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. Higher values have better frequency resolution at the cost of worse time resolution and vice versa. Must be a power of two.
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
