Time Stretching
Time stretching is an operation that allows you to change the length of 
a recording without affecting its pitch.
With time stretching you can make audio material longer or shorter. This 
function is most often used to make a section of audio fit in with some 
other material. You select the material to be stretched and use the 
options in the Time stretching dialog to find a stretch factor. This is 
done by specifying a length or a tempo, according...

and beats.

About the DIRAC Time Stretching Processor
The DIRAC engine is a high quality time stretcher. It produces the best 
quality results possible, but takes longer to process.
Pitch Shift
Pitch shift allows you to detect and to change the pitch of a sound, with 
or without affecting its length. This is useful for fixing an off-key vocal 
note in a live recording, or tuning the pitch of a kick drum sample to fit a 
particular song, for example.

Resample

Pitch field
Specifies the resulting pitch.
Length preservation
Specifies how the length of the selection is affected by the 
operation:
• A setting of 100 means that the length of the audio remains 
unchanged.
• A setting of 0 means that the program behaves like a tape 
recorder, when the speed of its tape is changed. For example, if 
you raise the pitch by one octave, the audio is half as long.
• Intermediate values give results in between these two extremes.

Resample
155
• When you resample to a lower frequency, high frequency material 
is lost. Therefore, converting down and then up again leads to a 
degradation in sound quality.
NOTE
Using the Crystal Resampler in the quality mode High to change the 
sample rate results in the same quality as when using Process > 
Resample in the Audio Files workspace. However, that is only the case 
if the sample rate in the Sample rate dialog exists in the values of the 
Crystal Resampler Sample rate...

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 Elements provides comprehensive facilities for 
non-destructive editing.
Features include both...
