1. I used to use the excellent (and free) SPAN analyser from Voxengo. I much prefer the DMG Analyser however and it is extremely customisable. If you are interested, try the demo as I have some cool presets in it (The TRK bank) that really show off some of the customisation possibilities DMG Audio: VST/AU EQ, Compression & Dynamic Processing Cheers.

SPAN is a free real-time “fast Fourier transform” audio spectrum analyzer AAX, AudioUnit and VST plugin for professional sound and music production applications.

SPAN provides you with a very flexible “mode” system which you can use to setup your spectrum analyzer preferences. You may specify Fourier block size in samples, FFT window overlap percentage, spectrum's visual slope. Beside that, you can choose to display secondary spectrum of a desired type (e.g. real-time maximum, all-time maximum). /character-vst-plugin.html. Spectrum can be smoothed out visually for an easier examination.

SPAN supports multi-channel analysis, and can be set to display spectrums from two different channels or channel groups at the same time. Spectrum's color can be chosen to taste.

SPAN also features output level metering with adjustable ballistics and integration time, EBU R128, K-system metering (including calibration K-system metering). SPAN displays level metering statistics, headroom estimation and true peak clipping detection. /darbukator-vst-free.html. Correlation metering is available as well.
