If you plan on having your music mastered professionally, it’s best to present them to mastering houses in the original files such as WAV, AIFF, and etc. (see previous tech tip), but if you are sending in a CD, here’s two quick tips:
Tip 1: Keep any paper labels off your master CD-Rs – they inhibit the rotational balance and can cause the player’s error correction to work harder.
Tip 2: Only write on the top of CDRs with a soft felt-tip pen (preferably alcohol-free) prior to burning the CDR, not after. The top is more fragile than the bottom!
