Subject: [CM] working with large data sets
Message-ID: <CAPYwR0_HRPR27W8pkx0jTHstvkDgrLixfn5AbT2O9dEAXxM5qA@mail.gmail.com>

Hello list,


I?m working with sonifying a large number of data points using grace. The
values are recorded as a .csv by another application, which I then open in
excel. From here, I have tried copying and pasting (paste special as
unformatted) into word (grace doesn't do anything when I try to replace ^M
or ^p) so I was using word for removing ^p and replacing with a space. I
realize grace might be working, but not be as obvious as word that it is
working on it.


Here are a couple specific problems:


1. formatting is a pain/fatal! both word and grace take minutes to paste
the data into a document, and word takes a few minutes just to search and
replace the ^p. I?ve tried to leave the data as is in the grace document
(if it works, it?s pretty enough for me), but I often get a crash just
trying to paste the data into a document in grace. Or a crash upon loading
the second 24000 point stream of data. (I'll need to load ten of these
24,000 streams) When I leave the document to do something else while it
churns, I get the spinning beach ball of doom when I return to
grace....aaaaand, as usual, just had grace crash again while typing this
while awaiting my paste.


When I try with raw (unformatted) data, I've had it crash as I load
(evaluate) the second 24,000 stream.


2. after I use Word to take out the ^p and replace with space, when I look
at the file with more in terminal, every number has a ^M (carriage return
in DOS/Windows-?!) in front of it and word won?t let me search and replace
the ^M. (^M is not a valid special character for the Find What box
according to MS word).


Here are my questions:


1. Is there a limit on the amount of data points you can load into memory,
or is it just the formatting characters gumming up the works?


2. And most important?can anyone outline a better way to work with big data
streams in grace?



Thanks for any help,

~L.

hi lynn the bridge from grace?s editor to s7 is intended as a code editor and simply isnt made for huge wads of data.  

I would use an external app like emacs to edit the data in a .scm file and then simply load that file i Grace (or more speciically, into s7, which grace uses.)   so the scheme file would look like
(define mydata ?(1 2 3
 ?.. 24,000
))

also with huge data its possible may run out of heap space. if thats the case and depending on what you are tring to do, you could switch to the CM2/CLM/Common Lisp. those packages work will and common lisp would probably handle the large data sets that you are using.

Not s7's heap -- it grows as needed.  You might run out
of RAM, but 24000 cells is just a megabyte worst case
and won't normally even trigger a GC.  If s7 by itself
dies, send me the data file.  (I routinely work with
millions of data points, so something else has to be
the culprit -- I edit 1GByte data files in emacs).

On editing out special chars, you can use s7 to do that,
control-p is 16, control-m 13 etc.  If possible, run
your test in a debugger (gdb in Linux/Mac) and send
me a stacktrace.

emacs for mac? I know Rick is/was a fan of Aquamacs.

I use emacsformacosx -- google "emacs for mac" and
I think you'll see it.  There are also comparisons
available online.  I used aquamacs originally, but
was not happy with it.  (I actually do all real
editing on linux, so my opinion is not worth a lot).

I was too excited to wait for advice, so I ended up googling just that,
Bil. emacsformacosx was the first hit and looked good enough to try.

I knew I had chosen wisely when I saw the emacs Psychotherapist in the Help
menu.

Hi,

I was trying to get back to looking at s7 as interpreter but I'm failing to compile for some reason.


I have s7.o, s7.h, and snd is working ok.  But I'm getting undefined ref errors trying to compile below and a little stumped what might be going wrong?  Seems like it's not finding something it needs.

    sc = s7_init();
    s7_load(sc, "/opt/snd-16/repl.scm");
    s7_eval_c_string(sc, "((*repl* 'run))");
    return(0);
}

Hi,

It seems like you compile s7 with "WITH_GMP" defined somehow.
Perhaps you have a mus-config.h file where WITH_GMP is defined?

I guess it compiles if you remove WITH_GMP from mus-config.h,
 or link in libgmp: -lgmp

As Kjetil points out, you must have configured Snd
with --with-gmp or somehow created mus-config.h
with WITH_GMP set to 1.  That file does not come with
s7 (on the theory that people will read the instructions).
If you want to use gmp, you'll need -lgmp -lmpfr -lmpc.
If not, just delete whatever is in mus-config.h and
recompile s7, or run configure again (for Snd) without
--with-gmp, make clean, make.

By the way, have you measured any difference in performance
for non-bignumbers when using WITH_GMP?

The gmp version is always slower, sometimes a lot slower
(more than a factor of 10).  I was using gmp/mpfr for
some (for lack of a less pompous word) research and
didn't care about the speed.  In numerical contexts,
the multiprecision library calls completely dominate
(99% of the compute time), so I didn't try to optimize
the other 1%.  I plead lack of time and energy!
I've reached that point in life that if I try to
work harder, I instantly fall asleep.

Hi,

snd configure...

./configure  --with-s7 --with-gsl --with-motif --with-gl --with-gmp --with-alsa CFLAGS=HAVE_COMPLEX_NUMBERS CFLAGS=HAVE_COMPLEX_TRIG CFLAGS="-I/usr/include/linux/param.h"


Oops, I guess I did compile with gimp.  I'm not sure why I did that.  Must have been something I was trying to see perhaps related to gl.  Thanks so much for pointing out that problem.


re: all my compile times are usually over a minute, but I've been using lots of lets set!, and patterns, so I figured that was it.  I'll recompile snd without gimp and see how that goes.


Regards,

Jim

Subject: [CM] tank reverb
Message-ID: <87bmz9mohm.fsf@bek.no>

Hi all.

Tom Erbe visited us here in Oslo a week ago, and talked about
"Erbe-Verb" and other recent work he's done on reverbs.  In his great
presentation he mentioned a paper by Jon Dattorro: "Effect Design #1"
describing a 'tank-style' plate-reverb amongst other things.  I beleive
it was reverse-engineered from one of the early Lexicon digital reverbs?

I hadn't noticed the paper before, despite everybody else in the room
seeming to be familiar with it.  Anyway, it sparked me into setting up
something similar in CLM/SND (attached).

Albeit somewhat slow, it sounds quite good with many different types of
input.  The 'tank' is unity gain, so setting decay=1 creates a nice
'freeze' effect.  See some suggested settings at the example calls at
the bottom of the file.

Note: there are 2 minor differences in the tap-section from those in
Dattorro's paper.  I'll perhaps fix these later, if noone gets there
before me.

Currently only stereo.  Should be easy to extend (to e.g. quad or FOA)
by setting up further sets of taps from the same tank.  I'll perhaps do
more tests with this when i get time.

Have fun.

Subject: [CM] clm delay offset for tap?
Message-ID: <87y42cicig.fsf@bek.no>

Hi Bill, others.

I'm confused about (positive) offset argument to tap.

Negative offsets yields perhaps expected results, but positive offsets
starts pulling values from what seems an odd offset into the line.

(set! (*s7* 'print-length) 20)

(define d1 (make-delay 10))

(do ((i 0 (+ 1 i)))
    ((= i 10))
  (delay d1 i))

(mus-data d1)
=> (float-vector 0.0 1.0 2.0 3.0 4.0 5.0 6.0 7.0 8.0 9.0)

(tap d1)
=> 0.0
(tap d1 1)
=> 5.0
(tap d1 -1)
=> 1.0

(map (lambda (i) (tap d1 i)) '(0 1 2 3 4 5 6 7 8 9))
=> (0.0 5.0 4.0 3.0 2.0 1.0 0.0 9.0 8.0 7.0)

(map (lambda (i) (tap d1 i)) '(-0 -1 -2 -3 -4 -5 -6 -7 -8 -9))
=> (0.0 1.0 2.0 3.0 4.0 5.0 6.0 7.0 8.0 9.0)

Thanks for all help and guidance.

-anders

That's a bug with the modulus operator in c

(int)-1 % (unsigned int)10    => 5

(int)-1 % (int)10             => -1

That's very interesting -- I never noticed this!
Thanks very much for the bugfix -- I'll merge it into
my sources today -- then I need to look at all
the other % cases.

Yes, very good catch. Regarding unsigned integers, there have
been so many bugs caused by unsigned integers that I have
stopped using them completely in my software.
(The common bug is of course "(unsigned int)-1 < 0", and
variants of it, which is always false.)

I think Qt practices the same philosophy; no unsigned integers.
