I'm having some trouble figuring out how to crossfade audio with events, crossfading is a process where as one audio file fades out another one fades in. I need to be able to control the length of the crossfade, and if possible the 'type' of crossfade too. It's quite a core audio feature that many people will find useful.
Here's an image to demonstrate:
