Voxengo SPAN
Voxengo SPAN is a free real-time FFT spectrum analyzer plugin for audio and music production applications. It analyzes stereo, mono, mid-side, and surround signals, including 5.1 and 7.1, and can display spectra from two channels or channel groups at once. Metering includes EBU R128 and K-system readings, RMS and true-peak measurements, clipping detection, and stereo correlation. Users can adjust FFT block size, window overlap, visual slope, smoothing, and a secondary spectrum display. Other functions include output power statistics, channel routing and grouping, presets, undo and redo, and A/B comparisons. SPAN is available for Windows and macOS in VST, VST3, and AAX formats, with AudioUnit also listed for Mac. The maker lists Windows XP and later and macOS 10.12 and later, with a 2.5 GHz dual-core or faster processor and at least 4 GB of RAM. Spectrum import and export for track comparisons is a SPAN Plus feature; the free plugin workaround works only in some hosts.
