Adds a new wave range that will be displayed over the waveform's graphics.
Inside the screenshot below you can see 2 examples of wave ranges, each with its own set of colors. Please note that "wave ranges" are a different concept respect to "waveform selection": you can only have one single "waveform selection", whose positioning can be managed through code or through mouse movement, but you can have multiple "wave ranges" managed through code without any mouse management for changing the positioning.
When the WaveformAnalyzer.ViewModeSet method has been invoked with the nMode parameter set to WANALYZER_VIEW_MODE_SPECTRAL, wave ranges are not fully displayed because their presence would cause a loss of colors of the spectral view so they will be only rendered on the top and of the bottom of the waveform area as senn on the screenshot below:
Wave ranges can be moved through code using the WaveformAnalyzer.GraphicItemHorzPositionSet method.
During playback of the loaded sound, the WaveAnalyzerWaveRangeReached event is generated when playback position reaches the start position of the wave range and the WaveAnalyzerWaveRangeLeaved event is generated when playback position leaves the end position of the wave range.
This method fails if no sound is currently loaded into the editor
The wave range is automatically destroyed, as all of the other existing graphic items, when the loaded sound is discarded from memory through the CloseSound method.
