it easy to back them up or copy them to another computer. You can change the location of
this main Presets folder via Global Preferences>Setting location . You have the choice
of the following locations:
ˆ a standardized location that can be accessed by all users of the computer. That is, all
users will share the same settings.

4.6.16 Rendering
To Render effects into a temporary or final file, you use the Render function (note that the
"Save" function from the File menu does not Render!). The Render function is part of the
Master Section and in other applications is sometimes referred to as "bouncing down" or
"mixing down".
Rendering a file "prints" all audible settings and effects that the audio is being routed through
in the Master section, to the...

the resultant file with the effects rendered. Remember to save a copy of your session
before doing this so you can go back and edit any levels or effects if you need to.
For more information about choosing settings when rendering see the
Render Wave window
and Render Montage window . For more information on applying effects see the Master

ˆ Define shortcut for the current setting - when available, this allows you to assign a
shortcut to the current preset using either a key shortcut, keyword or via a MIDI trigger.
For example, if you have a preset to normalize audio at -0.1 dB and you assign it a
key shortcut then everytime you execute the shortcut, the preset is applied to the audio
selection, without the need to open the dialog.

When you render a file you can choose the format of the new Audio File and whether you
wish to create a new file or render the file in place. When the file is rendering you will
see a progress bar in the status bar.In WaveLab you can also view this Progress bar in the
Background tasks window (a shared tool window that can be set to float independently).This
allows you to monitor the progress of rendering, pause...

tasks such as trimming and cropping a file at specific times, for example. You can write
scripts that perform other basic editing commands, apply offline processing, place markers,
and display information about the active file. You can script commands to edit the active
Audio File or the active Audio Montage. If you have some experience of programming with
modern scripting languages you should have no problem writing utility scripts for WaveLab.
The WaveLab Scripting language is based on...

Scripting window contexts
It is important to note that certain scripting commands are only available in the Audio File
Workspace and others only in the Audio Montage Workspace. Others are "global", meaning
you can use them in either Workspace. To begin exploring the WaveLab Scripting Language

Many functions make use of presets as an argument. For example, the normalize() function
accepts a preset as an argument:
activeWave.normalize("myPreset");
The advantage is that you don't need to specify many parameters in your scripts, instead you
can use the corresponding dialog to define the settings of a particular function, and then
save them as a preset file. Since each type of...
