You can do this by selecting the file and opening the Elastic Properties window (shortcut, Clip menu, or right-click), and typing in the correct original Tempo in the appropriate field (see Fig 4).
If you know the original Tempo of the audio, you can simply tell Pro Tools what it is, and this should correct any miscalculations, allowing Elastic Audio to conform the file properly to the current Tempo.
When this happens, you'll have to deal with it manually. But if the audio file is an uneven number of bars long, or the original tempo of the audio is not steady, then Pro Tools may miscalculate the original tempo, and when it Elasticizes the audio to match the current Tempo, the timing will be off-anywhere from a slight drift to an obvious mismatch! If the audio you're bringing in is in a standard loop format (like REX or ACID), or the file has been trimmed to be an exact number of bars (say, 8 bars exactly, as opposed to 8 bars and 1 (extra) beat), then there should be no problems. This can happen if Pro Tools has difficulty determining the original Tempo of the audio file, which it needs to do in the background, while conforming and importing. Sometimes, even if you import audio correctly, as outlined above, and Pro Tools creates an Elasticized clip for you, as advertised, the audio may still not line up perfectly with the Session Tempo. Tempo Issuesīut I mentioned a caveat earlier. So when Tempo-matching is required, the Workspace or Drag and Drop methods are preferable.
The same is true when you bring in audio via File > Import > Session Data. However, if you import audio from the Import command (File > Import >Audio.), no Tempo matching or Elasticizing will be done, and you'll have to do it by hand after the file's been brought in. Just as in the Workspace window, if you drag and drop to blank space in the Edit window, Pro Tools creates a new Elastic-Audio-enabled track for you if you drag into the Clip List, you'll have to add your own track for the new audio, and enable Elastic Audio on it yourself-but either way, the end result is the same.īy default, this Preference is set to “REX and ACID Files Only”, which means that only files in either of those standard loop formats will be conformed to the Session Tempo, but if you switch to “All Files”, then you can conform. Another Preference in the same pane, “Elastic Audio > Default Plug-In” determines which Elastic Audio algorithm is used for this-the default is Polyphonic, which works on all kinds of audio (including rhythmic and monophonic tracks). If this option is enabled, it means that when dragging and dropping audio files into a Session, Pro Tools will not only bring in the original file, but also create an Elasticized version (clip) of it, ready to play at the current Session Tempo-you'll see both in the Clips List. This approach works best with loops, but it can be used with any audio, though with caveats (see below).įig 3 The “Drag and Drop from Desktop Conforms to Session Tempo” preference. But if you enable the Elastic Audio button (just to the right), then Pro Tools will audition all audio files instead at the current Session Tempo, making it much easier to determine if a particular bit of audio will work well in the session you're about to import it into.īut the really convenient part is that, once you've selected a file to import, you can drag it into the blank area in the Edit window (below the last track), and Pro Tools will create a new track with Elastic Audio (and Ticks mode) already enabled, so the file should be ready to play at the current Tempo, in sync with the Session. Once you've located the audio file(s) you want (let's say, drum beats), you can turn on the Preview button, and as you select different audio files, Pro Tools will play them-as is, at the original tempo. This window is a browser, much the same as the (Mac) Finder, but it makes easier work of auditioning and importing audio files.
