Importing, Removing, and Exporting Tempo Information
When you record or bounce an audio file, the current Tempo List is added to the file. You
can then use the saved tempo information for importing or exporting purposes.
In some situations, you may want to import tempo information from an audio file that
was recorded in a different project. The tempo of the selected audio file is used in place
of the project tempo, but only within the borders (start and end points) of that file in the
Arrange area.
To import tempo information from an audio file
µ
Choose Options > Tempo > Import Tempo Information from Audio File in the main menu
bar.
You can also export the current tempo value within the borders (start and end points) of
a selected audio file in the Arrange area. However, you should first remove any tempo
information that exists in the audio file.
