Detect Silence
The Detect Silence function on the advanced submenu of the Audio 
menu isn’t really a processing function, since it doesn’t actually affect 
the audio clip. Instead, it searches for silent sections in an event, and 
either splits the event, removing the silent parts from the project, or 
creates regions corresponding to the non-silent sections. Proceed as 
follows:
1.Select the event in the Project window or the Audio Part Editor.
You can...

sections will be considered “silent”, according to your settings.
Setting Description

The Spectrum Analyzer
This function analyzes the selected audio, computes the average 
“spectrum” (level distribution over the frequency range) and displays 
this as a two-dimensional graph, with frequency on the x-axis and level 
on the y-axis.
1.Make an audio selection (a clip, an event or a range selection).
2.Select “Spectrum Analyzer” from the Audio menu.
A dialog with settings for the analysis appears.
The default values are chosen to give good results...

3.Click the “Process” button.
The spectrum is computed and displayed as a graph.
4.You can adjust the display with the settings in the display window:
Setting Description
dB When this is activated, the vertical axis shows dB values. When it is 
deactivated, values between 0 and 1 are shown.
Freq. log When this is activated, frequencies (on the horizontal axis) are dis-
played on a logarithmic scale. When it is deactivated, the frequency 
axis is linear....

5.If you move the mouse pointer over the graph, a crosshair cursor fol-
lows the graph curve and the display in the upper right corner shows 
the frequency/note and level at the current position.
To compare the level between two frequencies, move the pointer to one of the frequen-
cies, right-click (Win) or [Ctrl]-click (Mac) once and move the pointer to the second fre-
quency. The delta value (the difference in level between the current position and the...

Background
The Sample Editor allows you to view and manipulate audio at the au-
dio clip level, by cutting and pasting, removing or drawing audio data 
or applying effects. This editing can be called “non-destructive”, in the 
sense that you can undo changes or revert to the original versions at 
any point, using the Offline Process History. 
For details, see the section about non-destructive processing on page 
360 and the description of the Offline Process History on...
