A spectrum analyzer visualisation which measures and displays frequencies corresponding to musical notes (eg. A4 = 440Hz). Compatible with the default user interface and Columns UI.

Options

Spectrum Options window.

The following options can be accessed by right-clicking the spectrum and selecting "Options".

Processing

Notes
Increase or decrease the visible notes, from C0 (16.35 Hz) to A11 (56.32 kHz).
Default: A1 - C9
Amplitude
Set the visible amplitude, from -80dB to 80dB.
Default: -60dB - 0dB
Channels
Select any number of 18 available input channels.
Default: All Channels
Interval
Set the FFT hop size in milliseconds, frame rate is inversely proportional to Interval parameter.
Default: 25 milliseconds
FFT size
Set the FFT (fast Fourier transform) size, from 1,024 samples to 32,768 samples.
Default: 8,192 samples
Pitch (A4)
Set the frequency for A4. To maintain accuracy, this should be set to 440 Hz.[1]
Default: 440 Hz
Transpose
The number of semitones by which to transpose the visible notes, from -12 to 12.
Default: 0 semitones

Peaks

Hold time
Set the amount of time in milliseconds (ms) before the peak drops.
Default: 500 ms
Gravity
Set the speed at which the peaks drop.
Default: 50 dB/s²
