Just wondering what is the best way to process audio so I can output what note is being read in. I am doing a guitar tuner for a college assignment and I am new to Android development. I have seen the Android example on recording sounds on from the Google API, but I was wondering where to go from there? I understand I have to do a Furior Transform or something to get the frequency, just wondering if anybody has any advice on how to do this. Once we can get the correct frequency displayed on screen we have a bulk of our project done. Thanks for any help.
