did you get the data from audio codec and save in a memory ? i'm trying to take the right data and the left data from audio core to a dual port ram . how can I use two channel or ıf you use Microphone how can arrange the parameters in controller code? can u send me your code for examine ?  about your question   ın wm8731 datasheet there is some information about volume control and db calculatıon   and in the cornell university final projects you can find the speech recognation project

I'm also working on a speech recognition project. Does anyone know of a temp program in VHDL coding that can show me an example of getting the input voice (one word) from a Mic on a FPGA Altera D2E board?
