Spectrum
Fill Spectrum
Allows you to display the real-time spectrum as a solid graph
as opposed to a line graph. This option can be used to dif-
ferentiate the real-time spectrum from the peak hold spec-
trum.
Show Peak Hold
Toggles whether Nectar displays and holds the peaks of the
spectrum analyzer
Spectrum Type
Lets you select between three types of spectrums:
Linear: a continuous line connecting the calculated points of
the spectrum
1/3 octave: splits the spectrum into bars with a width of 1/3 of
an octave. Although the spectrum is split into discrete bands,
this option can provide excellent resolution at lower fre-
quencies.
Critical bands: splits the spectrum into bands that cor-
respond to how we hear, or more specifically how we dif-
ferentiate between sounds of different frequencies. Each
band represents sounds that are considered "similar" in fre-
quency.
Peak Hold Time
(ms)
You can click on the Peak Hold time to select between spe-
cific hold times in milliseconds or Infinite, where the peak is
held indefinitely. You can reset the peaks by clicking on the
spectrum.
Window Size
Controls the trade off between frequency and time resolution
in the spectrum. Higher values will let you see smaller peaks
in the spectrum, but the spectrum will update more slowly.
Overlap
Controls how often the spectrum updates. More overlap will
cause the spectrum to update more frequently, at the
expense of increased CPU usage.
Window
Selects a window type for the spectrum. In most cases the
default window type will work well, but you can choose from a
variety of window types. Each window type has different amp-
litude and frequency resolution characteristics.
