If you choose to burn an ISO disk image the dialog allows you to select a filename for the
resultant ISO file. Choosing a CD-R or DVD-R drive displays choices for setting the speed
or to try a test burn.
Important note for Mac OSX users
When using CD-R/DVD-R drive on Apple OSX computers for importing or burning it is
important to note the following. If you insert a optical CD or DVD disk in the drive while the
drive is not selected in WaveLab for import or burning, WaveLab will not...

drag points or value sliders to adjust the cross fade envelope. Click Apply to process the
cross fade.
Post cross fade
This tab allows you to cross fade the loop back into the audio after the end of the loop. This
is done by mixing a copy of the loop back into the audio. Use the envelope drag points or
value sliders to adjust the cross fade envelope. Click Apply to process the post cross fade.
Using the "Copy" button you can insert multiple copies of the loop into the...

11.2.1 Phasescope
The Phasescope indicates the phase and amplitude relationship between two stereo chan-
nels. It is only really relevant when monitoring stereo audio material.

ˆ Generally, the more you can see a "thread" shape, the more bass there is in the signal;
the more "spray-like" the display, the more high frequencies are in the signal.
Phase Correlation meter
At the bottom of the display, you will find a Phase Correlation meter, which shows the same
information but in a different way:
ˆ The green line shows the current phase correlation, while the two red lines show the
recent peak minimum and maximum values, respectively...

ˆ The VU (Volume Unit) meters measure the average loudness (RMS) of each channel.
These meters have a built-in inertia, evening out loudness variations over a user-defined
time span. If you are monitoring playback or audio input, you will also note two vertical
lines following each VU meter bar, seemingly "trying to reach" the current RMS value.
These lines indicate the average of the most recent minimum RMS values (left line)
and the average of the most recent maximum RMS...

Making settings
By opening the Settings dialog you can adjust the display colors, and choose to activate
Auto-zoom or not. With Auto-zoom activated, the display is optimized so that the highest
level reaches the top of the display at all times. The Settings dialog can be accessed through
the Functions >Settings... menu, or by using the
icon.
The Oscilloscope can be found in the Metersmenu of the Audio Files and Audio Montage
Workspaces. It can be used either as a floating...

When to use the Bit Meter
ˆ To check whether dithering is necessary or not. As a rule, if you're playing back or
mixing down to 16 bits, and the Bit Meter shows that more than 16 bits are used, you
should apply dithering.
ˆ To see the "actual" resolution of an Audio File. For example, even though a file is in 24
bit format, only 16 bits may be used. Or, a 32 bit file may only use 24 bits (in this case,
the "below" segment would not be lit). For this purpose, the...

ˆ The current frequency spectrum is shown as a linear graph.
ˆ Spectrum "peaks" are shown as a short horizontal lines, indicating recent peak/maxi-
mum values.
Snapshots
By using the "Add snapshot" and
"Erase last snapshot" buttons, you can take and erase
snapshots of the current spectrum. These will be superimposed over the current peak spec-
trum graph, in a color you can customize, until you click the icon again to take a new snapshot.

"Export FFT data as ASCII" from the Options pop-up menu. The resulting text file can then
be imported into applications that allow graph plotting from text files (Microsoft Excel, for
example).
The Spectrometer can be found in the Metersmenu of the Audio Files and Audio Montage
Workspaces. It can be used either as a floating window, or docked in the Workspace or the
Control Window .
