Pitch detection using verilog HDL codes

Hi, I would like to do some pitch detection using verilog codes. Does anyone have done it before? Firstly, I would like to save my recorded audio files (.wav files) into SDRAM on DE2 FPGA...

I'm working on an audio processing project now using the DE2. I'm pretty much a VHDL, fpga and Quartus beginner. It is straight forward to do but in practice i've spent hours and hours messing around with stuff. Today i got the audio samples in and out of the SDRAM with control over the read pointer for delays etc.

So yeah, i'd say its doable. Start with getting the CODEC audio samples in and out of the FPGA.

These forums are great for help! i'd be stuck without this.

Good luck and sorry if this isn't much help
