I was interviewed on the radio and recorded it via the speaker on my computer. Obviously, the quality is hollow and not at all crisp. I have Audition and want to correct this so that the recording has a sharper sound. Admittedly, I only have very rudimentary skills on Audition. Until I learn how to do this myself, can someone please provide me with a step-by-step solution?
Secondly, so that I can improve, what's the best available video tutorial?
