Playing audio in the overview bar
To make navigating a file from the overview bar easier, Sound Forge allows you to start audio playback from
the overview bar.
1.
Open the Voiceover.pca file.
2.
Right-click the overview bar. Playback of the file begins from the cursor location.
3.
Right-click the overview bar again. Playback pauses.
4.
Right-click the overview bar once more and immediately left-click at several random positions in the
overview bar. Each time you click the mouse in the overview bar during playback, the cursor jumps to the
new location and playback continues. The feature is useful for quickly navigating a file and locating
general events.
Navigating with the audio event locator
Dragging the mouse within the overview bar initiates playback of small audio loops adjacent to the cursor
position. This is not technically a scrub function, but it serves a similar purpose. It allows you to audition
brief audio segments and quickly locate specific events within a file.
Configuring the audio event locator
1.
From the Options menu, choose Preferences. The Preferences dialog appears.
2.
Click the Other tab.
3.
In the Audio event locator section, edit the Pre-roll and Loop time values as desired and click OK.
Zooming and magnifying
Since there are considerably more samples in a sound file than horizontal points (pixels) on the screen, many
data samples must be represented by each horizontal point when audio data displays in the data window.
Depending upon the editing operation, you may want to view the entire file at once or a small portion of
data in greater detail. For this reason, Sound Forge allows you to utilize two varieties of zooming: time ruler
zooming and level ruler zooming.
The cursor is centered
