I want to make a program that when i plug my guitar into the mic jack it can sense the frequency and print the chord that it is. I know there are open source projects that have the same thing buti want to try to learn how to do this myself. All help is appreciated.
You will need programming experience before tackling such an immense task, scottk is correct. Detecting the frequency and sound info is no straightforward task. Do you know how to program? If so, I may be able to offer some help.
