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.
