I recorded this scene and edited it with Audacity. This is the scene in which Macbeth is shown parade of eight kings by the witches. I added a screaming noise at the end that can be interpreted as the screams of ghosts, the witches or even Macbeth's conscience. I also added an echo to emphasize the hallucinatory nature of the scene. The music seemed foreboding, droning and Celtic, all perfect for the background.
