When working with sound in the Sound Editor, the waveform often displays sound across more than one frame. The ability to zoom makes it easier to keep track of the frame sound on which you are working.
The Sound Editor provides the following zoom modes:
Zoom to Current Frame: Centers the current frame in the waveform with portions of the previous and next frames on either side. The gray slider bar shows the duration of the current frame with respect to the entire sound file.
Zoom to Previous and Next Frame: Displays the entire waveform (previous, current and next frames). The gray slider bar spans the entire waveform.
Zoom to Selection: Displays the selected piece of sound in the waveform. The gray slider bar shows the duration of the selected sound with respect to the entire sound file.
Once a zoom mode is selected, it remains the mode until a different mode is selected. The active mode is indicated with a checkmark in the Zoom menu. Dragging the gray slider changes the zoom and removes the checkmark next to the selected predefined zoom mode.
Note: The Sound Editor toolpane in the Web Page Editor only contains the Zoom to selection mode.
To zoom to the current frame:
From the Zoom menu, click Zoom to Current Frame.
The current frame displays in the middle of the waveform with portions of the previous and next frame on either side.
To zoom to the previous and next frames:
From the Zoom menu, click Zoom to Previous and Next Frame.
The entire previous, current, and next frames display in the waveform.
To zoom to a selected piece of sound:
Left click and drag in the waveform to select the piece of the sound you want zoom.
