applies time stretching to audio by the specified factor r.

Details and OptionsDetails and Options

  • AudioTimeStretch stretches the input audio signal to the specified duration while preserving the pitch.
  • The factor r can be any of the following:
  • amountthe duration will be multiplied by amount
    Scaled[dur]a fraction f of the duration of the input audio
    Quantity[dur,unit]specifies the duration in the given time unit
  • AudioTimeStretch 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.
