An audio waveform is the graphical representation of audio waves. In Dexster, every audio file that you open, will be loaded into the waveform editor which allows you to view or edit. When you work with the audio waveform, it will be useful to use the Zoom In or Zoom Out features, to help you to make a precise selection on the audio waveform.
In order to zoom in the selected area on the audio waveform, click on the Zoom In button on the toolbar. You may also further zoom in the selection by repeating the same steps.
To zoom out the selected area on the audio waveform, click on the Zoom Out button on the toolbar.
