DigiUbik (c) 1991 GHungerford
DigiUbik is a digital sound file editing tool. Digitized
sound samples may be merged, appended, packed or played.
Loading Buffers:
To load a buffer, click on the number of the buffer you want to load.
If the buffer is already loaded, you'll be given a choice of clearing
it out and continuing or of cancelling the request.
If you continue (or the buffer wasn't loaded), you will be shown a
file selector box. Select the file you want or cancel the request.
If you cancel the request, the buffer will remain empty. If you get
an 'Insufficient Ram' message or a file won't load, try clearing out
any loaded buffers this way to gain space.
If the file has the extension '.PAK', then it is assumed to be a packed
file and will be loaded accordingly. Packing is a way of storing digi-
tal sound files in one half the space.
Frequency:
Click directly on the Frequency to change it.
0 = 5 Khz
1 = 7.5 Khz
2 = 10 Khz
3 = 15 Khz
4 = 20 Khz
5 = 31 Khz
6 = 40 Khz (requires cartridge sound output)
7 = 50 Khz ( ditto )
UpDownButton:
(The arrow in the box to the right of the Target Buffer display.)
Clicking on this button will toggle the arrow up and down.
Initially the arrow is pointing up, indicating that the numbered
buttons (like the Frequency button above) will increase when
clicked on. Likewise, if the UpDownButton is set to a down arrow,
the numbers will decrease when clicked on.
Target Buffer:
The 'current' buffer to be played, saved or packed - the destination
buffer of merged and appended buffers. You will be notified if you
are about to overwrite a currently loaded buffer. Click directly on
the Target Buffer number to change it.
Sources:
The source buffers that are to be merged or appended. Both source
buffers may be the same (for appending a buffer to itself).
Merge Percent:
These two percentages relate to the source buffers. A 50/50 setting
will merge the two sources equally. If the volume of one source
is too low or one source needs to be emphasized, increase the Merge
Percent for that source buffer.
Play:
If the current Target Buffer is loaded then that buffer will be played.
Append:
Joins the current source buffers and places the result in the current
Target Buffer.
Pack:
Packs the current Target Buffer to a disk file. The sound quality
is lessened, but the file size is one half of the original. Packed
files MUST have the '.PAK' extension to load back properly. Packing
is accomplished by trashing the lower nybble of each byte in the
sample.
Save:
Saves the current Target Buffer to disk.
Merge:
Mixes the sounds from the source buffers and places the result
in the current Target Buffer.
NOTES:
Since sound files are just a bunch of bytes, this program
can also be used to quickly append ANY kind of file to ANY
kind of file.
Packing ONLY makes sense for sound files and will trash any
other type of data.
Although only proper sound data files normally make sense,
any file may be listened to. Usually this equates to a lot
of noise, but some programs (games) have sounds hidden in them...
