Chapter 4. Managing Audio Files > Using Temporary Files

Using Temporary Files

Whenever you work with audio files, you almost always make changes to them. Trimming, fading, normalizing, overdubbing, adding effects—all change the audio file that's open in Audition.

To facilitate and speed up editing (and to help make your edits reversible), Audition creates a temporary copy of the file during the editing process. The names of these temporary files begin with CEP, and they have the .tmp file extension.

None of us has infinite hard-disk space, and temporary Audition files can be surprisingly large. So you should check to see where Audition is keeping your temporary files, particularly if your computer has a partitioned hard drive (in that case, you should make sure the folder resides on the drive with the most available disk space and/or the highest speed).

To specify folders for storing temporary files

Choose Options > Settings (F4) (Figure 4.6).

Figure 4.6. Choose Options > Settings to specify a folder to house your temporary (.tmp) files.

In the Settings window that opens (Figure 4.7), click the System tab.

Figure 4.7. The System tab in the Settings dialog.

In the Temporary Folders area, note the default Temp folder that Audition has chosen for you, or specify a different folder in the Temp Folder field (Figure 4.8). Make sure the selected Temp folder is on a drive with plenty of free disk space.

Figure 4.8. You can accept the default folder in the Temporary Folders field or specify your own choice.

In the Reserve field, accept the default or specify a different value (in megabytes).

This value sets the amount of space in the Temp folder; set a value high enough so that you don't run out of space in the folder.

Click OK.

Audition applies the new values and returns you to the Edit or Multitrack view.

✓ Tip

  • Specify a high Reserve value for your Temp folder if you plan to work with large numbers of files at once (say, in a multitrack session). In a case like that, determine the amount of free disk space available, and choose the highest Reserve value that seems feasible.

  • Optionally, you can specify a second temporary storage folder in the Secondary Temp field. If you have a large amount of free space on the hard drive that houses your main Temp folder, it's usually not necessary to specify a second one.

Manually Deleting Temporary Files

Unless Audition is running, your temporary file folders should be empty. Audition automatically deletes all temporary files when you close a session. However, if either Audition or your computer crashes and therefore fails to close properly, unwanted (and often large) temporary files may be left behind.

If Audition is not running, you can simply browse to the Temp folder in Windows and delete the files. You can also get rid of existing temporary files from within Audition itself.

To delete temporary files within Audition

Choose File > Manage Temporary Folder Reserve Space (Figure 4.9).

Figure 4.9. To clear your temporary files while Audition is running, choose File > Manage Temporary Folder Reserve Space.

In the window that appears (Figure 4.10), select the file in the Waveform list that you want to close.

Figure 4.10. Select the waveforms you want to delete and click Close File.

Click Close File.

Audition deletes the temporary file.

✓ Tips

  • You can also remove Undo tasks that have accumulated for a file. When you select a file in the Waveform list, a list of Undo tasks appears in the window next to it. You can select any Undo task and click Clear Undo(s).

  • You can change your reserve settings in the Manage Temporary Folder Reserve Space window by setting a new value in megabytes and clicking Set New Reserves.

  • Normally, Audition creates a temporary file only when you've edited a file. To force the program to create a temporary file at any time (if, for example, you're especially concerned that the complex edit you just made be recorded somewhere immediately, but you're not ready to save the file), choose File > Flush Virtual File.
