out, for example, what consonants they represent.
Gain Reduction Indicator
This red-note area gives a real-time indication of the shape and amount of occurring
gain reduction. The shape follows the slope indicators, and roughly corresponds to
the shape of the pink FFT region (see 7 above).
Threshold Line
This line shows the current threshold level. The line will wander up and down as the
general signal level rises and falls (unless you have switched the threshold to
‘Absolute’ mode). If you move the threshold line while there is no signal or a silent
signal present, you are setting the presumed level that will occur when the signal
returns. This will be indicated on the graph as a dotted line (or ghost threshold line).
Central FFT Peak
This holds for your attention that important frequency in the band window, which
has the peak energy. This will most likely indicate a consonant or fricative that you
may want to deal with. Clicking on this peak will then centre the band filter to this
frequency, and help to isolate it.
Zoom In/Out
This allows you to zoom-in or zoom-out when clicking and dragging. Additionally,
you can use the jog/scroll wheel forward/backward to achieve the same thing.
Useful Shortcuts
Jogwheel up/down or forward/backward to zoom in/out. Left/Right-Click anywhere
to centre the band filter to that point.
