I heard from somewhere that the PS4 uses a custom Sony audio format. Is this true, what format is it and are there any tools out there for working with it?
Yeh I already read up a bit more on this the morning after my post but didn't bother adding it here. It's also used on the Vita. And some SDK (PS4 one I think) was leaked some time ago that also has a tool to deal with this format, to at least convert to at9, not sure about the other direction. So if you wanna play with these files there you go.
