Bearing in mind that everything in linux is a file it should,
in theory,be relatively easy to divert say part of a radio
broadcast into sound file; But how does one go about it -
any ideas anyone ?

Well if your talking about saving audio to a file there are many ways to do that. You can use the command arecord to save audio from your microphone directly , or you can use streamripper to save shoutcasts streams. Have a look at this blog post on how to do more audio recording. http://jordilin.wordpress.com/2006/0...-command-line/

Also don't forget about audacity its a really good audio recorder / editor. Keep this in mind as well that saving the audio to a file it will be in RAW format and will not be compressed so if your wanting to encode it to say like an MP3 you will need to install lame, which is an MP3 encoder.
