my solution might be more than you need, but I believe
that
sooperlooper has a command-line only mode now. it is a fantastic
looper.
Agreed -- but yes, I was looking for a lightweight alternative. I
found one, but it's ugly:
(while true; do flac -dc --force-raw-format --endian=little
--sign=signed loop.flac; done) | play -t raw -L -b 24 -r 48k -e s -
where play is from sox. Raw output concatenates nicely. One mistake in
the switches sends the speakers screaming, of course.
I'm not sure how to send raw samples to jack yet.
