[LAU] automated recording / processing / encoding to mp3

[Brian Dunn]

LAUsers:

I am trying to set up a box in a sound booth to take in a mono analog  
speech signal off of a board and then eventually output a id3 tagged  
mp3.

* easy to for myself and the other (non linux user) sound team members.
* be capable of capturing for <= 2 hours.
* simple id3 tagging (allow user to set the speaker and the title )
* apply compressor, remove DC offset, and normalize.
* encode as mp3 with reasonable quality for a voice recording (any  
suggestions here?)

My first thought for capturing the signal was Ardour (of course), but  
now I'm thinking that may be overkill.  It may be best to have the  
whole thing be basically a script. to that end,
* a good command line DAW?
* minimum hardware for the computer / sound card?
* anyone built a similar automated chain?
* any other suggestions?

thanks.
