    • set_waveform

      public void set_waveform(int waveform)
      Specified by:
      set_waveform in class Oscillator

    • set_waveform

      public void set_waveform(int harmonics, int waveform)

    • get_frequency

      public float get_frequency()
      Specified by:
      get_frequency in class Oscillator

    • set_frequency

      public void set_frequency(float frequency)
      Specified by:
      set_frequency in class Oscillator

    • set_frequency

      public void set_frequency(float frequency, int interpolation_duration_in_samples)
      alternative version of `set_frequency` which takes a second paramter that specifies the duration in samples from current to new value. this can prevent unwanted artifacts ( e.g when quickly changing values ). it can also be used to create glissando or portamento effects.
      Parameters:
      frequency - destination frequency
      interpolation_duration_in_samples - duration of interpolation in samples

    • set_offset

      public void set_offset(float offset)
      Specified by:
      set_offset in class Oscillator

      Specified by:
      get_amplitude in class Oscillator

    • set_amplitude

      public void set_amplitude(float amplitude)
      Specified by:
      set_amplitude in class Oscillator
      Parameters:
      amplitude - amplitude

    • set_amplitude

      public void set_amplitude(float amplitude, int interpolation_duration_in_samples)
      alternative version of `set_amplitude` which takes a second paramter that specifies the duration in samples from current to new value. this can prevents unwanted artifacts ( e.g crackling noise when changing amplitude quickly especially on smoother wave shape like sine waves ). it can also be used to create glissando or portamento effects.
      Parameters:
      amplitude - destination amplitude
      interpolation_duration_in_samples - duration of interpolation in samples
