Earcandy is an application which is interpret using Pulseaudio. The app fade out music whenever you receive a Skype call or make one, also when you have music playing and then switch to a video.
Imagine, you are rocking to your favourite type of music and all of a sudden you receive a Skype call, (you quickly need to mute the music and awnser the call), while doing this you worry about the caller and when he might put down. In a hurry you ACCIDENTALLY turn the music LOUDER instead of softer. finally when the music is muted the caller already putted down.
Now imagine this! You are rocking to your type of music when suddenly the music fade out and you hear the Skype caller tone, you press answer :) and enjoy your call.
