Hello, I have experience with editing, mixing and mastering programs, DAWs like: Protools, Audition and FL Studio. My work is guaranteed
The time spent also depends on the number of tracks and how well they are recorded or edited and how much work the mixing will take. Thus, to get a firm estimate, we need to hear your tracks and the shape they are in. But roughly speaking, it takes about 4-8 hours (average 6) to mix the first song for an “average song” with an average number of tracks (16-32 tracks).
