1 General information
BWC is the best sample editor program available for IBM PC and
compatibles. Only requirements are EGA or EGA-Mono display
adapter and 256kB of memory. BWC supports JDAC (see JDAC.DOC),
Sound Blaster card and the PC internal speaker.
The best result is obtained by a JDAC connected to your stereo
set. You can easily make the JDAC with the instructions included
in this package. It is a simple 8 bit D/A-converter to be
connected to your parallel port. Also a product named Covox
Speech Thing seems to be compatible with the JDAC. It is
possible to use it with BWC.
Sound Blaster's I/O address and IRQ number can be configured
with CFGBWC. The default settings are IRQ 7 and I/O address
0220h (SB 1.5). The internal speaker routine plays the samples
only with 6 bits. It is IBM's fault! Another internal speaker
playing routines, like RealSound, plays the samples just like we
do. But we convert the 8 bit data to 6 bit in real-time to get
the best result. Note that you can easily hang your computer by
playing samples with too high digirates.
BWC supports MSMOUSE-compatible mouse. Remember to load your
driver before starting BWC.
BWC identifies automatically following sample formats: RAW, IFF,
RealSound (Steve), Sound Blaster's (Voxkit) format, Akai
Professional Sampling Keyboard (see part 4 of this document) and
of course our own format.
Don't panic if you find some undocumented features in BWC. Just
report them to us and they will be mentioned in the future
versions.
2 Commands
2.1 Command line parameters
Usage of BWC is following:
BWC [filename] {filename2} {/I | /1 | /2 | /3 | /4 | /S} {/M}
{/P{hz}} {/Vvol}
Filenames are the name(s) of the sample(s) you want to load in
the startup. You must specify one, the other is optional. You
can specify full pathname, or just the name. See Defaul Dir
setting in Setup for more information.
"/I", "/1".."/4" and "/S" are the output device used. This
overrides the Setup setting.
/I = Internal Speaker
/1 = JDAC (or other D/A-convertor) in LPT1
/2 = JDAC (or other D/A-convertor) in LPT2
/3 = JDAC (or other D/A-convertor) in LPT3
/4 = JDAC (or other D/A-convertor) in LPT4
/S = Sound Blaster
"/M" must be given if you are working on EGA-Mono display. The
default setting is EGA-Color. BWC does not automatically detect
your screen type.
With "/V" you can give start-up volume for sample-player or
editor. Default is 100%.
When "/P" is given BWC just plays the sample and exit. So BWC
can also be used as a sample-player. You can specify the playing
rate by writing it right after "/P". No spaces or other
characters. Just like "/P22000". This parameter replaces the
value detected in load.
2.2 Commands in editor
After the sample(s) are loaded the main screen will appear. The
upper area is the first sample in graphical type. There is also
the sample's infoline. Below it are the same things for the
other sample. Below them there is general information about
memory, editing, buffers, markings, volume and zoom. And in the
bottom of the screen is the menu of available commands.
2.2.1 Infolines
The sample's infoline is:
??? Size: ??????B Lenght:???????s Digirate:?????Hz Type:????
And the general info is:
Editing: ????? Marked: ??????B, ???????s Volume: ???
Free mem: ??????B Buffer: ??????B, ???????s Zoom: ?????
In sample's infoline the first word tells you the name of the
sample. DOS's limits are used, 12 character name and 3 character
extension. Size lets you know about the size of the sample as
bytes. Lenght does the same, though informing it as seconds. You
can see the digirate of the sample after word Digirate. It is
showed as hertzs. Type shows the type of the sample. It is
processed as bits. Here is the list of available types:
0000 = RAW sample, loops off.
0001 = RAW sample, loops on.
0080 = IFF sample, loops off.
0081 = IFF sample, loops on.
In general info editing tells the sample you are editing. Is it
"Upper", "Lower" or "Both". Marked shows the size of the area
marked with the mark lines in bytes and seconds. If the mark
lines are off, the size is zero. The volume shows the percental
volume rate of playing. It is handled real-time, so you can test
which would be the best volume. Free mem informs about the
available memory. You can't process with bigger sample than you
have free memory. Buffer tells you the size of the copy buffer
in bytes and seconds. If you have Both-function On, the buffer
functions are directed to the both samples, upper and lower.
Therefore the number of free memory for buffer must be bigger
than marked area. Zoom lets you know the ratio of the zoomed
area. If it is "2", the ratio is 1:2, one byte in screen means
two bytes in memory.
2.2.2 Menus, keys
To move between the upper or lower samples press the spacebar
key. Also if you are in Both mode, press the spacebar to set it
off.
You can choose the desired function in the command line by
pressing the button which is lighted in the command word. By
using ESC the program returns to the main menu. You can also use
F1-F9 to jump directly between the menus.
If you try to do some uncomfortable command suggestions to the
program or there are not enough memory available, BWC will
answer to you by saying BEEP.
File menu:
Save: Save saves the sample to the disk and asks the new name
of the sample. The default is the original name. If you
don't change the name the original sample will be
replaced. The sample will be saved to our own format.
There are not any possibilities to save the sample in
some other format in BWC 1.06. When you have saved the
sample, the new name of the sample will replace the
original sample name in the sample's infoline.
Load: Loads sample from disk to the memory. A little window
appears to screen. Write the desired sample path and
name to load the sample. You can also specify the sub
directory for the samples in Setup, and when loading
something, you don't have to give it again, you just
choose the sample. The sample always will be loaded to
lower sample. Copy buffer will also be cleared.
Exit: By the funct
