The TechAdapt Accessible Media Center (TAMC)

New! A maintenance release for the TechAdapt Accessible Media Center (TAMC) is now available. This release allows TAMC to successfully convert certain invalid NIMAS file sets.

You can find the Windows and Mac versions of TAMC on our downloads page.


This is the home of the TechAdapt Accessible Media Center (TAMC), a software tool that enables and supports the conversion of National Instructional Materials Accessibility Standard (NIMAS) and Digital Accessible Information SYstem (DAISY) file sets into various types of accessible media.

About the TechAdapt Accessible Media Center

TAMC was born out of a need to provide easy and effective conversion options for NIMAS and DAISY file sets. It is intended to allow state and local educational agencies, parents, teachers, and others with access to NIMAS and DAISY file sets with the ability to convert books into consumer-ready formats suitable for use both with and without additional learning support or reading tools.

Currently, TAMC can produce three different file types from NIMAS or DAISY input:

  • Rich Text Format (RTF) files, which can be opened by any of the thousands of applications or hardware devices that understand this file format. RTF has been used in conjunction with screen readers, software magnifiers and other devices for many years, and it remains one of the most widely-used file formats ever. These RTFs can be used in many different ways:
    • with existing braille transcription packages to allow NIMAS or DAISY input to be used in the braille transcription process.
    • as input to audio production tools such as NextUp's TextAloud and NaturalSoft's Natural Reader.
    • with existing hardware devices that can interpret RTF
    • with mobile devices and apps that understand RTF, such as the iPad's Pages app
    • with screen readers and software magnifiers
  • HTML, the popular file format understood by every Web browser. HTML-formatted books produced with TAMC include not only the content of the book, but navigation panes that allow users to easily find information by heading or page number. In addition, the background color and the font color and size of the content can be adjusted for maximum contrast and readability. TAMC's HTML books require only a Web browser to read - no network connection or external software or plugins are required. Samples of the TAMC HTML output using the CAST NIMAS Exemplars can be found in our Samples section.
  • DAISY, the digital talking book standard in use by libraries and educational institutions around the world. DAISY's strong navigation facilities and support for synchronized text and audio, combined with the features of DAISY reader software and hardware, can significantly facilitate the reading process for print-impaired individuals.

In the future, TAMC will be extended to allow the production of other media formats, such as audio and braille. Requests from our clients for other functionality are always welcome.
