Technical question regarding music streaming in SL

[Jaffee Gaffer]

I'm a long time DJ in both the real world and in SL and I understand pretty well how the process works. My question is this. Does Second Life pass the digital stream packets through to the viewer which converts the music to analog or does it somehow pass the analog audio stream? I'm guessing it passes the original packets to the viewer for conversion to analog audio. Can anyone answer this with certainty?

Thanks.

it's passthru,  your source is what they are listening too.
