I have been programming for a year or so. Mostly the basic command line stuff. I want to learn more so I want to make a program that will convert mp3 to mb4. Where do i get stated. So far i have figured that finding a already written library is my best bet, but which one. Preferable on that has good user instructions because i am still fairly new.
SFML also has an audio library with some good documentation and not too many features (low level). It gives you the ability to access the raw audio data and manipulate that which would fulfil your requirements.
