applies pitch shifting to audio by the ratio r, shifting every frequency to .

Details and OptionsDetails and Options

  • AudioPitchShift shifts the pitch of the input audio signal without affecting the duration.
  • The frequency ratio r can be given as a pitch interval, including:
  • Quantity[oct,"octaves"]correspond to
    Quantity[sem,"semitones"]correspond to
  • AudioPitchShift takes a PartitionGranularity option that controls the partitioning of audio, used for the computation of the short-time Fourier transform.
  • By default, automatic partitioning is used to get a compromise between performance and quality.
  • A small window size will result in better processing of transients, while a larger window results in a higher-quality output.
