Does what it is supposed to. Completed my strange workaround well.
I Needed a way to get analog 5.1 into a receiver that has no analog inputs so I could listen to my SACDs.
So I needed some A/D converters (and they need to share the same sync). That gave me 3 AES/SPDIF signals.
Originally I Panned on using a DTS encoder. The beauty of that is simplicity, but no luck (not sure if the one I got was bad, or if there was some incompatibility). SO I went the Dolby Digital Route.
The only down side to the Dolby approach is complexity. My research indicated that non of the presets was truly appropriate given that the music has been completed and mastered. No need to do any processing. So I had to do some research on settings, but got it working without too much trouble.
A nice surprise is that it lets me run 680kbps for a 5.1 48/24 stream, which is unusual. But the decoder accepted it.
Does what needed.
