Thank you for this nice solution Erich, and thank you Eric for your
comments on ulimit.
I managed to get things to work this way. Nevertheless Eric, if you have
a moment to peek into the code and see why sox is keeping files open, it
would be fantastic and could prevent similar questions coming up again.
In order to provide sox with the information necessary to write its
output file from raw data, I query the input file for its properties
using soxi or sox --i .I discovered that sox --i -e yields
Signed Integer PCM
while the -e flag for setting the encoding expects a different
wording (from manpage):
signed-integer
I wonder if the encoding reported by soxi should be made identical to
the one required by sox in order to ease setting it in scripts?
Thank you both again,
best, Peter
