I am a musician, and I do most of my own recordings. In fact I have helped many musicians record smal projects they have been working on. I feel comfortable recording and doing a little mixing. I want to put together a full album, I want to do be it's best, so I have decided that I will send it to a mastering engineer to put it all together. My question is what does the mastering engineer need from me? Sure, the audio files, but what format is preferred? Also, is there anything in the recording process (beyond the usual things) that I should be aware of that might help the mastering engineer? How much mixing should I do? by that I guess I'm asking if I mix the project to where I like it then send it to the Engineer? Do I mess with eqs, or do I send it raw? As you can probably guess I am new to the mastering side of things, so even if you could point me to a place with more information that would be appreciated. I am probably going to record using Cubase or Logic, and I have access to good equipment. My music is mostly acoustic with vocals.
