Here's a repleat repeat of the READ.ME from NoiseTracker Vamps #2: Jukebox.
Could be a big project. Read carefully. (Some techie stuff on psychoacousitcs
too).

-----

Here's Dr. Tom's READ.ME file from NoiseTracker 1.0 Vamps
Jukebox Disk #2. Some psychoacoustics techie stuff, as well
as a   * ahem *   CALL FOR PROGRAMMERS. Read on. I'm posting
the disk on c.b.a2.

-----

For those of you using an Apple IIgs and the program
NOISETRACKER v 1.0, we have added a new feature peeked,
poked and called: VAMPS NOISETRACKER MODULES Magik Memory
Looper Automatic JukeBox.

This feature is a basic program that is named startup on
this disk.  It loads other specially designed files that are
required for use with the basic startup program, including
all  NOISETRACKER VAMPS music modules and then plays
NOISETRACKER VAMPS v1.0,  Music Module files, one after the
other.  The number of modules that can be loaded and played,
is limited only by the amount of RAM memory your IIgs has to
work with. This disk and the files/program are FREEWARE.
You can use any portion of this disk for any purpose you
wish.

To change the music modules that are loaded and played, you
can load and list the startup program, then change the
program REM line data information, at the end of the
program, containing the list of VAMPS NOISETRACKER music
modules, A thru F.   This disk requires at least 756K of RAM
to load and play the 6 songs on the disk.

*** -> WARNING <-***

This VAMPS DEMO DISK #2, was designed for use as a P8 (800K)
self-booting disk.  It is not compatable with GS/OS.  If you
attempt to launch this disk via any GS/OS system disk, it
will lock up.

I realized rather early in my VAMPS music work,  with
NoiseTracker v1.0, that some of the VAMPS music and wave
files were too large to be compatible with the animation
routine during the INTROMUSIC routine.   The larger, more
complex VAMPS MUSIC would sound like a warped CD, because
the INT & MEMORY MGR's, created a conflict.

I wanted to see a method devised that would allow me to save
my finished VAMPS music via NoiseTracker v1.0, as a module
file and retain the VAMPS encoding, that gave the
Psychoacoustic and 3-D (| Virtual Audio - Vortex |) 360
degree Global Stereo sound localization/spatial enhancement
binaural/transaural effects.  I also wanted to enhance the
sounds to near-coincident pairs, giving a good Blumlein
style imaging without excessive low frequency phase
differences.  The music on this disk also exhibits an
element of precedence effect and introduces a degree of
decorrelation between the channels which is good for the
subjective quantity of spaciousness.  A new enhancement has
also been added to simulate the illusion of near-perfect
pinna effects and sound shadowing effects, which are
responsible for accurate front-back and vertical perception.

(NOTES OF INTEREST)

Psychoacoustic research has determined that the localization
of sound is based upon four primary phenomena.  (1)
Interaural Time Difference or the differences in a sounds's
arrival time between the listeners ears,  (2) Interaural
Intensity Difference or the differences in a sound's volume
between the ears,  (3) Pinna Effects which result from phase
shifts and timbral changes caused by reflections in the
outer ear and (4) Shadowing of the head.  This phenomenon is
dependent upon where a sound emanates from around the
listener and its differing path lengths to the two ears via
the head and shoulders which results in perceived volume and
arrival time differences.  In addition, the listener's outer
ears and head will cause different reflections, refraction
and absorption effects to occur in relation to the sounds's
spectral content and angle of incidence.  I have attempted
to instill all of these effects in the music, presented on
this disk.

I wrote to the author of NoiseTracker, Olivier Goguel,
asking him if he knew of any way to design a VAMPS DEMO disk
that would allow me to retain the VAMPS encoding in
NoiseTracker Module files and play them all together, (one
after the other).  He was very helpful in assisting me with
these needs.  These new functions are on this VAMPS DEMO
DISK #2.

Now you have the VAMPS encoding retained in all the
NoiseTracker v1.0 music modules
and can now use VAMPS music modules in your own programs.
The VAMPS NOISETRACKER MODULE Magik Memory Looper Automatic
JukeBox, will do a  (Virtual) MEMORY LOAD and LOOPER of all
the music module files, playing them in full 360 degree
Global Stereo, with all of their VAMPS encoded effects, one
after the other.  If you get tired of listening to one, just
press any keyboard letter, the return key, spacebar, etc.
and the next music module will start playing.

I have 6 VAMPS (encoded) MUSIC MODULE files on this VAMPS
DEMO disk, set to load and play starting with the module
file named A, and progressing thru to F.  The music stops
after the ending of the last song and you can start up the
first song again after the last one ends, by pressing the
spacebar (twice).   If you press the spacebar only 1 time,
it will start the last song that was played again.  Pressing
the spacebar or any other key (3 times) will progress the
Jukebox to the second music mudule song, (B) etc. and so on.

I talked with Olivier Goguel at length last week and asked
him if he was going to do any update to NoiseTracker v1.0.
He told me he was not going to do any more updates.
I asked him if I could undertake the project to make updates
of NoiseTracker and he said  "YES", so (IF I CAN GET A
PROGRAMMING AND DEVELOPMENT TEAM TOGETHER), you can all look
forward to a new release of NoiseTracker GS v2.0, from me
sometime around Christmas of this year.  I plan to make some
extensive improvements and hope to redesign the program as a
GS/OS application program, which will be fully compatable
with the 6.0 system.   Some of the projected enhancements
will include the abilities to load and play music in the
following music file formats; synthLAB,  Music Studio and
Diversitune, plus several others, assuming that no conflicts
arise.   I'm also planning to develop an NDA to play all of
these formats as well as all of the current music file
formats that NoiseTracker v1.0 can load and play.

I would like to solicit help on this NoiseTracker update
project.  I'm not a programmer, just a sound engineer and I
need to get some good people together with me to help
develop an update for NoiseTracker.    Any programmers that
are real good in the language of C,and/or assembly, having a
good knowledge of the use of MERLIN 16 PLUS, please contact
me, if you would like to join the development team for this
project.  I need to get a team of programmers and developers
together, as soon as possible, to get the redesigned update
developed by Christmas, so I can give all the IIgs users a
real good Christmas present (FREEWARE) program, to dazzle
their ears with !   If anybody is interested in joining the
VAMPS/NOISETRACKER UPDATE team, please contact me at the
address or phone number noted below.

I've got around 40 more finished VAMPS music files and will
be releasing VAMPS DEMO DISKS every month, with new VAMPS
music.

This disk is: VAMPS DEMO # 2.  If you don't have the VAMPS
DEMO # 1 disk, you can download it from America-on-line, or
several other popular BBS's, around the country.  The VAMPS
DEMO DISK # 1 has a complete set of text files that give a
full review of what VAMPS are all about, and tells you what
the effects are, how they were developed and how you can use
them to create your own customized VAMPS music and
sound/samples.

The next VAMPS DEMO DISK (#3), which will be released in
late July or early August, will have an extensive and
comprehensive text file report on VAMPS 3-D MUSIC (Virtual
Audio Research Technology & Psychoacoustics).

Enjoy the MUSIC and let the MUSIC enjoy you !

I look forward to your reply and comments. I also welcome
any new music programs, music files or sound/sample files
you would like to submit for my review and/or use.
