HOW-TO grab streaming audio data, write it to a file and listen to it at the same time

12 Feb

shell-fm, tee and vlc are just good enough:

man shell-fm-config:

extern = command
On some platforms, Shell.FM is still unable to play streams properly. This option enables you to use Shell.FM for stream control, but use another player for the playback. The stream will
be written to STDIN of the external player.

OK then, let’s edit our .shell-fm/shell-fm.rc:

extern = tee | vlc -

in order to tell it to send its mp3 output tee which takes the data, writes it to the file and passes a copy of the data to the STDIN which is then grabbed by vlc and played through (to stop the system I prefer to stop vlc first and then shell-fm):

$ shell-fm lastfm://artist/Brad+Mehldau/similarartists

Thanks to Jonas Kramer for the wonderful shell-fm utility (and thanks to vlc and tee programmers). Thanks to Brad Mehldau for the nice jazz as usual.

PS: Don’t forget to check Emacs mode for shell-fm.
