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

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

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
