Multiplexed 12 bit audio

Question asked by AnthonyCSmith on Jul 14, 2017
Latest reply on Aug 9, 2017 by AnthonyCSmith

I have an application where the ADAU1701/2 would be ideal, but the lack of bit shift will be a problem, I have 2 input streams with each stream being audio packed as four 12 bit numbers (2x 12bit left and 2x 12bit right) I need to de-multiplex these and re-multiplex them as 2 x outputs streams.

I am wondering if there is any way of preserving the sign bit from the lower 12 bits?

Any help would be appreciated
