AudioEffectPitchShift
=====================

**Inherits:** :ref:`AudioEffect<class_AudioEffect>` **<** :ref:`Resource<class_Resource>` **<** :ref:`Reference<class_Reference>` **<** :ref:`Object<class_Object>`

Adds a pitch-shifting audio effect to an Audio bus.

Raises or lowers the pitch of original sound.

Description
-----------

Allows modulation of pitch independently of tempo. All frequencies can be increased/decreased with minimal effect on transients.
