Sounds dialog box
Nexus can play sounds through your PC's speakers to alert you when a Nexus event has taken place (for example, operation completion, system status, and issues). This keeps you informed of system status while you're still in the volume, so that you don't have to spend time returning to the PC to look at the screen.
You can access this dialog box from the Window menu or by pressing F6.
By default, Nexus uses speech sounds to alert you to the following events:
- Calibration start
- Wand Wave complete
- Calibration complete
- Calibration failed
- Origin set
- Capture started
- Capture ended
- Capture failed
- Camera bumped
- Pipeline ended
- Pipeline failed
Nexus is supplied with a set of default sound files (.wavs). You can modify the sounds that are used for each event and you can turn off sounds individually or turn off all sounds.
To turn off all sounds, in the Sounds section, clear the Enabled check box.
