This sketch demonstrates how to use the isEffected method of an Effectable class. The class used here is AudioPlayer, but you can use this method on AudioInput, AudioOutput, and AudioSample objects. This sketch adds a low pass filter to the player. You can enable the filter by pressing 'e' and disable it by pressing 'd'. The text on the screen will inform you if the player is effected or not (and so will your ears).
