The Post Production Tune-up is when you just want to make minor adjustment to levels, change your track sequence or spacing, smooth fade-outs, and clean-up noise between songs. This is not a full mastering session, and typically does not include EQ or compression. One flat rate covers your whole album.
For more in-depth adjustments to your project, including custom EQ and level adjustments to each song, or if you need the overall level raised significantly on your mixes, a full mastering session at $59 per track would be more appropriate.
Note: Mastering will add 3-5 days to the overall turn time of your project. You will receive an audio proof to approve.
