Offline Processing
Offline processes are useful for a variety of editing purposes and 
creative effects. For example, when the computer is too slow for 
real-time processing or when the editing requires more than one pass.
After the processing the audio file is permanently altered.
Applying Processing
Processing can be applied to a selection or to a whole file. For certain 
operations processing the entire file is necessary.
NOTE

Resample
You can change the sample rate of a recording. This is useful if the file 
that you want to use in a certain audio system was recorded at a sample 
rate that this system does not support.
Note the following:
• Sample rate conversion from a low frequency upwards does not 
improve the sound quality. The high frequencies that were lost 
cannot be restored by a conversion.
• When you resample to a lower frequency, high frequency material 
is lost. Therefore,...

Audio Montage
The audio montage is a multitrack non-destructive editing environment, 
which allows you to arrange, edit, play back, and record audio clips on 
multiple tracks.
Non-destructive means that when you delete or change a part of an 
audio file, the audio is not deleted or permanently changed. Instead, a 
set of pointers keeps track of all the edits, so these can be readily 
reversed. WaveLab LE provides comprehensive facilities for 
non-destructive editing.
