The WaveformScroller object, accessible through the control's WaveformScroller property, is internally implemented as a COM interface called IWaveformScroller and contains information needed to render a waveform that will scroll during playback.

 

It can be used at Run-time in order to create a waveform scroller and to change its graphical settings. For details about using waveform scrollers refer to the How to scroll the sound's waveform during playback tutorial.
