If you’re a producer then almost certainly you are being short changed by the acoustics in your room and your monitoring environment. Maybe you need to use headphones only. Maybe your speakers are cheap. Maybe you just have blocked ears because you spend too much time in the pool (like me). In fact I have all of these issues.
Voxengo Span is the best plugin I have found that really gives a clear picture to the levels on your mixes, AND IT’S FREE. What I like about this plugin is that it allows you to see the EQ range as a flat line so you instantly know if your midrange is low (a common problem for DJs turned producers) or if your bass is too heavy below 50hz (a common problem with headphone mixing or with speakers that don’t go too low.
So get it downloaded and stick it right at the end of your master buss. Hope it helps. Stu
