Intonation parameters

This window controls how the intonation curve is generated.

Control group:

• Micro intonation:
  Intonation generated by Special Transitions. It produces fast and localized pitch perturbations, and may not have a small amplitude.
• Macro intonation:
  Intonation with a global effect, generated by a specific intonation code. The pitch variation is slower than the micro intonation.
• Smooth intonation:
  When enabled, the pitch between intonation points is calculated using cubic interpolation. When disabled, the interpolation is linear.
• Random intonation:
  When enabled, a set of intonation parameter values is chosen randomly. Each time a text is synthesized, the generated intonation may be different from previous executions.
• Intonation drift:
  The drift adds a fluctuation to the pitch.

Parameters group:
If the checkbox "Use these parameters" is checked, the intonation will be generated using these parameter values instead of the parameter values from the configuration files.

Drift parameters group:
These parameters control the drift generator. The deviation value is not necessarily the maximum amplitude, because the signal is filtered by a lowpass filter. In other words, it may be necessary to set a deviation value that is higher than the desired value.
