Refreshabraille 18(Formally Refreshable Braille Display)(Continued) 
Purpose To produce a high quality, portable, inexpensive refreshable braille display and input device that may be used with the Braille+ or with other portable or stationary devices. Project Staff Larry Skutchan, Project Leader Thomas Friehoff, Project Consultant Rob Meredith, Programmer Rosanne Hoffman, Editor Terri Gilmore, Artist Background As APH advances its braille interests to all parts of the company, technology applications for braille were also prominent. A high quality integrated refreshable braille subsystem was finalized and released for the Braille+, and a new display and input device, Refreshabraille 18, was designed, debugged, and released. While the refreshable braille display matches Braille+ in size, convenience, and durability, it was designed to be used with a variety of other devices, both portable and desktop. GW Micro's Window-Eyes screen reader and Apple's VoiceOver screen reader both contain built-in support for Refreshabraille18, and it can be used with other software that does not yet know about it by telling that software that the device is a display from Baum. APH ships a driver that adds support to an existing JAWS installation. Refreshabraille was designed with both USB and Bluetooth (wireless) connections, and the firmware keeps device configuration simple by automatically detecting requests for a connection through either interface. Input capabilities mean the user can control her PC or other portable device like a personal data assistant (PDA) or smart phone from the braille display. When these input features are combined with the Bluetooth wireless communications, it is possible to keep the PDA away in a purse or pocket and use Refreshabraille to both read and control the device. This small, elegant braille control is ideal for both students and professionals who prefer or require braille. Refreshabraille is easily configurable with respect to its orientation. In other words, the user may use the device with the braille cells either on the side closest to her or on the side furthest away. All controls also flip their orientation when the orientation of the braille cells is altered. Work during FY 2009

Studio Recorder(Continued) Purpose To produce a simple-to-use, robust digital audio recording tool geared toward spoken word content. Project Staff Larry Skutchan, Project Leader Rob Meredith, Programmer Steve Mullins, Special Projects Manager John Zinninger, Senior Technician Dave McGee, Manufacturing Specialist Rosanne Hoffmann, Research/Project Assistant
Studio Recorder is a powerful digital recording and editing software package geared to make recordings of the spoken word. It includes features not found in audio recording and editing programs primarily designed for music production. Such features include: 1. Speed up playback with no pitch distortion 2. Three levels of phrase detection 3. Index tone generation and removal 4. Instant open on large files 5. Instant cut, copy, paste, and delete 6. Intercom functionality 7. Simple user interface 8. Accessibility for blind and visually impaired users 9. Multiple user marks and notes 10. External controller support Studio Recorder was originally written for internal use at APH to serve as a tool for creating digital audio recordings for the National Library Service (NLS). It contains many features that ease the task of recording, editing, and proofreading audio books. Its features also facilitate simple production to Digital Talking Book or to cassette. While Studio Recorder was originally written for use by the professional narrator and narration monitor, its simple operation makes it ideal for nearly anyone interested in recording, editing, and producing spoken word audio documents in an efficient manner. In addition to all of the benefits of digital recording and playback technology common to digital recording software, Studio Recorder provides unique capabilities geared to both spoken word content and, more specifically, recordings intended for distribution via Digital Talking Book, on audio cassette, or via the World Wide Web. Features such as the intercom mode allow recording professionals, who often collaborate from separate booths, to communicate through the PC's speakers and sound card. Other features, such as the ability to mark and label points in the recording, make it easy for narrators working on large works to preserve notes about pronunciation and characterization, allowing quick reference to information from past recording sessions. The phrase detection capabilities streamline the process of sifting through cumbersome audio files. Instead of using time as the criterion for navigation, these features let the narrator use content for maneuvering through the audio file in a manner similar to that of moving through text in a word processing program. Studio Recorder also provides advanced capabilities such as punch in/out recording, linear fade, instantaneous editing, and time-specific alarm tones that assist the user in various common audio editing and management tasks. Continuing development is largely driven by studio needs and customer requests. An outstanding response to this input has defined a software package that is robust, flexible, and enjoys thousands of hours of use each year at APH alone. As development continues, Studio Recorder becomes a more integral tool in the Digital Talking Book creation process. Work during FY 2009 The following enhancements were made to Studio Recorder: Version 3.7.X, June 2009
Version 3.7.1, April 2009
Version 3.7, February 2009
