The dialog contains the following parameters:
Define Bars section
In this section, you set the length of the selected audio and the time signature:
•Bars
If you use the tempo setting (see below), specify the length of the 
selected audio here, in bars.
•Beats
If you use the tempo setting, specify the length of the selected audio 
here, in beats.
•Sign.
If you use the tempo setting, specify the time signature here.

•Use Locators
Clicking the diamond-shaped button below the Range fields sets the 
Range values to the left and right Locator positions, respectively.
Time Stretch Ratio section
The Time Stretch Ratio determines the amount of time stretch as a 
percentage of the original length. If you use the settings in the Resulting 
Length section to specify the amount of time stretch, this value will change 
automatically.

Here you can choose a preset...

Detect Silence

Detect Silence
The Detect Silence function 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.
• To open the Detect Silence dialog, select one or several audio events in the 
Project window or the Audio Part Editor. On the Audio menu, open the 
Advanced submenu and select “Detect Silence”.
If you select more than one event, the...

Min. time closed
Determines the minimum time that the function will remain “closed” after the 
audio level has dropped below the Close Threshold value.
Set this to a low value to avoid removing sounds.
Pre-roll
Allows you to cause the function to “open” slightly before the audio level 
exceeds the Open Threshold value. In other words, the start of each “open” 
section is moved to the left according to the time you set here.
This is useful to avoid...

You can make the following adjustments:
• With the zoom slider below the waveform to the right, zoom in and out on the 
waveform.
You can also click in the waveform, keep the mouse button pressed, and 
move the mouse for zooming. Move the mouse down to zoom in and move it 
up to zoom out.
• If you have zoomed in on the waveform, it may not be completely visible 
anymore. In this case, the scrollbar to the left of the zoom slider allows you to 
scroll...

NOTE
If you have selected more than one event and did not activate the “Process all 
selected Events” option in the Output section, the dialog opens again after 
processing, allowing you to make separate settings for the next event.
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...

•From Stereo
When analyzing stereo material, there is a pop-up menu with the following 
options:
Mono mix – the stereo signal is mixed to mono before analyzing.
Mono left/right – the left or right channel signal is used for analysis.
Stereo – both channels are analyzed (two separate spectrums will be 
displayed).
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...

Statistics

• If you analyze stereo audio and selected the “Stereo” option in the first dialog, 
the graphs for the left and right channel are superimposed in the display, with 
the left channel graph in white and the right channel graph in yellow.
The display in the upper right corner shows the values for the left channel – to 
see the right channel values, hold down [Shift]. An “L” or “R” is displayed to 
indicate which channel values are shown.
6. You can leave the...

Standard – Mix
This mode preserves the rhythm and minimizes the artifacts for pitched 
material that does not meet the above criteria (i.
 e. with a less homogenous 
sound character).
This preset is selected by default for audio that is not categorized.
Standard – Custom
This preset allows you to manually tweak the time stretching parameters (see 
below). By default, the settings that are shown when you open the dialog are 
those of the last...
