Documentation for DigiEdit Version 1.00
By Edmund E. Aycock (c)1987
Well I finally got around to finishing Version 1.00 of
my digitized sound file player/editor. This version has a
few major improvements since the last that I will explain
below but before I start let me say that DigiEdit is best
used with a full blown sound editor like DigiSound from
Alpha or STReplay from MichTron. DigiEdit's most powerful
feature is it's ability to "Convert" sounds from one format
to the other and back again (i.e. STReplay->DigiSound or
DigiSound->STReplay). I have even used it to convert some
Macintosh SoundCap, SoundWave, and System "snd" resources
from my Magic Sac (Thank you Dave, you are a Minor God) to
Pure Data which can be loaded into DigiSound, played and
they sound GREAT! I believe it can be used to even convert
Amiga sound files but since I wouldn't be caught dead with
an Amiga I couldn't say for sure. On to the good stuff.
There are four files included in the DigiEdit Archive,
what they are follows:
DIGIEDIT.PRG The DigiEdit GEM Application.
DIGIEDIT.RSC The DigiEdit MonoChrome Resource.
DIGIEDIX.RSC The DigiEdit Medium Color Resource.
DIGISND.RSC The DigiEdit Startup Sound Resource.
(A slightly modified Lt. Yar)
Be sure that the correct resource for your type of monitor
is included on the disk that you run DigiEdit from. You don't
have to have the "DIGISND.RSC" file on the disk if you really
don't want to but I like a little greeting! You can take any
standard DigiSound "Saved" file and rename it to "DIGISND.RSC"
and DigiEdit will load it and play it on startup.
When you launch (launch? Mac leftover!) the application
you will see a 100% GEM program as I feel they all should be
written! All menu functions are available from the keyboard
using the OPTION key and one letter. I make full use of a
GEM "Side-Menu" and ALL ICONS are functional! The application
is pretty straight forward except for the conversion process.
To convert files: Load a sound file. The program will
ask you if you want to load a Standard DigiSound file or a
Pure Data file. Realize a Pure Data file can be ANY TYPE of
data, not just sound! Pure Data is what you use to load
STReplay files(SPL or SND). After loading you will be told
that the file will be saved in Pure Data format. This means
that you won't be able to listen to it unless you convert
it, then use DigiSound or STReplay to "Stretch" or "Squeeze"
it. This must be done due to slight differences in the two
digitizer programs. To convert STReplay to DigiSound: Load
the STReplay file as Pure Data, Convert it, Save it, then use
DigiSound to make it sound correct(Stretch or Squeeze). If
you don't have DigiSound you will only be able to listen to
it with DigiEdit, however even thought you can adjust the
Sampling Rate it may still sound a little slow or fast. To
convert DigiSound to STReplay: Load the DigiSound file as
Pure Data, convert it, Save it, then use STReplay to make it
sound correct. To change the sampling rate of a DigiSound
file load the file as "Digi", select the "Rate" Icon, set
your new choice, then save it. The DigiSound file will be
saved with the new sampling rate as part of the file and
is playable with any of my DigiSound sound players(i.e.
PLAYDIGI.PRG, STARTSND.PRG). The best way to learn it is to
use it! Don't be afraid to goof around! I love messing
around with sounds. Special thanks to Tim Purves for the
help and Digital Research for GEM, they're the Greatest!
So Long And Thanks For All The Fish,

P.S. I can't seem to get it to crash, but if you do please
let me know about it! -Thanks-
