When I used to have a studio for hire, we'd often track 8 songs in a 10 hour day. The band would leave with rough mixes to take home. The next day we would go over it, retrack if needed and then mix. So, 2 to 3 days.
but.......I had a secret weapon, I'll post later.
My secret weapon was that I owned a rehearsal studio. I'd have the band rehearse for a couple of days and would pop into their room from time to time and see how it was going. We'd go over production, arranging, etc. This would get me familiar with the band in all aspects from skill to personality as well as the songs.
When I felt they were confident and ready, we'd go upstairs, set up mics, and once again rehearse. But this time it was with them set up for recording. I wanted them real comfortable playing under the microscope, and totally comfortable in the studio environment. Often rehearsals were done with cans. Sometimes if the band was doing some magic, I'd hit record with them unaware.
For a 4 piece Rock and Roll band, this method worked real well, and 1st and second takes of a tune were often keepers.
Then again, I'd done whole albums with bands that took anywhere from 2 weeks in the studio to a couple of months.
So there are many variables, but probably the most important factor is this. How ready are you and your band?? A studio on the clock is NOT the place to work out arrangements, songs, and production ideas........Unless you got pockets full of money.
There is no absolute formula for how long it will take. It is best to expect that it will always take longer and cost more than you had planned for.
