- INTRODUCTION
- ============
-
- In the past few years, the computer world has been gaining interest
- in computer-generated speech and sound. In this area, the Apple Macintosh
- and Commodore Amiga provide built-in sound control so that their machines can
- play digitized recordings with little effort from the programmer. IBM,
- however, has chosen not to include advanced sound capabilities in its line of
- personal computers. The market has shown that relatively few people will buy
- speech or sound add-ons from either IBM or third parties. Until such
- hardware is standardized, speech software will encounter great difficulty
- in gaining acceptance. In this regard, however, mathematics, engineering,
- and software can come to the rescue: it is possible for a PC to play good
- quality sound without additional hardware.
- Over the years, several attempts have been made to play digitized
- sound on PCs without additonal hardware. Many have appeared in the public
- domain, but few are coherent. Commercial software has had greater success,
- but most of these programs produce rough speech. With the recent rise of
- interest in multimedia, some developers have produced good quality sound.
- This Raiders Demo rivals that of the best public domain and
- commercial successes.

- USAGE
- =====
-
- To run the program, type the filename (omitting the extension) at the
- command prompt. There are no command-line switches.
-
- In addition, the sound files (*.SND) may be used with other programs
- that play digitized sound.
-
- LIMITATIONS
- ===========
-
- You must have an 80286 or better processor in your PC.
-
- Your computer system must have enough available RAM to load the sound files.
-
- This demo relies on the system timer interrupt, so any other interrupt-
- driven software may conflict with it. Pressing keys, moving the mouse, etc.
- will put a buzz in the output. The program will not give proper results if
- the DOS 4.0 DOSShell has been run or if it is run in a DOS box under OS/2 or
- Windows; however, it runs well under the DOS 5.0 DOSShell.
-
- CONCLUSION
- ==========
-
- This demo uses a special version of a general-purpose digitized
- sound player that runs on all PCs. If you are interested in
- a complete package of sound programs, write for more information.
- A Star Trek audio demo program is also available.
-
- Richard E. Zobell wrote the file-loading routine.
