Off the top of my head, something could be put together with a shell
script using the jack_connect program. If you are OK with a single
purpose script that runs and connects two specific known programs,
this will be easy, making it work with arbitrary programs provided as
arguments is better done with something like lash, or patch-bay
persistence.

On that note, is there a JACK command-line utility that is as easy to

That would be cool, if a, b, and c were JACK-enabled applications:
$ jack-pipe a : b : c
So much faster than opening up qjackctl and making connections
manually. Okay, clearly this doesn't handle multichannel very well
however.

Hi all,
I am using mplayer, sox and tee to capture streaming internet radio
and send it both to an audio recognition program and to a file
(recording).
This is how I do it:
mplayer -playlist {url} -nocache -af volnorm -msglevel all=1 -nolirc
-vc dummy -vo null -ao pcm:file={$fifo1} &
sox -S {$fifo1} -c 1 -r 8000 -t wav - resample | tee {$recording} |
tee {$fifo2} & ......
$fifo1 and $fifo2 are named pipes, $fifo2 is processed by an audio
recognition program. The idea is that the audio is converted to low
quality wav (8000Hz mono) after which it is fed to the program and
simultaneously recorded.
Not that I want to suggest anything to massively off-topic, but I hope
you realize that this is a perfect example of the kind of scenario
that JACK was designed to handle.
