AIR and Adobe Community Help are not removed when Adobe Audition is uninstalled (issue # 2786975):

Adobe Audition requires the installation of AIR and Adobe Community Help for functionality needed by the application. The main Adobe Audition installer can't remove these additional components. To remove these additional components, uninstall them separately.


Operations that access the temp file cause Adobe Audition to lock-up or crash if the temp location becomes unavailable (issue #2649128):

If the temporary folder location becomes unavailable during Adobe Audition usage, the application either locks-up or crashes. (The location of the temporary folder is specified in the Preferences > Media & Disk Cache section of Adobe Audition's preferences.) This issue can happen is if the user has chosen a network or external drive as their temporary disk cache location, and that location is disconnected. Adobe suggests that users always choose internal drive folders as their temporary disk cache locations and avoid using locations that can commonly become disconnected. If this particular issue happens to you, try the following:

  1. When you relaunch Adobe Audition, do not choose to recover your previous session unless the temp location is now available. If the temp location is not available, the application crashes again when it attempts to find the recovery files in the temp location that is inaccessible.
  2. If the application still does not start, delete the application preferences so Adobe Audition can reset your temp location back to the default, local temp folder.

Export of mixdown when using multiple instances of Full Reverb or Reverb effects cab results in crash in low memory conditions (issue #2780894):

Export mixdown of a session that contains multiple Reverb or Full Reverb effects applied in realtime results in Adobe Audition crashing. This issue occurs in low- or no-free memory conditions. Both Reverb and Full Reverb effects produce warning messages indicating the resource intensity of these two effects. Adobe suggests bouncing tracks containing Reverb or Full Reverb incrementally if session contains multiple clips or tracks with either of these effects applied. Conditions and results vary from system to system depending upon configuration and available and free memory as well as use of these two effects.

Full Reverb and Reverb effects can introduce long delays resulting in changes made in the user interface not being instantly heard (issue #2808053):

Full reverb and reverb effects (being non-real time/high process effects) use a long delay line to produce an audible effect. In extreme situations and settings, this delay can be up to 30 seconds long. Adobe Audition properly delays all audio (via Adobe Audition's built-in delay compensation) so that you hear the affected audio in proper time and context. During playback, any adjustments made to the audio are similarly delayed. Starting or stopping playback flushes the delay line buffer and any changes are audible immediately on next playback. An additional workaround can be achieved by using the new track pre-render feature on any tracks or busses using non-real time, high process effects.

Removing a video clip from a session during playback causes Adobe Audition to hang when playback is stopped (Issue #2835514):

If you choose to delete or remove a video clip while playing a session that contains video, Adobe Audition hangs when playback is stopped. 

Stop playback before removing a video clip from any open sessions.

Opening VOX files using libsndfile generates incorrect waveform (issue #2821203):

VOX files opened in Adobe Audition using libsndfile generates an incorrect (wavy in appearance) waveform. The libsnd version used in Adobe Audition CS5.5 appears to be the source of the bug.

Opening DRM protected AAC files (.m4p) results in crash (issue #2441905):

DRM protected AAC files (.m4p) result in application crash. Adobe has filed a bug with Apple regarding this issue.

Stereo QuickTime .MOV files with QDesign Music 2 Codec do not open (issue #2441868):

QuickTime .MOV file (stereo only) encoded with QDesign Music 2 codec don't open. Adobe has filed a bug with Apple regarding this issue.

QuickTime .MOV files with MPEG Layer-3 audio data do not open (issue #2441853):

QuickTime .MOV file encoded with MPEG Layer-3 audio data don't open. Adobe has filed a bug with Apple regarding this issue.

Third-party Plug-ins

Mac OS only: Cannot use the Audio Unit and VST version of the Slate Digital FG-X effect at the same time. (issue #2796259):

Launching the AU and VST at the same time crashes the application. Launching and using the VST or AU separately works as designed. Adobe suggests choosing to use either the AU or VST version in your projects. The plug-in manufacturer has been made aware of this issue. Check back with them for updates to this particular effect.

Celemony Melodyne editor causes Adobe Audition to crash after adjusting more than two notes within a stereo file (issue #2715030):

Adobe Audition inconsistently hangs when Melodyne plug-in is used to adjust more than two notes in a stereo file. The plug-in manufacturer has been made aware of this issue. Check back with them for updates to this particular effect.

Mac OS only: Certain versions of IK Multimedia plug-ins crash the VST host in Adobe Audition (Mac OS only) (issue #2390403):

IK Multimedia plug-ins crash the VST host in the application (on Mac OS X only). IK has created an updated version of their plug-ins which link against a new Mac OS X C++ library and resolves the issues. Check with IK for updates and the newer version.

Plug-ins that use Pace iLok copy protection can crash on effects scan and launch if the dongle is unplugged from the computer (issue #2756518):

When using plug-ins that require Pace iLok dongle for licensing, crashes occur upon scan or launch of the plug-in. This issue occurs if the iLok is not plugged in to the computer. Ensuring the iLok key is plugged in when scanning or launching the plug-in prevents the crash.

Mac OS only: User interface for BIAS SoundSoap and SoundSoap Pro appears to be unresponsive (issue #2813454):

The user interface for BIAS SoundSoap and SoundSoap Pro plug-ins (on Mac OS X VSTs only) appears unresponsive. This issue occurs because the plug-in isn't sensing proper mouse events after first click. Clicking the Help button in the plug-in returns user interface control and plug-in appears to operate normally after this point. These VST plug-ins operate normally on Windows OS. The Audio Unit versions of the plug-ins also work correctly and are recommended on Mac OS X.  BIAS has been made aware of this issue. Check with them for updates.

Mac OS only: AU plug-ins that use generic Apple AudioUnit User Interface, hang, or crash (issues #2832052 and #2832082):

AU effects relying upon the generic Audio Unit user interface can exhibit various issues that result in hang of the application or unresponsive behavior. When the interface is unresponsive or doesn't open, spacebar triggering of playback and stop doesn't function until the application is restarted. If the effect user interface doesn't open, turn off Preferences > Effects > Open Effects Settings Windows when adding effects to the Effects Rack. Then, relaunch the application.

General Troubleshooting Tips

If the application locks up, crashes, or behaves unexpectedly with commands or features being accessed, try again with a new set of preferences. Although this issue isn't common, if these issues ever arise, allow Adobe Audition to create preferences to see if the problem resolves itself. Here are the steps for Mac OS X and Windows to remove old preferences and create new ones:


1.    Browse to the following location depending on your Operating System:

            Windows XP:C:\Documents and Settings\User_Name\Application Data\Adobe\Adobe Audition\

            Windows Vista and 7:C:\Users\User_Name\Appdata\Roaming\Adobe\Adobe Audition\

2.    Either delete or rename the "4.0" folder (renaming allows you to restore these preferences later if the problem isn't resolved).

3.    Restart Adobe Audition to see if your problem has been resolved.

Mac OS:

1.    Browse to the following location:

           /Users/User_Name/Library/Preferences/Adobe/Adobe Audition/

2.    Either delete or rename the "4.0" folder (renaming allows you to restore these preferences later if the problem isn't resolved).

3.    Browse to the following location:


4.    Delete the file named "com.Adobe.Adobe Audition.4.0.plist"

5.    Restart Adobe Audition to see if your problem has been resolved.
