Warning. 4GB limit on wav file almost reached.
and the .wav file stops at 4GB.
So it does seem to be a problem with the 32-bit version of jack_capture.

I don't think so. Jeanette had the same problem

and I can't think of any reason why jack_capture should behave
differently when running on a 32 bit OS. It's far more likely to be
caused by the filesystem, or something else. I've cc-ed
Erik de Castro Lopo, the author of libsndfile. He probably
knows more about what could cause max file sizes of 2.1GB.
I didn't manage to get to the bottom of which piece of software
was causing the problem.
From the POV of libsndfile, it has had Large File
Support (which
makes file offsets 64 bit signed values) on 32 bit systems for over
a decade.
However, it is possible for other software using libsndfile incorrectly
(ie using a 32 bit integer to store file offsets) to cause this sort
of a problem, but then I would expect it to go wrong on 64 bit systems
because `int` is 32 bits there too. However on 32 bit Linux systems,
`long` whereas it us 64 bits on 64 bit Linux systems.

Hey hey,
after having tested with Ecasound and still gotten 2.1GB, I suspect the
package build of libsndfile for Arch and will write a mail to the Arch
mailinglist. Ecasound can write larger files, as tested with raw output. So
raw output is an alternative for the time being, but it would require
something like Ecasound to play it back, since only there a file format can be
specified.
Warmly yours and thanks for all the help,
Jeanette

Then you should take a look at the PKGBUILD. I already posted by my
previous mail.
Consider to read https://wiki.archlinux.org/index.php/Arch_Build_System
and just send such a request to arch general, if you already checked a
PKGBUILD yourself, but you still have questions.
If you found a culprit, then report the bug,
https://wiki.archlinux.org/index.php/Reporting_bug_guidelines and don't
send an email to the mailing list.

Ralf

The SoX program can of course convert nearly any format to nearly an other
format.
The -r option must be given to describe the sample rate of the raw file,
-e for signed, unsigned, float encoding format of samples, -b for size of
samples in number of bits, -c for number of channels in raw file. If no
changes are desired, just a header, then the last argument is the file
name with format extension.
I do not have a raw file to test this, but I think for a 48 k sample rate,
32 bit float as used by jack, 2 channel raw file the conversion would be:
sox -r 48k -e floating-point -b 32 -c 2 long_night.raw long_night.w64
Maybe ecasound does not use floating point, perhaps you configure 16 bit
output to save space. This should convert:
sox -r 48k -e signed-integer -b 16 -c 2 long_night.raw long_night.w64

Thanks for the commandline examples, if unused to SoX, it can take a
while to find the right options.

Since Kjetil guess seems to be plausible, I would try adding
"-D_FILE_OFFSET_BITS=64"
to the flags in makepkg.conf. I don't know, if it belongs there, but
since it doesn't take much time to test it, I wouldn't wait for a
reply, how to handle this and simply test it.

That may not help, because to get libsndfile to built on a 32 bit
system *without* large file support, I'm pretty sure they would have
had to patch the libsndfile sources.

Sorry Erik. I'd have reported this but I didn't think it was actually a bug
or issue with libsndfile at all.

I guess it doesn't happen that often that somebody needs audio
files > 2 GiB, let alone that the user at the same time needs to be on
32bit architecture, while e.g. Ubuntu flavours will drop 32bit support
soon.
