| Excuse me, please, for off topic question.
I never worked with Mac (though I'd like to) but now
it's necessary for me to understand format of Sound designer's
files deeply. First, I'll be happy to see any comments about it.
And second (very important), can anybody explain what is
the thing called 'fork' (data fork, resource fork). Or where can I
find explanation (easy enough for "PC-thinking")?
Thanks.

Yes
I think you must use the 68k version. The non FPU are for PPC. (the
fpu thing is the processor's architecture, so having or not depends on
the processors. THe 603,604, etc... don't have Fpu, because it's built
in the processor, so u must not use FPU version, it might crash or
extremely slow down things, depending on the application. the quadras
have 68040 processors so i think u should use the 68k version. THe 881,
well i frankly don't know about. I have a PPC and use the excelent
3.56PPC version.
Cheers.

well, I think you should hear this from a long time Mac user.... from the
days of the Mac Plus......
there 2 versions of the 68040 used in the Macintosh. The 68040 and the
68LC040. The LC version has a disabled/broken fpu which means it doesnt
work. The one you use will depend on the type of 68k Mac you have... You
have a Quadra 900 or 950 then you have an 68040 with the 68881 fpu (math
co-processor/floating point unit). the non-fpu will run on your machine
but it will run slower than the version with the fpu. Csound is fpu
intensive. So, get the fpu version if you have a Quadra 800, 900, 950 and
some 650 machines.... the Mac IIci (68030)also has an fpu. Note that you
can add an fpu to most old Macs (LC, LCII, LCIII, color classic, SE, si,
etc.....)
you could run the non-fpu 68k version on a PPC, but why would you run any
version of the 68k binary on an PPC?
On PPC under 68k emulation the fpu version will not even run unless you
have an fpu emulator installed.... note that the UMAX clones shipped with
the PowerFPU emulation extension so you could run the fpu version on these
PPCs.... but again why? it would be slow as hell....

Hi all,
DirectCsound update 3.02 available.
This version has only a tiny modification in the secondary buffer
initialization, because some guys of this list adviced me to be unable
to initalize secondary buffers (and consequently to use all 3d audio
opcodes).
Please test this version and tell me if the problem is still present,
because, on my machine, previous version was running OK on my machine
too, so I'm preceeding as a blind.

The data fork is the standard file, as on pc/unix etc.
The resource fork is a separate file (ie it is not hidden before
or after the data fork), which usually contains highly structured data.
Resources are convenient for programmers, since the special system
resource file operations do most work maintaining the file layout etc,
and you can access the parts using identifiers or names.
Also they may be replaced as needed without necessarily disrupting
the rest of the program.
The following may not reflect the "actual" structure on a Mac
hard disk, but if you copy Mac files to a PC diskette, you'll
get up to three components:
(1) The data fork is the standard file - a wav or aiff file
or any other portable file does not have any resource fork.
(2) In every Mac directory there is a subdirectory called
"Resource.frk". This may (or may not) contain files with the
same names as the data fork, plus any mac files which only
have resources and no data. That's the home of the resource forks.
(3) In every directory there is a special file called "Finder.dat".
This has all display information used by the MacOS Finder application:
Position of icons for files the directory etc, and more importantly
the long file names. Mac names for PC files will be chopped to the
DOS-type 8.3 format. If you open Finder.dat in a text editor you'll
see the DOS file name followed by the Mac name (there should be
some app that can do the renaming for us, but I haven't looked hard).
All components are handled transparently by Finder, so the user
often need not bother about the distinction - move or rename one,
and the other follows etc.
This is perhaps not exactly how it really looks on a Mac hard disk,
but it helped me a little understanding how the magic is done.
I suppose it shouldn't be regarded as much more strange than
other file systems' way of hiding the actual layout of data blocks
on the hard drive...
Cheers,

Hi Sergey. I'm just a (very green) beginner at programming the Mac, though
I've had one for several years. This is an excerpt from the Building and
Managing Programs in MPW [Macintosh Programming Workshop] manual (free
download from Apple Developers web site, it is in pdf format so if you want
to look at it, you should be able to do so from an IBM provided you have
Adobe Acrobat's reader, also a free download from Adobe's web site)
C H A P T E R 1
Building Macintosh Programs
1-4 What Is a Macintosh Program?
What Is a Macintosh Program? 1
A Macintosh program consists of code (CPU instructions) and data. The code
and data can be stored in either the data fork or the resource fork of a
program
file (or possibly both).
The location of the program's executable code depends upon the type of
program and the runtime architecture used. Programs built for the PowerPC
runtime store all their code in the data fork. Classic 68K runtime programs
store their code in the resource fork as code resources: for example, 'CODE',
'DRVR', or 'INIT' resources. CFM-68K runtime programs are a hybrid, and,
depending on the type of program, may store their code in either the data fork
or the resource fork.
Data used by the program, as opposed to data on which the program operates,
is stored in noncode resources: for example, 'WDEF', 'SIZE', 'DITL', or 'DLOG'
resources. You use the resource compiler Rez or a resource editor to create
noncode resources. Chapter 6, "Creating Noncode Resources and Manipulating
Resources," describes how to write and build noncode resources.
Note
The term code resource denotes any resource (which is
found in the resource fork of a file) that contains
executable code. A 'CODE' resource, however, refers
specifically to a resource of type 'CODE'.

Subject: Pink noise generation update

Hi All,
My page concerning the DSP generation of pink noise (1/f noise)
http://www.firstpr.com.au/dsp/pink-noise/
has been updated to include:
1 - Paul Kellet's "instrumentation grade" pinking filter for white
noise, which produces pink noise +/- 0.05dB above 9.2Hz
(44100Hz sampling rate).
2 - His simpler "economy" grade pinking filter which is accurate
to +/-0.5dB.
3 - Allan Herrimen's graphical analyis of the responsed of these two
and of Robert Bristow-Johnson's three pole and three zero filter.
4 - Allan's refinement to his analysis of the Voss-McCartney
algorithm of adding multiple white noise sources at lower and
lower octaves.
The contributors to this project are on the Music DSP mailing list,
details of which are at my page.
- Robin
