VuMeter.KeepCountOfVolume method

Previous pageReturn to chapter overviewNext page

Remarks

 

Specifies if the VU-Meter must keep count of the volume set into the DirectSound buffer of the given player, through a previous call to the StreamVolumeDirectSoundBufferSet method, in order to calculate the volume level. This method has no effect without a previous call to the VUMeter.Create method.

 

For further details about using the embedded VU-Meter refer to the VUMeter object section.

For details about using Visual Feedbacks refer to the How to use the embedded Visual Feedbacks section.
