Editing Waveforms:Zooming

You may want to zoom in or out the waveform while working with waveforms. In this section of tutorial, you will learn basic operations on zoom in/out feature in MySoundStudio.

MySoundStudio allows you to zoom in or zoom out the waveform for easier editing work.
You can zoom the waveform in both timeline direction and amplitude direction.

First, let's zoom the waveform in timeline direction.

  1. Open the file me1.wav located in the Tutorial folder.

  2. Place the mouse pointer on the center of the waveform as shown below, and click.
    A flashing cursor appears at the clicked position.



  3. Choose View - Zoom In.
    Notice that waveform is enlarged horizontally (in time direction).

  4. Click (the Zoom In button) on the bottom right of the multi-track window.
    The view of waveform is zoomed in by another increment.
    (The function of View - Zoom In and (the Zoom In button) is the same.)

  5. Press several times until the waveform view changes from line to points.
    The individual points represent a sample, the smallest unit of the waveform data.

    1 sample

  6. Choose View - Zoom Out.
    This time the waveform is reduced by one increment.

  7. Press (the Zoom-Out button) on the bottom left of the multi-track window several times.
    The entire waveform data is displayed in the multi-track window.

You can also use and on the tool bar to zoom in or out the waveform in timeline direction.


Status Bar on the right side of the status bar at the bottom of the multi-track window indicates the current zoom level in timeline direction. For example, x1024 indicates that each pixel on the screen represents 1,024 samples.

Now let's zoom the waveform in the amplitude direction. You will use the file me1.wav again for this lesson.

  1. Choose View - Zoom In Amplitude.
    Notice that the waveform is enlarged vertically.

  2. Click (the Zoom In Amplitude button) on the bottom right of the multi-track window several times.
    The waveform is enlarged further.

  3. Choose View - Zoom Out Amplitude.
    This time the waveform is reduced by one increment.

  4. Click (the Zoom Out Amplitude button) on the bottom right of the multi-track window.
    The waveform is reduced further.

    The waveform with its amplitude zoomed out at maximum.


If you are working with many tracks, zooming a waveform may hide some tracks. In this case, zooming out in amplitude direction helps you view all tracks in the file.


If you need to view the entire waveform in all tracks, hold down the Ctrl key and press F key.
