Hi!

For an upcoming project, I need to read several I2S slaves. It would be 
great to have a hardware solution that does not require programming.
So, does anybody know an Interface card or USB device, that would allow 
me to read 6-8 I2S slaves with 32 bit at 48kHz in parallel?

Many thanks,

Axel

These are the two solutions I know of:
* XMOS (software implementation, open source, 2-40 channels): 
http://www.xmos.com/products/reference-designs/multichannel
* RigiSystems (32 channels):

Great!

Many thanks, the RigiSystems USBPal device may be a solution. I am not 
sure if 32 bit I2S is supported, but I will ask them.

The XMOS sees to have only analog audio connections.

I also found one by MiniDsp but this does have only 8 channels and no 
documentation:

This is just the eval board, there are other boards based on the XMOS 
reference design, e.g., MiniDSP.

There is a link to the user manual right on the page.
