(Pro Tools HD and Pro Tools with Complete Production Toolkit Only)
Pro Tools HD and Pro Tools with Complete Production Toolkit can automatically apply real-time fade-ins and fade-outs to all clip boundaries in the session on playback. Specify the duration (0 to 10 ms) for automatic real-time fades with the Auto Clip Fade In/Out Length preference in the Operation Preferences page). These fade-ins and fade-outs are performed during playback and do not appear in the Edit window.

The automatic fade-in/out option also has an effect on Voice borrowing in a session. Whenever a lower-priority virtual track “pops thru” a silence in a higher-priority track on the same voice, a fade-in and fade-out is applied to the transition.
This feature is especially useful in post production situations such as dialogue tracking. For example, you can assign both a dialogue track and a “room tone” track with matching background to the same voice. You can then set the AutoFade option to a moderate length (4 ms or so) so that whenever a silence occurs in the dialog, playback switches smoothly to and from the background track without clicks or pops.
Using automatic fade-ins/outs saves you the trouble of editing to zero-crossings or creating numerous rendered fades in order to eliminate clicks or pops in playback. However, those clicks or pops still exist in the underlying sound file. Consequently, those anomalies still appear if the Duplicate AudioSuite plug-in or the Export Clips As Files command (from the Clip List) are used to duplicate multiple clips as a continuous file. To render these real-time auto fades to disk, choose File > Bounce to > Disk.
2 Type a value between 0 and 10 ms for the Clip Auto Fade In/Out Length. A value of zero (the default) means that no auto-fading will occur.
3 Click OK. The AutoFade value is saved with the session, and is automatically applied to all free-standing clip boundaries until you change it.
