Don't give up, it may take a bit of practice to learn how to do it, well worth the time.

**I do recommend that you start out at first using very good audio examples, though, rather than attempting to grab audio from video files, etc. as those files are typically not of good audio quality. To learn faster, you might try Ripping files from commercial CDs, which are typically going to be good audio examples. And keep your endeavors to the simpler musics as well, which are not as daunting in the way of chord identification, etc.**
