Obi is a DAISY/NISO authoring tool that is easy to use, accessible and internationalized. Obi provides a powerful editing environment that supports the structured audio recording paradigm. Obi enables anyone with a minimal amount of training to produce rich yet accessible Digital Talking Books. By empowering mainstream users, Obi brings the benefits of DAISY technology to a broader range of consumers. Although the DAISY reading experience was originally designed for print-disabled users (i.e. blind, visually-impaired, dyslexic, etc.), the technology can benefit mainstream users too. In context where time and cost constraints do not normally allow the production of synchronized multimedia (e.g. classroom environment), Obi can unlock the potential of producers and consumers (e.g. teachers and students).
Obi is free software; it is available at no cost, and its source code is available for anyone to run, modify and redistribute. Obi is released under the LGPL license.
