Improving Performance with Digital Audio

flow of audio data to your sound card, thereby reducing the possibility

of dropouts.

To disable the hardware acceleration on your graphics card: Launch

Control panel (Start-Settings-Control panel). Double-click the Display

icon. Select the Settings tab. Click on the Advanced Properties button.

Select the Performance tab. Move the slider for hardware acceleration

one notch at a time toward ‘none’ and re-test your recording/playback

after each such adjustment. If problem(s) persist, leave the slider at

‘none’ and proceed with the next step.

• Try Using the Windows driver for your specific sound card (instead of

the manufacturer's driver).

• Try using the standard VGA/SVGA drivers provided with Windows

(instead of the drivers provided by the manufacturer).

• Check your video card manufacturer's web site for a later driver

version. If a newer driver is available, download it and install it on your

computer following the manufacturer's instructions.

• If you have an STB Velocity 128 card, and your graphics card was

configured and shipped with a new PC, you may want to check the

PC vendor’s website (instead of STB’s site) to see if they offer a

driver update for the STB card. PC vendors often will customize

drivers to their specific needs and you should use their driver

updates.

• Try reducing the number of colors used by your video card. 16-, 24-, or

32-bit true color display settings can severely hamper real-time audio

performance on some computers; using fewer colors allows your

computer to spend more of its processing time on audio and MIDI.

You can adjust color depth by right-clicking on your Windows desktop,

clicking Properties, clicking on the Settings tab, and selecting a suitable

entry in the Colors listbox. Also, try reducing the display resolution. Re-

test your audio playback/recording with these changes.

• If you have one of the following specific video cards, applying the

following card-specific .INI file settings can reduce PCI bus contention

problems. Be sure to check out http://www.cakewalk.com/Support/
