Causes the system to issue an audible tone. (Windows Vista 64-bit) This VI might not work correctly if use system alert? is FALSE.
frequency (Hz) is the frequency of the tone in Hertz. LabVIEW ignores this parameter when use system alert? is TRUE.
duration (msec) is the duration of the tone in milliseconds. LabVIEW ignores this parameter when use system alert? is TRUE.
use system alert? specifies whether LabVIEW uses the default system alert and ignores frequency (Hz) and duration (msec). If FALSE, this VI makes a synchronous beep using the specified frequency and duration. The default is TRUE.
