Spectrum Analyzer Screen

The Spectrum screen shows a real-time frequency spectrum of the audio currently being processed. It updates continuously during playback.

The spectrum is displayed as a frequency-domain graph:

  • X axis — frequency (logarithmic scale, 20 Hz – 20 kHz)
  • Y axis — level in dBFS
  • Curve — instantaneous spectrum with configurable peak-hold

The analyzer reads signal data after the full plugin chain, so it reflects the post-EQ frequency content.

The Spectrum Analyzer plugin (which powers this screen) can be configured directly:

ParameterDescription
FFT sizeFrequency resolution (larger = finer bins, higher latency)
SmoothingTime-domain averaging to reduce jitter
TiltAdds a rising shelf to compensate for pink noise statistics
Peak holdDuration peaks are held before falling
Min / Max dBVertical scale range

Add or adjust the Spectrum Analyzer plugin from the Plugins screen. See Spectrum Analyzer plugin reference for all parameters.

  • Use the spectrum to visually verify EQ changes — filter peaks and dips should be visible
  • Enable tilt correction when analyzing pink noise or music to get a visually “flat” display
  • Comparing spectrum before and after an EQ plugin is easier with the A/B Compare plugin
