One of the most crucial mix phases is referencing the tracks outside of your studio and getting feedback. One way to help remove the obvious distraction of your mix being at such a lower volume than a typical commercial release is to strap a limiter on the master fader just before you bounce down your mix.
Getting You In The Ball Park
The goal of this move isn’t to call that a mastered track, but rather to get the volume of your mix in the ball park of that of a mastered CD. This keeps the client (or yourself) from being distracted by your mixes low volume, and instead allows feedback to be drawn from how the mic actually sounds and compares to other mixes.
