http://stackoverflow.com – I've recently begun trying to create a mobile app (iOS/Android) that will automatically beat match (http://en.wikipedia.org/wiki/Beatmatching) two songs. I know that this exists out there, and there have been others who have had some success, but I'm running into issues related to the accuracy of the players. Specifically, I run into "sync" issues where the "beats" don't line up. The various methods used to date are: -Calculate the BPM in advance, identify a "beat" (using something like sonicapi.com), and trying to line up appropriately, and begin a mix in with its playback rate adjusted ( (HowTos)
