Audio Editor-Specific Zoom Options
The Audio Editor offers a few zoom options that are exclusively available in this editor, such as an additional Zoom tool.
The Audio Editor allows for separate zoom level settings for the overview (1) and the main view (2). In the overview, a range indicator on the time ruler indicates which section of the file is displayed in the main view.
You can use the Zoom tool (3) in both the main view and the overview, to zoom in on a detail of the waveform so that it occupies the entire window.
