Well... There are a few places where you can get much of davening, and there are many places where you can get some of davening, but there is no place where you can get all of davening. I'm trying to create such a place. I will not succeed, but hopefully over time there will be a solid collection of resources. For now, though, I would recommend Offtonic Nusach Resources. Browse the sites there; they are categorized generally by service and ranked within that service based on the quality and quantity of their offerings. They include resources from around the world, though mostly only in languages that I can sorta understand! I am also creating NusachDB, which categorizes different melodies for each section of each service, but I haven't gotten very far yet; the wedding service, at least, has quite a few different melodies.
