How to use the embedded Visual Feedbacks
This version of the control comes with four embedded Visual Feedbacks, internally implemented as COM objects: this object oriented approach allows to access each of the Visual Feedbacks as a control's property. The available feedbacks are the following:
These Visual Feedbacks, through the call to the respective Create methods, need to be associated to an existing window that will be used as a surface for the graphic rendering; for this purpose we suggest the use of a PictureBox control with "Flat" appearance. Note that you can have separate Visual Feedbacks for each of the allocated players.
Implemented through the
VUMeter object and accessible through the
VUMeter property, must be created through a call to the
VUMeter.Create method and can be shown/hidden at any time through the
VUMeter.Show method. This object exposes the following properties and methods that allow the customisation of the graphic rendering:
BandType: determines if the VU Meter will be a mix of the Left and Right channel or if each channel will have a dedicated "band" (default).
HasPeaks: determines the "peaks" visibility.
ZoomPerc: determines the height zoom percentage of bands.
below you can see a sample of the embedded VU-Meter:
If you shouldn't like the graphic representation of the embedded VU-Meter, note that you can implement your own VU-Meter graphics, driven by the values received through the
VUMeterValueChange event.
Implemented through the
Spectrum object and accessible through the
Spectrum property, must be created through a call to the
Spectrum.Create method and can be shown/hidden at any time through the
Spectrum.Show method. This object exposes the following properties and methods that allow the customisation of the graphic rendering:
BandWidth: determines the width in screen pixels of the "bands".
HasPeaks: determines the "peaks" visibility.
ZoomPerc: determines the height zoom percentage of bands.
below you can see a sample of the embedded Spectrum and, on the right, a zoomed detail of the Spectrum "bands":
If you shouldn't like the graphic representation of the embedded Spectrum, note that you can implement your own Spectrum graphics, driven by the values obtained through the
Spectrum.GetTable method which can be called after receiving the
SpectrumValueChange event.
Implemented through the
Oscilloscope object and accessible through the
Oscilloscope property, must be created through a call to the
Oscilloscope.Create method and can be shown/hidden at any time through the
Oscilloscope.Show method. This object exposes the following properties and methods that allow the customisation of the graphic rendering:
Type: determines the type of drawing used to render the line.
ZoomPerc: determines the height zoom percentage of the line.
below you can see a sample of the embedded Oscilloscope:
Implemented through the
Waveform object and accessible through the
Waveform property, must be created through a call to the
Waveform.Create method and can be shown/hidden at any time through the
Waveform.Show method. This object exposes the following properties and methods that allow the customisation of the graphic rendering:
Resolution: determines how frequently vertical lines are drawn on the screen (by default every 30 milliseconds).
ZoomPerc: determines the zoom percentage of the lines drawn.
below you can see a sample of the embedded Waveform display:
