You can choose to apply phrase detection on these audio files from check box Apply phrase detection while creating a project by importing a CSV file from Project tab of Preferences dialog. In addition, you can provide metadata in the file named “metadata.csv” and store it in the same location as the CSV. Metadata will also be imported during the import.
