Settings on your computer

Here are a few basic points to help you set up your

computer for best performance with audio applications.

Do not run other applications. You will probably use

your computer for applications other than audio,

but we recommend that you avoid running other

applications at the same time you are running

audio programs. Processing digital audio places a

considerable load on your computer.

This means that if you are running other applications

(especially graphics or Internet tools) at the same time

as your audio application, the processing may not

happen fast enough.
