OnVUMeterValueChange event

Previous pageReturn to chapter overviewNext page

Remarks

 

Occurs whenever there is a change on the VU-Meter peak values: this event, generated every 15 milliseconds, can be useful if you need to implement your own VU-Meter graphical representation.

 

This event replaces the usage of the CallbackVuMeterValueChange delegate and is only intended for usage with applications developed using Visual Basic 6 (which results unreliable when dealing with delegates and callbacks) and, in order to be enabled, requires a call to the COMEventsEnable method.

 

For details about using graphic bars refer to the How to perform custom feedbacks rendering using graphic bars section.
