Real time audio processing using Cirrus Logic Audio Card

[rmstark]

I am working on a project where I would like to take audio in from the line in jack on a Cirrus Logic Audio Card, perform some processing on that audio using C, and then pass the audio out through the line out jack.

I have been able to go record form the line in and then play back through line out so far, but only using the default commands. I have been trying to understand the WM5102 pdf but it's been a bit rough. Could anybody help me figure out how to access the audio data with C in real time or direct me to where in the documentation I could learn such information. I'm not sure which interface I should use. I was thinking I2C but am unfamiliar with how to use it or if that is right.

Thanks for any help.

Possibly the best source of information all in one place is http://www.element14.com/community/comm ... wolfson_pi but I don't know if that will answer your questions specifically.

Yeah, I've looked around there for a quite a while. There is a 300 page manual, but since I'm new to this I was hoping that someone who has done something similar could help me out rather than having to figure out which of the 1000s of registers I have to change on my own.
