1. Make sure you send the highest resolution possible.
2. Don't over EQ when mixing - better to be a bit dull & let your mastering engineer brighten things up.
3. Don't over compress when mixing - In general it's best to compress and control levels on an individual track basis & not on the stereo buss.
4. Getting levels between songs to match is not important - Just focus on getting your mixes sounding great & let your mastering engineer take care of this for you.
5. Getting hot levels is not important - in fact it's best for your mastering engineer to leave 3-6 db headroom or more.
6. Watch your fades - If you trim the heads & tails of your track too tightly, you might discover that you've trimmed a reverb tail or an essential attack or breath.
7. Document everything - Document flaws, digital errors, distortion, bad edits, fades, make sure every song is properly ID'd ...
8. Check your phase when mixing
9. Have your songs timed out - Most CD's have a time of 78.33 minutes
10. Leave two seconds of recorded, unprocessed silence at the beginning & end of your tracks. This gives me room to make a noise profile so I can get rid of all the unwanted background noise. This is especially important for record recording clean ups.
