hrtfer on 3.4 Mac 881

Subjecthrtfer on 3.4 Mac 881
Hello Csounders,

I have found that there are clicks in the output of the hrtfer.
Has anyone else had this problem and if so how to fix it ?

Below is the instrument I used (it's basicly the same as the
example given in the manual except I used a line instead
of a linseg).  Audio is fed in via a global audio variable, ga1.
I thought it may ha ve something to do with the amount of
change in the kaz and kel variable but the clicks appeared
even when smaller ranges where given, just not as many.

instr 3 ;head thing
kaz                      line p4,p3,p5
kel                      line p6,p3,p7
aleft,aright    hrtfer ga1, kaz, kel, "HRTFcompact"
aleftscale      = aleft * 200
arightscale     = aright * 200

outs aleftscale, arightscale
ga1=0
endin

Anyone ?

I'm on a PowerComputing PowerTower 180e, MacOs 7.5.5.

I worked with snap1, but had to do the following to make the crash
happen.
Please bear with me, especially if I do some irregular things.

1> The orc/sco setup I was using was meant for long (2-3 min) stereo
files,
so I had to modify snap1.aiff. Of course, this might invalidate using
snap1.aiff
in the first place. I open the mono snap1 in SoundEdit 16 2.0.4,
copy/paste the 
mono channel into a new track to create "stereo". Then copy/paste both
channels
9 times to create a 10 sec file.

2> From Csound use sndinfo to check the length of the file (10.00)
seconds.

3> Double check that 10 is the p3 value for the inst call in the sco.

4> Generate using the sco and orc attached at end.

OR

4> Use a simple "soundin" to read the 10 sec file.

Now, the big sco/orc below is probably more dense than it needs to be,
and you'll
probably find that I'm doing something inefficiently or wrong. But this
used to work
flawlessly in 0.2.0.

My 0.3.1 workaround is to make the inst call less than the len of the
source
sound file by about 4 secs, even when all I'm doing is using a simple
"soundin"
construction instead of the longer inst below.

I hate to think that the crash is related to the timout construction I'm
using
(I've gleaned the construction I use from what's out there and basic
trial and
error) since it seems more than a coincidence that I'm trying to cut off
the instr
so that the end of the file isn't reached within the last timout loop.

When the Mac crashes, it usually freezes totally, requiring
 to wake it up. The 10sec temp file is not
visible,
but my available free space is reduced as if it were. Running Norton
Utilities 
tells me that I have a b-tree error, etc.

Ironically, I upgraded to Norton Utilities 3.5 this weekend, and the new
CrashGuard utility stepped in during the crash to tell me that perf
had hit a PowerPC Exception - Unmapped memeory exception. And from there
on 
it was three bus errors followed by a miscellaneous harware exception.
Not too
useful I suppose since there's no stack trace. When I've run this with
MacsBug,
the crash bypasses the debugger too.

I hope that this helps, let me know what more I can do.

Peter,

I experienced the same problem in the PC version.  Somebody said it is due
to the interpolation.  The hrtf used here is a compact data set.  It
probably does not include enough points for a good interpolation.

If you set to a fixed point, you probably will not hear the clicks.

regard,

Augie

but what tricks are involved in getting a full-duplex, rt
signal-processor--is there a short piece of example-code anywhere? For
example, when I run csound as follows,

csound -i devaudio -o devaudio soundin.orc soundin.sco
 
I get: error while reading DSP device for audio

And when I run it without the '-o audio', data in the dispfft window is
clearly dependent upon the amplitude of the source, but is shaped
improperly, like a bowl with peaks at the extreme left and right.

Here's my main instrument, which should at least illustrate my
intentions (not much of an fx box yet):
intr 1
        ainput in
        ar=ainput
        ag=ar
        dispfft ainput, .05, 1024
outs    ar, ag
        endin

If it matters, I have a redhat linux box with a gus pnp & the ultrasound
project drivers.

I know that this is a bit off topic, but I thought that some of the 
people using CSound might be interested in this project (feel free to 
suggest more appriate places to post things such as this). 

---

illegal art is a new label dedicated to releasing music that is made 
up entirely from pre-existing music.  Our first project is called 
"decontructing beck" and will consist of music made exclusively from samples 
off of Beck's releases (whether this is done out of respect or disdain for 
the MTV icon remains to be seen). 

We initially invited a few people to contribute to this compilation 
and have thus far received some interesting submissions.  We are now 
sending out a general invitation to all artists who work with sample-based 
music to contribute to this project.  We anticipate finishing the project 
towards the end of this summer and would encourage anyone interested in 
being involved to contact us at the address below so that we can further 
discuss the details of the release (deadlines for submissions, etc.).  

Also since this release will only be available for a short time period 
(for various reasons) we have a mailing list for those interested in 
obtaining the release as soon as it is available.  If you would like to be 
added to our e-mailing list please send the message "subscribe to 
mailing list" to the e-mail address below.  

Feel free to pass this invitation along to anyone else who you think 
might be interested in it.  Thanks!

Hmmm...  I always use "-odac" for real-time audio output in Linux.  The
-odevaudio has never worked correctly for me.

I remember that devaudio would work but it was very noisy...

I don't recall, but was the gus pnp truly full duplex?  I ended up
buying
the Audiotrix Pro from Mediatrix just for that reason.  My digital audio 
software for Win95 suggested that I buy either the Card-D, Audiotrix
Pro,
or the Turtle Beach Multisound in order to get full duplex.  After I
found
Linux drivers for the Audiotrix board (using OSS from 4front tech), the
decision 
was easy..

I'd be curious to find out where all this goes..  This could lead to
some
powerful csound capabilities!

I have fixed (I hope) the '+' in p2 bug and the AIFF header reading bug
in perf and put a fix up on the Mills ftp site in:

pub/ccm/csound.ppc/perf032_fix.sea.hqx.

I will put this in the release package ASAP, meanwhile those of you that
have 0.3.1b0 should get this perf if you use the '+' score feature or
AIFF files for input.

Thanks for the bug reports.

Peter,

I experienced the same problem in the PC version.  Somebody said it is due
to the interpolation.  The hrtf used here is a compact data set.  It
probably does not include enough points for a good interpolation.

If you set to a fixed point, you probably will not hear the clicks.

regard,

Augie
