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...

Hi, Tap.

Thanks for your advice and guidance. :)

May I know how did you get your audio samples in and out from the SDRAM with control of the read pointer?

Is your audio samples in (.wav format)?

Where did your audio samples inputted?

Is it thru the line-in / microphone?

"Start with getting the CODEC audio samples in and out of the FPGA"

meaning I should store my audio samples in the audio codec but not the SDRAM first?

What if I store my (.wav audio file) in the SDRAM instead of the audio codec, will it be less complicated? provided my (.wav audio file) is less than 1Mbyte.

Thank You.:)
