UNIX pipe access protocol. Allow to read and write from UNIX pipes. The accepted syntax is: pipe:[<html><number></html> ] number is the number corresponding to the file descriptor of the pipe (e.g. 0 for stdin, 1 for stdout, 2 for stderr). If number is not specified, by default the stdout file descriptor will be used for writing, stdin for reading.
For example to read from stdin with avconv: cat test.wav | avconv -i pipe:0 # ...this is the same as... cat test.wav | avconv -i pipe:
For writing to stdout with avconv: avconv -i test.wav -f avi pipe:1 | cat > test.avi # ...this is the same as... avconv -i test.wav -f avi pipe: | cat > test.avi
Note that some formats (typically MOV), require the output protocol to be seekable, so they will fail with the pipe output protocol.

The PD patch : anarchasonification.pdFile:anarchasonification.pd and to check the audio device :
puredata -nogui -listdev audio input devices: 1. HDA Intel PCH (hardware) 2. HDA Intel PCH (plug-in) 3. Dummy (hardware) 4. Dummy (plug-in) audio output devices: 1. HDA Intel PCH (hardware) 2. HDA Intel PCH (plug-in) 3. Dummy (hardware) 4. Dummy (plug-in) API number 1
Not sure this step is necessary at the end …
To launch the patch :
puredata -nogui anarchasonification.pd
Labomedia's icecast server is configured in the patch for the moment … it should produce a devsonification.ogg on http://labomedia.org:8000

From Martin : As one of the (ir)responsible carvers (the other being Danja Vassiliev), the full command which danja used on the show was:
dd if=/dev/sdb | gst-launch-0.10 filesrc location=/dev/stdin ! queue ! tee name=v ! queue ! videoparse framerate=1 ! videoscale ! video/x-raw-yuv, width=40, height=30 ! videorate ! audioparse ! audiorate ! alsasink v. ! queue leaky=2 ! videoparse width=640 height=480 ! videoscale ! videorate ! xvimagesink sync=false
which also routes the HD data flow to the screen for unbroadcast visual feedback/fun!
Of course, as suggested a straight:
dd if=/dev/sdb of=/dev/dsp
would do the trcik albeit at a lower bitrate (and in both examples with /dev/sdb representing th USB-attached hard drive).
a test + jack
mplayer -demuxer rawaudio /dev/sdb -ao jack
might work (with more options to demuxer also).
Another option is:
cat /dev/sdb | ecasound -i stdin -o jack arecord arecord -D pulse
A test claude assuming jack is running at 48000 and want to resample from 8000
ecasound -f:s16_le,1,48000 -i:resample-hq,8000,sndfile,/usr/bin/mplayer,.raw -o:jack,system
is there something like a bridge, so i can route the audio signal to say supercollider 3 for further real time manipulations etc.anyone?
Marche !
