For a home project (like I have time for it) I'm implementing a
virtual preamp: TV, Mac, AppleTV, DVD, etc. in --> decoding / efx
processing --> multi-channel out. Things are working pretty smoothly
but I've got a pile of USB SPDIF interfaces hooked up to a Mac mini
which is, shall we say, not very aesthetically pleasing.
Is there any input device out there that has multiple *independent*
SPDIF interfaces on it? When I say independent, I mean that they are
all individually clocked and don't try to do any fancy tricks to make
the audio bits all line up. As you might expect, for the most part I
am trying to receive digital bitstreams, not PCM, so any clock
stretching tricks will totally destroy the data.
To be honest, I'm not sure it is even possible for a device driver to
present multiple streams running at different sample rates/clocks so
I'm guessing the driver would have to export multiple AudioDevices.
That seems unusual for a product idea but it'd be sweet if I were able
to consolidate all of my inputs into one box. Has anyone out there
seen such a beast?
If not, any hardware folks out there who have a recommendation for the
SPDIF receiver chip-of-the-day? It's been a long time since I've done
any hardware but it'd be nice to have the info for reference in case I
ever need it. :-)
thanks,
stephen
