Spectral Peaks Settings

Figure 1. Spectral Peaks Settings

This page configures the detection and display of spectral peaks on the spectrogram. A spectral peak is a local maximum in the spectrum — a frequency that stands out above its neighbours — and is typically a harmonic, a formant, or a resonance.

Display Peaks on Spectrogram

When checked, the strongest spectral peaks at each time position are drawn on top of the spectrogram. Uncheck to compute peaks without drawing them on the spectrogram (the Statistics Pane still lists them).

Color

The color used to draw peak markers on the spectrogram. Click the color button to change it.

Number of peaks

How many peaks to detect per analysis frame, from 0 to 12. Higher values reveal more spectral structure but clutter the display. The default is 2.

Min Intensity

Spectral peaks quieter than this threshold (in dB) are ignored. Raise it to suppress noise-floor peaks; lower it to find weaker partials. The default is −60 dB.

Frequency Range

The lowest and highest frequencies considered when detecting peaks. Peaks outside this band are skipped, which is useful for ignoring mains hum at the low end or noise above the signal’s useful range at the high end.
