A spectrum analyzer component that displays FFTs of each separate channels.

Options

Settings window for Channel Spectrum panel

General

Refresh interval

Visualization rendering interval in milliseconds (frame rate in FPS is inversely proportional to this parameter; ~16ms = 60fps)

Show peaks

Visualizes spectral peaks, with falling animation similar to WMP bars visualization

Range scale

The dB range for this visualization

Logarithm scale

Whether or not amplitude scale is more of logarithmic/dB kind

Note: This is for old FFT method only

Linear scale (frequency)

Makes the frequency scale linear, otherwise a pseudo-logarithmic one similar to Mel scale

Bar width

The width of the visualization bars. Higher width in px means lower number of bands

Edge style

Style for the panel border

Color mode

Drawing style for the visualization bars

FFT size

The window size for the FFT algorithm

Window function

The window function for the FFT visualization

Note: New method uses Gaussian window instead of rectangular

Coloring

Bar color 1

First color of the visualization bars

Bar color 2

Second color for the visualization bars

Peak color

The color for the spectral peaks

Background color

The color for the background

Grid color

The color for the frequency/amplitude grid

Transparent background

Makes the background transcluscent

Fast pseudo-transparent mode

Performs approximate transparency for background instead of slower more exact ones.

Frequency/amplitude grid

Show frequency ticks

Shows the frequency grid

Show amplitude ticks

Shows the frequency grid

Specifications

Frequency grid is spaced in 2kHz increments from DC offset frequency to approximately the Nyquist frequency for short ticks, where as 10kHz increments for long ticks.

dB grids are displayed in 10dB and 20dB increments for short and long ticks respectively down from 0dB
