I am working on a music player for the iPhone, and I would like to crossfade between songs. I know this is possible because My DJ does it...I can't find any documentation and don't even know where to begin on it. Can anyone give me a starting point or example code?
Thanks.
One option is to convert both songs into raw (linear PCM) samples. Then build your own mixer function or audio unit where the mix ratio of each sample comes from a ramp or custom mix curve function. Feed the output to the RemoteIO audio unit.
I was able to solve it by using AVPlayer instead of MPMusicPlayerController.
