Dolphin Publisher offers organisations and individuals a reliable, efficient production tool for text and audio-based publications.

Support for EPUB 3 media overlays was added previously, as far back as 2014, and this version 4.02 contains a series of improvements that meet the latest EPUB 3.2 standard from W3C, including EPUB Accessibility 1.0.

New in Dolphin Publisher 4.0

This update includes a host of new features and improvements. These help users meet accessibility guidelines and simplify the production of audio books. Dolphin Publisher is now easier to install and training manuals are available to guide users through.

    An adjustment has been made so a draft publication can be sent to EasyReader for review.
  • Audio file import
    The buffer has been enlarged to increase the number of audio files that can be imported through the File Open dialog.

    The original file name is now used as the heading name when audio files are imported.

Changes made to Dolphin Publisher 4.0

Certain legacy features which were available in previous versions are no longer in use.
These have been removed in the latest version of Dolphin Publisher. Many of these were dependent on features inside Internet Explorer, which Microsoft no longer supports.
Please note that IE is still used to render HTML pages.

Features removed in Publisher 4

  • HTML Editor
    This feature was heavily dependent on Internet Explorer and caused a majority of the Dolphin Publisher support incidents.
    HTML documents now need to be prepared in advance or editing must be done outside Dolphin Publisher.

  • External HTML Editor
    This feature was heavily dependent on Internet Explorer and caused a majority of the Dolphin Publisher support incidents.
    HTML documents now need to be prepared in advance or editing must be done outside Dolphin Publisher.

  • Digital I/O
    This feature was a unique customisation for a specific customer and has now been removed.
  • Remote Control RE-11
    This device is connected to the computer via a COM port, which no longer exists on modern devices.  
  • Multi-Volume Support
    This feature targeted CD distribution only and has been removed.
  • PDTB v2
    The support for encrypting the content into PDTB v2 has been removed as it is no longer used.
  • EasyReader Express
    This has been removed as it was a feature that targeted CD distribution only.
  • Build to other character encoding
    This feature existed because some old DAISY hardware players were not compatible with UTF-8.
    This is not an issue with today’s devices.
