my band is researching some potential mixing engineers to hire to mix each of our 2 cds. each has ~70 minutes worth of music on them. approx. how many 12 hour days should we budget for to mix that much music? the songs are fairly long, if that makes a difference - the first cd has 8 songs and the second has 9. the arrangements are multiple guitars, bass, drums and background synth, with single and multiple harmony vocals (up to 14 tracks in some places) and many long instrumental sections. assume in your time estimate that all the potential preparations - format conversion, noise cleanup, notes and track listings are all completed. furthermore, each guitar track has the desired effects and is already mixed to a stereo pair, as is the bass (mixed and compressed where necessary). the only tracks that universally are uneffected and in need of outboard attention are the drums and vocals. we have a pretty good budget to mix each cd ($10,000 to $12,000), so hopefully we can consider a wide range of options. your help is greatly appreciated.
