoundTouch Audio Processing - the main file for audacity's pitch-shifting functionalities.

    • pitch-shifting is done by using a combination of rate-change and tempo-change. I think "anti-aliasing" tries to smooth over the resulting choppiness of tempo changes. Tempo change method is simple granular synthesis type technique.
  • AudioFFT by robersiegel - implementation of pitch shifting using fast fourier transforms.

    • Use Hanning Windows to create grains
    • doesn't run at all, its essentially pseudocode :)
    • todo: try to make it run :))
  • same thing implemented in C and an explanation of STFT (short time fourier transform

    • step 1: cut sample into grains s.t. grains are relatively stationary.
    • ???
    • measure "partial frequencies" of grains. ( I believe this is the decomposition / finite fourier series)
    • scale the frequencies (these are sine waves so you are just generating new size wave at relative different frequency and relative position to other frequencies)
    • "We also see why pitch shifting using this procedure automatically includes anti-aliasing: we simply do not compute bins that are above our Nyquist frequency by stopping at fftFrameSize2. This does not even need an additional processing step."
