Apart from what has been said above, the aim of album mastering is to make individual tracks sound coherent and work as one-peace product. This means the music will flow naturally, avoiding any disturbance when song changes from one to another, the levels in all songs will fit just right avoiding the need to use any sound controls while listening to an album.
Individual songs can be mixed within 3-4 days. (We reserve 7 days to be secured). Mixing of album will take longer, as it requires a lot of adjustments of different sound variables in each song that it rather time consuming by itself, however it varies from track to track.
