This article is a stub. You can help the Hydrogenaudio Knowledgebase by expanding it.

Experimental component

This component is considered an early prototype and it is under development as it was released as an early access. Bugs and issues with this component are expected and currently it has no CUI support.

A recreation of Musical Spectrum component for foobar2000 v2.x and 64-bit versions.

You can double-click the component window to switch between windowed and full-screen mode.

Configuration

Right-click on the component window to display the context menu.

Select Configure from the context menu to open the configuration dialog.

Transform

Method

Allows you to the selected the Time to Frequency domain transform. Currently Fast Fourier (FFT) and Constant-Q (CQT) transforms are implemented.

FFT

Groups the parameters that influence the Fast Fourier transform.

FFT Size

Specifies the size of the FFT window as a number between 64 and 32768.

Select Custom to specify a number that is not a power of 2. This will consume a lot more CPU power. Select Sample rate based to specify the size as a duration. F.e. 100ms of a track sampled at 44.1kHz will result in an FFT window of 4410 samples.

Summation

Determines which method is used to sum the coefficients of FFT.

   Minimum
   Maximum
   Sum
   Residual Mean Square (RMS)
   RMS Sum
   Average
   Median

Smooth lower frequencies

Smooth gain transition

Lanczos kernel

Determines the size of the Lanczos kernel. The kernel is used to create a smooth transition between the FFT coefficients resulting in a visual pleasing result.

Frequencies

Groups the parameters that determine the frequency range that will be displayed.

Distribution

Determines which parameters are used to generate the frequency bands.

   Linear: Generate frequency bands based on the frequency parameters.
   Octaves: Generate frequency bands based on the note parameters.
   AveePlayer: Generate frequency bands used by AveePlayer.

No. of bands

Specifies the number of frequency bands to generate (2 to 512) in the specified frequency range.

Frequency range

Frequency of the first and last band, 1Hz to 96000Hz.

Note range

Available when selecting the Octaves distribution. Select a range between the C note of octave 0 and B# of octave 11 (max. 144 notes or 12 octaves)

Bands per octave

Number of bands per octave (1 to 48)

Pitch

Tuning pitch (A4 = 440.0Hz), 1Hz to 96000Hz.

Transpose

Detuning offset (-24 to 24)

Scaling

Determines which frequency scaling function is used.

   Linear
   Logarithmic
   Shifted logarithmic
   Mel (AIMP)
   Bark
   Adjustable Bark
   ERB
   Cams
   Hyperbolic Sine
   Nth Root
   Negative exponential
   Period

Skew factor

Bandwidth

Determines the width of a frequency band. (0.0 to 64.0)

X axis

Groups the parameters that determine the way the X axis is displayed.

Mode

Determines which X axis to display.

   None: Hides the X axis.
   Bands: Center frequency of a band, every 10 bands.
   Decades: Fixed frequency range
   Octaves: Frequency of the C note of each octave
   Notes: C note of each octave

Y axis

Groups the parameters that determine the way the Y axis is displayed.

Mode

Determines which Y axis to display.

   Note: Hides the Y axis
   Decibel scale
   Logarithmic

Amplitude range

Determines the minimum and maximum amplitude, expressed in decibel (dB), to display.

Amplitude step

Determine the step size between the min. and max. amplitude.

Use absolute

Gamma

Bands

Color scheme

Specifies the color scheme used to render the spectrum.

   Solid color
   Custom
   Prism 1
   Prism 2
   Prism 3
   foobar2000
   foobar2000 Dark Mode
   Fire

Double-click a color to modify it. Modifying a color automatically selects the Custom color scheme. Press the Add' button to add a color, Remove to remove a color, Reverse to reverse the color scheme.

Smoothing

Specifies how the spectrum will be smoothed over time.

   Average
   Peak

Smoothing factor

Specifies the strength of the smoothing (0.0 to 1.0)

Peak mode

Specifies how the peak indicators are rendered.

   None
   Classic
   Gravity
   AIMP
   Fade Out

Hold time

Specifies how long a peak value will be held steady.

Acceleration

Specifies the acceleration used to modify the peak value.

Colors

Click any of the colors to modify.
