Assuming that desired services were properly booked and scheduled, tracking of 1 song track by track can be done in 1 day (8-10 hours). When tracking all instruments at once (+ vocals overdubs) then 3-4 songs can be done in 1 day if the band is well prepared. It all depends on the count of instruments, the genre of the music and how well is the band prepared. Album-tracking can take 1 - 2 weeks. Mixing and mastering of 1 song can be done in a couple of days, but it depends on how fast can the band communicate during revisions. Mixing and mastering full-length album may take up to 4-6 weeks. Mastering only of an album can be done in 3-5 days. When producing, the whole album making can take from months to years depending on many factors and the style of cooperation.
