From this with a spectrum analyzer

to something like this

Does ableton have a multitrack- spectrum analyzer? Like this one




Yet, it can help a bit, if you have bad reflections in your work space. You shold then also have a good pair of headphones, as a second view. Sometimes its better to do a second check on headphones, then your home hifi or car hifi. Because there can be bad reflections there aswell. In headphones theres no reflections coloring the sound. In my home studio, if I move 3 meters Back from my seat, the bass get pitced up one whole note! I also get -3db from 80hz and down. I found out this while checking my mixes in others studios.And forget using a spectrum analyzer for this, many great sounding tracks don't LOOK the same at all. Focus on what you hear, only use an analyzer to help spot a particular problem if you must.
