Spectrum Analyzer averages the spectrum of a whole file and shows where energy lives across the frequency range, using a monochrome density plate and a single ink curve instead of a saturated heatmap.
The FFT runs in your browser on the file you already loaded, so opening this tool after SCAN costs nothing. It is a static reading of a file; there is no live microphone mode.
Drop a file and the average spectrum is measured locally.
Darker marks mean more average energy in that frequency band.
Use the peak, centroid and low/mid/high energy shares to summarise the balance.
