Im doing speech stenography which is implemented in Xilinx Zynq board. Im new to this board and currently Im learning the basic configuration for this board. As my project will apply two voice signals as host signal and secret message, I need to convert both of them to become digital based signal. Is anybody has experience to use ADC or codec in the board before use it for stenography process or other purposes. FYI, speech stenography is new explored by researcher compared with other type such as image stenography. Presently, the design of the system is successfully simulated using Matlab and Modelsim. It was designed by PhD candidate from UPC Barcelona. Now im doing post doc to continue her work. My task is to implement the HDL code on Xilinx Board.
