That is if you browse music folder only. Browsing artist/album/genre/artwork
will be a combined result from all drives that are linked in.

So fraunhofer has announced MP3 Surround:

http://www.iis.fraunhofer.de/amm/download/mp3surround/index.html

As a person with a squeezebox attached to a home theater system, I
thought I'd ask again:

* Any chance for DTS and AC3 file support within Squeezebox soon?

and now...

* Any thoughts about other multichannel formats, such as MP3 Surround?

Just askin'... :-)

Right now, big priority is on stomping bugs in 5.4.1 without adding features
(more bugs) and then on SQL backend for 6.x, plus Unicode support and speeding
up both as much as possible.

DTS and AC3 might require a firmware change, and then its a question of if the
cpu is up to the task of dealing with 6 channels, which I wouldn't be able to
answer.

Do you have access to a GPL'd decoder for OSX, Linux and windows that takes
STDIN and spits to STDOUT?

Just askin' back ;)

Seriously though, that would be the easy way to go...at least as far as
converting to two-channel PCB playback or regular MP3. Playing native is a
whole other bag and probably well outside the scope of squeezebox. However,
I've been wrong before.

As for personal opinion, the SQL stuff has been a needed change for some time
now, and it is only now being tackled full on. Adding new formats is nice when
its easy, but chasing every new standard that comes out, i fear, would hinder
most chances for doing anything else. This, of course, assumes a steady flow
of resources, which is to say in a slightly different form: Patches Welcome!

I don't see how anything needs to be "dealt with" -- cending a DTS or
AC3 stream via optical should not require any interference on the
Slim side. It's just a matter of passing the data stream and letting
the decoder decode.

This ain't the dev list. ;)

Actually, I am skeptical about the Fraunhofer stuff, because it WOULD
require reprocessing. But passing an AC3 stream unhindered should be
easy, I'd think. Sean may correct me, because I recall him once
telling me that it would require a firmware update. Like a PCM
stream, AC3 and DTS don't need to be touched -- just passed, like a
(best case) bad chinese dinner or (worst case) kidney stone. (sorry
about that.)

Not quite. When an AC3 stream is sent via AES/SPDIF, it neads to be blocked
and packed, and a header added, and the blocks need to be sent at precise
(1536 sample) intervals. As I just completed an interface for transporting
AC3 streams over E1 yesterday, so I know a bit about it. Not difficult, but
a bit more work than 'just passing' the AC3 stream (at least the Squeezebox
will have to do some work, you could just stream the file to the
Squeezebox).

Thanks for the info-- and that definitely jibes with what Sean said
about it requiring a firmware update.
