`from PyKDE4.phonon import *`

Inherits: QObject,Phonon.MediaNode
Subclasses: Phonon.VolumeFaderEffect
Namespace: Phonon

## Detailed Description

\class Effect effect.h Phonon/Effect Effects that can be inserted into a Path. An effect is a special object which can perform transformations on the specified path. Examples may include simple modifiers such as fading or pitch shifting, or more complex mathematical transformations.

In order to use an effect, insert it into the path as follows:

     Path path = Phonon.createPath(...);
     Effect *effect = new Effect(this);
     path.insertEffect(effect);

The effect will immediately begin applying it's transformations on the path. To stop it, remove the Effect from the path.
