In the 24/32bit of bit depth era, there's no need to mix hot. Just turn your monitors louder to compensate the fact that you're mixing on a lower peak level. What that means, is that they don't work in their sweet spot of their processing algorithm and also a bus compressor would struggle too hard to tame everything instead of just gluing subtly with a GR of just 1 or 2db. If you do load some plugins before the limiter while the limiter already started the gain reduction (against clipping) then i'm sure that all the plugins before the limiter you loaded are internally clipping as well. If there's no headroom, then there's no room for enhancing your master. The headroom is actually for any mastering processing before the Limiter. If you load a Limiter and the whole song is already clipping like 1 or 2 db, there's absolutely no headroom for extra processing (plugins) before the limiter.

Try to never exceed -6 or -5 db on your master bus (as an overall volume for your whole project, not for the instruments particullary). Correlation metering is available as well.Click to expand.It helps ONLY if you mix too hot. SPAN displays level metering statistics, headroom estimation, and true peak clipping detection. SPAN also features output level metering with adjustable ballistics and integration time, EBU R128, K-system metering (including calibration K-system metering).

SPAN supports multi-channel analysis, and can be set to display spectrums from two different channels or channel groups at the same time. Spectrum can be smoothed out visually for an easier examination. Beside that you can choose to display secondary spectrum of a desired type (e.g. You may specify Fourier block size in samples, FFT window overlap percentage, spectrum's visual slope. SPAN provides you with a very flexible “mode” system which you can use to setup your spectrum analyzer preferences. SPAN is a free real-time “fast Fourier transform” audio spectrum analyzer AAX, AudioUnit, and VST plugin for professional sound and music production applications.
