57 ADOBE AUDITION 1.5
User Guide
Auto Zero-Cross Edits Automatically adjusts the beginning and end points of all Cut,
Copy, and Paste-type edits to the nearest place where the waveform crosses the center line
(zero amplitude point).
If the amplitudes aren’t lined up on both sides of the selection, the endpoints are at
different amplitudes. This often results in an audible pop or click at that point.
Smooth Auto-Scrolling During Playback Enables smooth scrolling when playing back
audio in Multitrack View. By default Adobe Audition uses a paging method of scrolling in
Multitrack View instead of the smooth scrolling technique used in Edit View. This saves
on system resources.
Save Locked Track Files After Closing Sessions Saves the temporary files associated with
locked tracks. When you reopen the session, Adobe Audition uses the temporary file
instead of mixing down the locked tracks.
SMTPE options
The SMTPE tab in the Settings dialog box provides options for adjusting the settings for
incoming SMTPE timecode. For more information, see “Setting up for SMPTE synchro-
nization” on page 40.
Managing temporary files
When you edit a file, Adobe Audition converts the audio data into an internal, temporary
waveform. This process allows for quicker editing, better handling of large files, and the
ability to undo changes. You can specify the folders where you want Adobe Audition to
save temporary files and customize Undo options in the System tab of the Settings dialog
box. (See “Setting Adobe Audition preferences” on page 43.)
One advantage to using temporary files is virtually unlimited waveform sizes, since the
maximum waveform size depends only on the size of your hard drive. The drawback, of
course, is that the temporary file can get extremely large, potentially preventing you from
being able to save a masterpiece on the same drive. If you notice long delays between edits
or stuttering sounds on playback, you may be running out of free disk space in which to
save the temporary file. In this case, you can use the Manage Temporary Folder Reserve
Space dialog box to delete temporary files you’re not using, clear specific Undo items, and
change the amount of reserve space. This dialog box automatically appears when available
hard drive space nears zero kilobytes.
