-
- WAIVER:
-
- REplay is offered to you as a demo for evaluation. REplay is
- offered AS IS and absolutly NO guarantees are given or implied as
- to its suitability. The author assumes no responsibility for any
- damage to your machine or loss of data incurred while using this
- program.
-
-
- UPDATE INFO:
-
- This is the first update to REplay version 1.00. I found a
- bug involving the keyboard, if it was hit during a playback it
- would cause the computer to go off into 'WONDERLAND', I forgot to
- disable the keyboard interrupt (OOPS!!). This has been corrected.
- Also I changed the command line entry and added a switch, see the
- section titled RUNNING REplay for more info.
-
- GENERAL:
-
- Thank - you for showing interest in REplay 1.00. REplay will
- play back 8bit digital sampled audio files on the internal
- speaker of the PC/XT/AT and compatibles. This program was written
- in an attempt to produce better quality audio on the internal
- speaker. This particular version is mainly a demo program to test
- out the method I came up with, however, since it does appear to
- work quite well, I will continue work on it to develop a TSR
- version for every day use, as well as a linkable OBJ version to
- add better audio to games and other programs.
-
- The original archived file contains the following:
-
- REPLAY.EXE - The executable file
- GOODMORN - A sample audio file (type 1)
- HAL - Another sample audio file (type 1)
- GREETING - Another sample audio file (type 2)
- REPLAY.DOC - This text file
- ORDERF.ORM - An order form for the source code
-
- Please feel free to distribute this program, on the
- conditions that, only the original archive file containing the
- above files be distributed, and, the executable file is not
- altered in any way, and, no fee is to be charged to the person
- or persons receiving it.
-
- RUNNING REplay:
-
- To invoke REplay simply enter:
-
- REPLAY [-Fx][-Sy] <DATAFILE>
-
- - where x is a file type of:
-
- 1 - TYPE 1 <DEFAULT>
- 2 - TYPE 2
- - without going into great detail on
- each of these two types, suffice it
- to say that if it sounds bad on type 1
- try type 2. (with these two types you
- should be able to play most of the
- digital audio files created for the
- Atari ST).
-
- - and y is a number from 0 - 6 selecting one of the
- following replay rates:
-
- 0 - 11.5 Khz
- 1 - 12.5 Khz
- 2 - 14.0 Khz
- 3 - 16.0 Khz
- 4 - 18.5 Khz
- 5 - 22.0 Khz
- 6 - 27.0 Khz
-
- (the above frequencies are approximate).
-
- - and <datafile> is the complete path, filename, and
- extension of the digital audio data file.
-
- EXAMPLE: REPLAY -F2 -S3 GREETING
-
-
- ABOUT THE DATA FILES:
-
- The particular data files contained in the demo were taken
- from an Atari ST, and work quite well. I suspect that any 8bit
- digital sampled audio file will work. (some files use a
- compression scheme that I have not figured out yet, and these
- files will only produce a lot of noise).
-
- COMPATABILITY:
-
- I developed REplay on an AT laptop machine, and can tell you
- that the audio quality from the small piezo-electric speaker it
- has was, to say the least, BAD!!. However, I tested it on a few
- full size machines (XT and AT), with real speakers, and it worked
- great. I should also mention that REplay temporarily grabs the
- timer-tick interrupt, and therefore will throw out your DOS clock
- by a few seconds each time it is run. This is not fatal though
- becuase the next time you boot your machine the DOS clock will be
- re-initialized anyway. (If for some reason you cannot live with
- your clock being a few seconds slow, simply use the DOS TIME
- command to reset it).
-
- FUTURE OF REplay:
-
- As I stated earlier, I am still working on new versions of
- the program, and will make them available to you as they are
- ready. I am also currently working on a hardware project and
- software package, to allow you to record your own digital audio
- using the parallel port.
-
- REQUEST FOR INPUT:
-
- I am very interested in what you think of REplay and request
- that if you have any questions, comments, suggestions, or
- criticism, you can reach me on GEnie at mail address R.ZOBELL, or
- you can write to me at the address listed at the end of this text
- file.
-
- GETTING THE SOURCE CODE:
-
- If you are interested in learning more about how REplay
- works, for a generous donation of $15.00, I will be happy to send
- you a copy of the source code, commented and documented, as well
- as a complete technical explanation of how the audio is
- recovered. To obtain this, simply print the file ORDERF.ORM to
- your printer, fill it in, include a cheque or money order (do not
- send cash by mail!) for $15.00 and send it to:
