- WAVEFORM 1.0
-
- Written by : Mark R. Johnson
- Produced by: City Zoo, Inc.
-
-
- Waveform is a demonstration waveform editor written to make use
- of the Sound Blaster utility programs VPLAY and VREC. With Waveform and
- these other two utiliies, one can digitize, play, view, and manipulate
- sound waveforms. Even without a Sound Blaster or the utilities, one can
- edit sound files. Version 1.0 has many of the more advanced functions
- turned off. These functions are available in version 1.1 of the program.
- See Registration below. Waveform 1.0 and 1.1 are NOT in the Public Domain.
- Version 1.0 can, however, be freely distributed in an unmodified form as
- long as this documentation file remains with Waveform. Version 1.1, however,
- may NOT be freely distributed.
-
-
- REQUIREMENTS:
- ------------
- Sound Blaster Card
- Sound Blaster Utilities VPLAY.EXE and VREC.EXE
- 640KB RAM Memory
- CGA, EGA, VGA, or Hercules Video
- Microsoft or Compatible Mouse (optional)
-
-
- REGISTRATION:
- ------------
-
- Waveform 1.0 is a demonstration program. A registration fee of
- $50 (US) will entitle you to a copy of Waveform 1.1, which makes use of
- the following options that are turned off in version 1.0:
-
- Add Waveforms: Averages together two waveforms - the clipboard
- and the current waveform.
-
- Create Echo: Allows the user to select a section of a waveform
- and create an echo from it.
-
- Resample Waveform: Resamples a waveform to a different rate such
- that the result sounds approximately the same
- at a different sample rate.
-
- Volume Flange: Allows the user to change the volume of sections
- of a waveform, either sweeping louder or softer,
- or simply amplifying equally across the selected
- section.
-

-
- FUTURE VERSIONS:
- ---------------
-
- Future version of Waveform will include:
-
- * More functions for manipulating sound waveforms
-
- * Extensive support for Creative Voice File headers and data packing
-
- * Access to larger sample sizes (greater than 65,000 data points) and
- extended or expanded memory.
-
- * Direct access to the Sound Blaster Card's capabilities including
- playing and recording of sound files.

- USAGE OF WAVEFORM:
- -----------------
-
- Waveform is a graphical menu-driven waveform editor that gives
- the user the ability to manipulate sound waveforms. In most functions,
- operation is more or less intuitive. The mouse or keyboard is used to
- highlight sections of the current waveform through the use of the two
- drag bars. There are, however, a few unique qualities that need to be
- explained:
-
- (1) Waveform makes use of the Sound Blaster utilities VPLAY.EXE and
- VREC.EXE to play and record the sound files. To find these files,
- Waveform searches for the SOUND environment variable. This variable
- should in the AUTOEXEC.BAT file be set to the Sound Blaster
- subdirectory. The program actually looks into the VOXKIT\ subdirectory
- of the Sound Blaster subdirectory. For example, if the main Sound
- Blaster files are in the directory C:\SB and the files VPLAY.EXE and
- VREC.EXE are in the directory C:\SB\UTILITY then there should be a
- statement in the AUTOEXEC.BAT file as follows:
-
- SET SOUND = C:\SB
-
- This will allow Waveform to find the files it needs in C:\SB\VOXKIT.
-
- (2) A section can be highlight before or after the function to be
- performed has been selected. However, if a section is highlighted
- with the selection bars and PLAY is selected, only that section
- that is highlighted will be played. The selection bars can be
- removed by simply hitting ESC.
-
- (3) In the EDIT sub-menu, there is an option called SELECT. This allows
- the user to use the KEYBOARD to select a section of the waveform to
- either play or perform one of the functions. This option need not
- be selected to use the mouse to highlight a region. To use the mouse,
- just point, click, and drag.
-
- (4) Waveform does not yet fully support the Creative File Voice files.
- Among the options not supported are data packing, repeat loops, and
- markers. However, many of these files that are not directly supported
- may be imported as raw data and modified to reproduce the original
- sound.
