USB sound card to receive 192k/24 bit digital audio Topic is solved

[tuck1s]

Just came across this wonderful site!  Looking for some basic guidance.

I'm trying to receive and store an audio stream running at 192k / 24 bit.  It's actually got 8 channels @48k interleaved, but I should be able to sort those out offline in batch mode once the data stream is stored.

I have a Wolfson WM8804 S/PDIF receiver producing I2S data, BCLK, LRCLK.  The basic bit rate is 12.2Mbps, and my Raspberry Pi is not co-operating (the drivers for I2S input are apparently not available).

Would it be possible to use an XMOS device to process this incoming stream and present it via USB, using standard sound-card drivers to a more powerful PC (e.g. running Linux or Windows)?

If so, are there readymade boards I can use?

Yes an XMOS device could be used to do that - a suitable platform would probably be the U16 slice kit with Audio 8 slice which is available soon.
