Detailed Description
A waveform component to display the content of a pooled AudioSampleBuffer.
Features:
- draggable SampleArea which can define the range of used samples.
- drag and drop of pooled samples of files (only .wav)
- right click to open a file dialog to load a .wav file
- playback position display
- designed to interact with AudioSampleProcessor & AudioSampleBufferPool

inlineoverridevirtual |
Returns only 44100.0 (this will have no impact, but must be overriden.
Implements AudioDisplayComponent.
| void setAudioSampleBuffer | ( | const AudioSampleBuffer * | b, |
| const String & | fileName, | ||
| NotificationType | notifyListeners | ||
| ) |
Call this when you want the component to display the content of the given AudioSampleBuffer.
It repaints the waveform, resets the range and calls rangeChanged for all registered AreaListeners.
| void setRange | ( | Range< int > | newRange | ) |
Call this whenever you need to set the range from outside.
