Is this possible?

Posted by: EastEnder on 20 March 2015

The minimalism of this setup (controlled via iOS app) appeals to me:

SSD USB drive -> Raspberry Pi -> HiFiBerry Digi+ -> Naim nDAC (via coaxial)

My question is simple: is it possible?

Assuming it is possible - what software would be required on the Pi and iOS device?

Responses appreciated and thanks provided in advance.

Mulberry, useful reference, and indeed the TOSlink bandwidth can be critically set by the sender and receiver optical transceivers, with cheaper ones being limited to around 6Mbps.

One thing to note is that SPDIF is a framing protocol, and so there is overhead on top of the raw encapsulated PCM, as it is split up into groups of frames with their own headers. Therefore 96/24 is going to require more bandwidth than 4.6Mbps. The overhead ratios are on the web somewhere and has been defined as a ratio of transport clock to PCM sample clock.
