Installing and setting up
Additional audio settings
There are other settings in the Preferences that affect au-
dio playback and recording. We recommend that you try
the default settings before you change anything, since
these work well in most cases.
On the “Audio Card” tab, you will find the following set-
tings:
• Playback Buffer Number and Size.
These determine how much RAM memory is used for buffering when
playing back. If you get playback problems such as dropouts or glitches,
you should try to increase these values. Click the question mark icon in
the dialog for details.
• Recording Buffer Number and Size (not available when
using ASIO).
These determine how much RAM is used for buffering when recording. If
you get dropouts in the recorded audio, you should try increasing these
values. Click the question mark icon in the dialog for details.
On the Preferences–File tab, you will find the following
settings:
• Disk block buffer size.
Governs the buffer size used when WaveLab Studio is reading data from
the hard disk. If you experience problems in a read intensive scenario
(such as playing back an Audio Montage with a lot of simultaneous
clips), you should try changing this value.
If you change this setting, playback will stop when you leave the dialog.
• Use system cache.
When this is deactivated (default), WaveLab Studio reads files directly
from the hard disk, bypassing Windows’ file cache.
The option is available since it may remedy problems on certain systems
with slow disk drives. Note:
• If you activate this, avoid using large disk block buffer
size values!
• After activating this option, you need to close and re-
open all open files, for the setting to take effect!
About latency
In the Playback section of the Audio device tab, you will
find an indication of the current latency (at 16bit/44.1kHz
stereo). Latency is the delay between when audio is “sent”
from the program and when you actually hear it. The la-
tency in an audio system depends on the audio hardware,
its drivers and their settings. It’s usually possible to reduce
latency by lowering the number and size of the playback/
recording buffers. However, please note:
Temporary files
You also need to specify where WaveLab Studio should
store its temporary files. Temporary files are used for cer-
tain operations, such as WaveLab Studio’s extensive
Undo function (see “Undo and Redo” on page 20).
WaveLab Studio allows you to specify up to three differ-
ent folders for storing temporary files. If you have access
to more than one drive, saving your temp files on separate
drives (not partitions) can considerably speed up perfor-
mance.
For example, if your source files are located on the C:
drive, you could specify D:\temp and E:\temp as tempo-
rary folders.
This will not only improve performance, but also reduce
disk fragmentation.

With ASIO drivers, you may find these settings in the
ASIO Control Panel.

We recommend that you leave this option deacti-
vated!

While a very low latency can be crucial in a real-time
DAW application such as Steinberg Nuendo or Cu-
base, this is not strictly the case with WaveLab Stu-
dio. Here the important issues are optimum and
stable playback and editing precision. Therefore, you
should not try to reach the lowest possible latency
figures when working with WaveLab Studio. And
again, should you get dropouts, crackles or glitches
during playback, raise the Buffer Number setting on
the Preferences–Audio device tab.
