Classes > SpectrumEnh class > Methods > SpectrumEnh.Create method

Remarks

Creates an instance of the enhanced spectrum analyzer: being a graphical object, the spectrum analyzer needs to be associated to an existing window that will be used as a surface for the graphic rendering: this window can be changed at a later time through the SpectrumEnh.SetHwnd method. For development environments like WPF, where controls don't expose a HWND, the usage of the SpectrumEnh.CreateNew method should be preferred.

Once created, by default the enhanced spectrum analyzer is still not visible: you must make a call to the SpectrumEnh.Show method in order to display it.

Note that you can have a different enhanced spectrum analyzer for each of the allocated players.
