Its been an exhausting week, I'm busy trying to build a DSP processing pipeline on the STMF4 discovery board, however I'm failing to grasp a few things,maybe, I'm misunderstanding a few things. 
Here is a what I'm trying to achieve. 

1) Sample using the 12-bit ADC (this works)
2) Take the ADC sampled data and perform signal processing on the data. (this works)

3) Route the processed audio sample data blocks directly to the CS43L22, I'm not sure, if I can use I2S from the ADC???
or if possible, how do the STM ADC directly interface with the CS43L22 DAC.

Im seriously stuck at this point
