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.
Right-click on the component window to display the context menu.
Select Configure from the context menu to open the configuration dialog.
Allows you to select the Time to Frequency domain transform. Currently Fast Fourier (FFT) and Constant-Q (CQT) transforms are implemented.
Selects the window function that will be applied to the Time data.
Allows you to tweak window functions that support a parameter.
Skew factor for the window function.
Allows you to select that audio channels that will be used to calculate the transform.
Groups the parameters that influence the Fast Fourier transform.
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.
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
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.
Groups the parameters that determine the frequency range that will be displayed.
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 of the first and last band, 1Hz to 96000Hz.
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)
Tuning pitch (A4 = 440.0Hz), 1Hz to 96000Hz.
Detuning offset (-24 to 24)
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
Determines the width of a frequency band. (0.0 to 64.0)
Groups the parameters that determine the way the X axis is displayed.
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
Groups the parameters that determine the way the Y axis is displayed.
Determines which Y axis to display.
Note: Hides the Y axis Decibel scale Logarithmic
Determines the minimum and maximum amplitude, expressed in decibel (dB), to display.
Determine the step size between the min. and max. amplitude.
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.
Enable the check box to see a background behind every band of the spectrum.
Enable the check box to see a tooltip with the center frequency and when appropriate, the name of the note, of the frequency band.
Specifies how the spectrum will be smoothed over time.
Specifies the strength of the smoothing (0.0 to 1.0)
Specifies how the peak indicators are rendered.
None Classic Gravity AIMP Fade Out
Specifies how long a peak value will be held steady.
Specifies the acceleration used to modify the peak value.
Click any of the colors to modify.
