Presets tab
The Presets tab features a list of EQ presets, with self-ex-
planatory names.
• To load a preset, select it in the list and click the “Load”
button.
• If you have modified a preset which you wish to save,
use the “Update” button.
• You can also save your own presets by typing in a name
and clicking the “Add” button.
Convert sample rate
This function allows you to change the sample rate of a re-
cording. This is very convenient if you have a file that you
wish to use in a certain audio system and find that the file
was recorded at a sample rate this system doesn’t sup-
port. Please note that Sample rate conversion can also be
done as part of the Saving process (see “Saving in an-
other format (Save as…)” on page 51).
Please note the following:
• Sample rate conversion from a low frequency upwards does
not improve sound quality. The high frequencies that were lost
due to a low recording frequency cannot be restored by a
conversion.
• When you sample rate convert down to a lower frequency,
high frequency material will be lost (this is part of the mathe-
matics behind digital audio). Therefore, do not convert down
and then up again, since this will lead to a degradation in
sound quality (unless that’s exactly what you’re after). Instead,
use the Undo and Redo functions.
Performing the sample rate conversion
1. Select Convert sample rate from the Process menu.
This opens the Sample Rate dialog.
2. Select the desired sample rate from the pop-up menu
and click OK.
If you want to change any other audio properties (e.g. the bit resolution or
stereo/mono status), you can do this in one of two ways:
• Open the Audio Properties dialog from the Edit menu and
make the desired settings (see “Editing audio properties” on
page 56).
• Open the Audio File Format dialog by selecting “Save as” on
the File menu and clicking the Properties button in the lower
section of the dialog (see “Saving in another format (Save
as…)” on page 51).
Support for reNOVAtor™
If this audio restoration plugin is installed on your system,
you can select it from the Tools menu.
This menu option is enabled if a wave window is open and
an audio selection is active (it can be both channels or a
single channel).
Selecting “reNOVAtor…” from the menu opens this plug-
in and the active audio range is edited. The plug-in win-
dow is non-modal, hence you can work in WaveLab Stu-
dio without closing the plug-in.

Sample rate conversion is always applied to the en-
tire file. Any selection you have made is not used in
any way for this operation.
