Explanation: Nowadays, CDs have mostly gone the way of cassettes. Still, make sure you have a hardcopy high quality audio recording. DVD audio is best, as is (still) CD. MP3 is great for distribution to the consumer, but not for you. It compresses the music and you will lose a lot of the richness. You may consider saving it in WAV and then burning it to a disk (CD or DVD is best, because they are safer) so you will have a high-resolution audio copy.
When you finish, your file will be in WAV format, most likely. You can export to MP3 for YouTube and online digital distribution easily, from most all programs. Try Audacity (Google it and download this great free software).
