The overview bar represents the length of the entire file zoomed out to its maximum position. By observing the overview bar, you can determine the following items:
•The section of the audio file currently displayed in the data window.
•The location and size of a selection in relation to the audio file and data window.
•The current cursor location.
Understanding the overview bar
1.Open the Voiceover.pca file and verify that the waveform display is zoomed completely out (1:512 in this case).
Notice that the entire overview bar is dark gray, indicating that the entire file appears in the data window.
2.Place the mouse pointer over the word “Wow,” and click. A small vertical marker, representing the cursor, appears in the overview bar.
3.Create a selection containing the word “Wow.” A shaded block, sized in relation to the size of the selection within the entire audio file, appears in the overview bar.
