Topic: 192kHz SPDIF / DD+
I'm looking for an audio interface that supports 192kHz over SPDIF
The DigiFace USB looks like it might do this, but the wording could be interpreted as if all 4 SPDIF outputs would need to be used simultaneously to achieve this:
Therefore at 192 kHz either 8 channels via 4 x SPDIF or ADAT are possible on both inputs and outputs.
The use case is packing Dolby Digital Plus into a 192kHz PCM wav file, which includes IEC preamble bytes, then playing out to a test device that supports DD+ over ARC. Getting ARC rigged up is outside the scope for this discussion.
Thanks in advance for any insights!
