Spectrum Analyzer Window

The Spectrum Analyzer employs a Fast Fourier Transform to derive the frequency spectrum of the sound as it comes off the sound card. This spectrum is then displayed in the Spectrum window as a series of graphics. Below the frequency spectrum, left and right volume are displayed. 

Six buttons adorn the right side of the Spectrum Analyzer: Left & Right, Center, Split, Combined, Trails and Gradient.

  • Left & Right - When this button is selected, frequency information for both left and right channels is displayed.
  • Center - When this button is selected, monaural frequency information is displayed. This button and the Split button cannot be depressed at the same time.
  • Split - When this button is selected, the left, right and center channel frequency information is physically separated in the graph. 
  • Combined - Opposite of split.
  • Trails - When this button is selected, the spectrum graphics will show trails at the peak values. Trail duration is adjusted by right-clicking on the spectrum and choosing to configure the spectrum.
  • Gradient - When this button is selected, the spectrum is displayed using a gradient of colors ranging from the low color to the high color. These colors can be selected by right-clicking on the spectrum and choosing to configure the spectrum.

A Gain slider is also provided to help adjust the gain of the signal into the spectrum analyzer. This has no effect on volume - to change volume, look to the Console or Mixer windows.

Right-click on the spectrum to get a context menu that will allow you to turn spectrum trails and hi resolution on/off, as well as perform other functions.
