Application of real-time streaming audio to Web-based courses Thomas I. M. Ho, Brian Ho WebLab Indiana University Purdue University Indianapolis

Abstract A year of experience with the application of real-time streaming audio (RealAudio) to Web- based courses has yielded a wealth of experience in synchronous delivery of live instructional content and asynchronous delivery of archived content. Outcomes include:

1. Live broadcast of lectures 2. Archived lectures with the soundtrack synchronized with the Web pages displayed during the live lecture (Synchronized Multimedia) 3. Voice annotations of Web page links including: a. Explanation of examination questions and answers b. Motivational messages to explain Web pages c. Oral instructions for assignments

Products of this experimentation include:

1. User interfaces for: a. live broadcast b. archived lectures 2. Productivity tools for: a. constructing Synchronized Multimedia content b. creating voice annotations

What is RealAudio?

The RealAudio Server, RealAudio Encoder, and RealAudio Player comprise the RealAudio System created by RealNetworks (1997). The RealAudio Server streams files created with the RealAudio Encoder to free RealAudio Players on sound card-equipped personal computers, which continuously decompress the audio and play it in real time without download delays, even over 14.4 Kbps modems.
