Constructors

Stretcher (Ptr Stretcher)

type SampleRate = Int

Samples per second of the input and output audio.

type NumChannels = Int

The number of channels processed by a stretcher.

type TimeRatio = Double

A ratio of stretched duration to unstretched (original) duration.

type PitchScale = Double

A ratio of output frequencies to input frequencies. For example, a ratio of 2 will increase the audio by one octave, and 0.5 will decrease it by one octave.
