(The "raw" format is also handled by libsndfile, but again, libsndfile is

Hey hey,
I tried to record over long periods of time (7-9 hours), using jack_rec,
which
apparently relies on libsndfile for writing
audiofiles. I started out
using
.wav, which broke off after 6:12:49 (2.1G). Next
time, I tried using the
file
extension .w64, which yielded the same result.
So, which format, or extension, would work for such periods of time?
Have you tried with jack_capture?
It uses libsndfile, too for codecs, but can dump raw samples to disk if
you tell
it to.
So, if libsndfile should be the limiting factor, try dumping the raw
frames and
later analyze those.
jack_capture -f raw -b FLOAT snoring.bin
Besides this option (and -f w64 and -f CAF which has been suggested),
jack_capture continue writing to new files in case you try to write more
data than
is supported, so you can even use the default wav format for large files.
