How loud should mix be before mastering?
To get great mastering results, it’s important to correctly set your mixing levels. As long as your mixes give the mastering engineer room to work and cover your noise floor, then you’re in a good range. I recommend mixing at -23 dB LUFS, or having your peaks be between -18dB and -3dB. These are however general guidelines. In the end, all mastering engineers adapt the level to their chain anyway.
