Harrison/!FBackQTM/Docs/JingForm
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

Flashback jingle data format /decoded and decyphered by Phoenix/
----------------------------
This is the in-memory data format for Flashback's jingles, which are played
only occaisionally, in the background of the game. These are not stored as
files in the Flashback application, but can be found by memory-dumping the
application memory while Flashback is running.
There are 6 jingles used by the game, these are stored at the offsets:
&44, &F5, &170, &359, &4EE, &686
from &14B20, assuming the Flashback program is loaded at address &8000.
The format of jingle data at &14B20+<offset> is given below, be warned it is
the oddest music format I have ever seen...
Offset Meaning
------ ----------------------------------------------------------------------
+&0000 number of samples used by jingle
+&0001 speed of playback (&1 to &F)
+&0002 total number of events/lines in jingle
+&0003 sample blocks, 3 bytes per sample
+&00 sample number (0 if don't play this sample�)
+&01 logarithmic volume (0-127, 127 is max volume)
+&02 pitch correction value
to find the sample data, use:
block=&24A80+((sample numebr-1) * 16)
sample data offset from &24A80 = block!0 (8-bit linear signed data)
sample length, in bytes = block!4
�sample repeat offset = block!8
�sample repeat length = block!12
� sample number is only 0 for one sample, number 2, in jingle 1. This
causes a drum not to be played in this jingle. However it sounds
better if the drum IS played! So the QTM converter ignores this value
when 0 and adds the drum to the jingle which is probably what the
original version had.
� sample number 1 is the only repeating jingle sample. But it's repeat
offset and length are wrong, causing an anoying buzz in the sample.
The QTM converter corrects the repeat offset to 1830 and the length to
252, which gives a much clearer sound to the sample.
The repeating sample is also faded by 2 logarithmic volume settings
each time it repeats. This is odd, as the original version on the
Amiga could not possibly have faded logarithmically as the Amiga uses
linear volume handling only! The QTM converter changes this fade to
use a ProTracker linear fade effect instead which gives a similar
result, but is probably more correct.
+&0003+3*<number of samples>
events, 3 channels, with 2 bytes per channel = 6 bytes per event
format for each channel:
+&00 sample number byte
+&01 uncorrected note value
the note value has to be corrected for the sample, use:
note = (&C+<sample pitch correction>) AND &FF + <note> - 16
this corrected note value can be converted to a ProTracker note using
note 1 ="C-1", 2="C#1"... 35="A#3", 36="B-3". Some samples use note
correction values which after conversion give a note value below 1. To
ensure these samples play correctly on ProTracker players it is
necessary to make a second copy of the sample data, with each byte
doubled up - lowering the pitch by one octave, and use this doubled up
sample, with the low note value plus 12 to get the correct sound. The
reverse may be required for notes above 36.
if byte 1 of sample's data block = 0 (only on sample 2, jingle 1),
Flashback ignores the note, but the QTM converter won't because it
sounds better with it there!
