OVERVIEW
Z Blaster Raw Kit is another addition to the Z Blaster digital
sound series for C128 CP/M mode. Now you can play any four bit
uncompressed sound file (.RAW, etc)! A handy conversion utility is
included to convert any eight bit uncompressed sound file (.SND,
etc.) to a four bit uncompressed sound file.
REQUIREMENTS
A C128 or C128D running CP/M 3.0, ZP/M 3 or compatible OS.
Sound output through monitor speaker or better quality sound
amplification system.
Z BLASTER RAW PLAYER
ZBRAW.COM enables you to play any uncompressed four bit file
through the C128's SID chip. To play a file:
ZBRAW {U:D:filespec} hertz {sn}
(U:D:) is any valid CP/M user and drive, (filespec) is any valid
CP/M file name, hertz is sample rate in 4000 Hz to 15000 Hz range
and (sn) causes nibbles to be swapped before playing. Maximum file
size is determined by the free amount of TPA. You should be able
to play files up to 46K in most cases.
ZBRAW SAVATAGE.RAW 8000
Plays SAVATAGE.RAW at 8000 Hz.
Some four bit sound files have their nibbles swapped. This causes
distortion if played in the standard format Z Blaster Kit uses.
The standard format is storing two samples per nibble starting with
the high nibble. To play a file with the first nibble in the low
position:
ZBRAW BIX.RAW 7000 SN
Swaps nibbles and plays BIX.RAW at 7000 Hz.
ZBRAW 1:B:TEST.RAW 15000 SN
Swaps nibbles and plays B1:TEST.RAW at 15000 Hz.
Z BLASTER CONVERT
ZBCNV.COM enables you to convert a uncompressed eight bit sound
file (.SND, etc) to a four bit (.RAW, etc) file. To convert a file
use:
ZBCNV {U:D:filespec} {U:D:filespec}
(U:D:) is any valid CP/M user and drive and (filespec) is any valid
CP/M file name. The first name is the eight bit file and the
second is the four bit file. While ZBCNV will convert any size
file remember that you can only play about a 46K four bit file.
This limits the eight bit file to about 92K.
ZBRAW SAVATAGE.SND SAVATAGE.RAW
Converts SAVATAGE.SND into SAVATAGE.RAW with standard nibble
ordering. This allows you to play with ZBRAW SAVATAGE.RAW 8000
after conversion.
HINTS AND TIPS
If the file sounds distorted during play back and you are not sure
of the nibble ordering use SN option of ZBRAW. If that does not
help or sounds worse then the file is of poor quality. There are
a lot of poor quality sound files created with "home made"
digitizers.
You can run ZBCNV under the MYZ80 Z80 emulator for MS DOS. I'm
running MYZ80 under Windows 3.1 which allows me to convert sound
files much faster. I use 22DISK to export the sound files to a
Epson QX-10 format disk which the 1571 can read in CP/M mode.
If you have a PC with a 8 bit sound card the use that as your sound
file source. I'm using a Sound Blaster Pro stereo card to capture
my sounds. There are many PD sound file conversion utilities that
strip the header information and give you a uncompressed eight bit
image. I use a utility to convert .VOC files to .SND format.
You can get help from ZBRAW and ZBCNV by running them without any
parameters.
