Highlights of Obi 4.7 alpha release

Import audio of the section while importing structure from a CSV file

Now you can import audio for the section while creating project using the structure from a CSV file. Obi now accepts the fourth parameter in the fourth column of the CSV, where you can provide the name or full path of the file containing audio of the respective section.

Export To-Do marks as cue markers to WAV file

You can now choose to export ToDo marks from your project to exported WAV files as cue markers for DAISY 3 and DAISY 2.02 standards. The Export dialog has a new checkbox Write TODO timing as cue mark to enable this functionality. Please note that cue marks can be written only in WAV files.

Import audio for Page label while generating speech for pages

You can now import human voice for page labels, while generating speech for page phrases. It is especially useful when audio is being generated for the books in languages other than English. The page numbers, however, will be generated using TTS. The submenu of Generate Speech under the Phrases menu contains commands to execute this functionality.

You can find help on the functionality of these features in the “What’s New?” page of Obi Help, which can be viewed by clicking on the Contents menu item under Help menu of Obi.
