Certain Audio Files Cannot Be Calculated or Cleared of Elastic Analysis in Workspace Browser (PTSW-29622)
There are some rare cases where a file will have a file suffix of a file format supported by Elastic Audio (either .WAV or .AIF), but
the Pro Tools Workspace Browser will not allow calculation or clearing of elastic analysis. The browser menu items Calculate
Elastic Analysis and Clear Elastic Analysis will be greyed out. In these cases, the file may actually be in a non-supported format.
To check the file’s format, look at the Format column in the Workspace browser. If a file format other than WAV or AIFF is shown
(such as QuickTime), then the file cannot be calculated or cleared of elastic analysis. Note that these non-supported files can still
be previewed in tempo, as well as elasticized once imported into a session.
Tempo Maps Made from Bar|Beat Marker Generation in Beat Detective Cause Clip Groups in Rendered Mode to Fall Offline
(PTSW-34950)
A tempo map made from Bar|Beat Marker Generation in Beat Detective will cause clip groups in Rendered mode to fall offline.
The workaround is to make an edit to the offline clip and then toggle the Elastic Audio from rendered to real-time and then back
to rendered.
Maintaining Phase Coherency with Elastic Audio Pitch Processing (PTSW-20602)
When there is Elastic Audio Pitch processing enabled on a track, switching from Polyphonic, Rhythmic, or X-Form to Mono-
phonic or Varispeed can disrupt phase coherency. To preserve phase coherency in this case, be sure to clear all Elastic Audio Pitch
processing from the track before switching to the Monophonic or Varispeed algorithm.
Drift in an Audio File May Occur when Using Elastic Audio and the Monophonic or X-Form Algorithms (PTSW-33768)
Drift in an audio clip may occur when using elastic audio depending on how much the clips is expanded or compressed when us-
ing the Monophonic or X-Form algorithms. If you are using elastic audio with material that contains transient information in it
that you would like to keep from drifting, you should use the Polyphonic or Rhythmic algorithms.
Default Input Gain Preference Is Only for Elastic Audio Imported at Session Tempo (PTSW-34096)
The Default Input Gain preference in the Elastic Audio section of the Processing Preferences page is for Elastic Audio Imported
at Session Tempo only. This preference option will not function unless Preview in Context is enabled in Workspace, and/or “Drag
and Drop from Desktop Conforms To Session Tempo” is enabled in the Processing Preferences page.
Displayed Timebase is Incorrect after Importing Elastic Audio Tracks (PTSW-46897)
The incorrect timebase is displayed after importing Elastic Audio tracks to existing tracks with opposite timebase. You will need
to manually select the correct timebase for the affected tracks.
Elastic Audio Clips on Playlist Lanes Are Not Rendered (PTSW-47311)
In Playlists View, any Elastic Audio clips on Playlist lanes are not rendered (waveform is “off-line”) when changing the track’s
Elastic Audio processing from Real-Time to Rendered.
Clip Groups Containing Elastic Audio Are Not Recognized as Elastic if the Clip Group Itself Has Not Had Any Elastic Functions
Applied (PTSW-34335)
If a clip group contains Elastic Audio inside it, but no Elastic Audio operations have been performed on the outermost level of the
clip group itself, then the clip group will not register as Elastic Audio. When used to create a new track, the track will not auto-
matically be Elastic Audio–enabled, and the elastic audio inside the clip group will be rendered using the default Elastic Audio
plug-in for the session. As a workaround, add a warp marker to the clip group to force it to register as an elastic clip. Or, create
an Elastic Audio–enabled track first, then add the clip group to it.
Cannot Import Elastic Audio Tracks with the Consolidate From Source Media Option (PTSW-33894)
Use Copy from Source Media to import Elastic Audio tracks.
Timing Inaccuracy in Audio Files Converted from CAF and MP3 with Preview In Context Enabled (PTSW-46707)
Audio files converted from CAF and MP3 with Preview In Context enabled can cause timing inaccuracies (gaps in the audio and
inner-clip asynchronous transients issues). This is inherent with compressed file formats.
