Ok. First off, here's my set up. My DJ and myself and a few other musicians have recorded about 10 tracks. I recorded them using a Motu 8Pre and Ableton Live 8. I want to clean up all my tracks with a consistency so they all sound related. I know that an album can benefit greatly from mastering, so this is something that I'm willing to spend money on so it can be done professionally. So what exactly falls in the realm of what's called 'mastering'? Will they set the individual tracks in the song so they the sit better in the mix? Do they only work with the master track and adjust things so there's a consist volume/compression level? I'm just unsure of what to expect, and how to prep my files for the handover. Also what's a reasonable price to pay for mastering? Thanks in advance guys.
