Digital Signal Processing agorithms required !!

  If anyone can supply the folowing information I would be 
'terminal'ly grateful.

  I need software to compress audio speech to a digital format at
a compression of around 4:1 - say 20 Kbits/second or better.

  Ideally I would like the algorithms necessary, but the code or the
software would serve the purpose. Public domain code would be 
preferable, to avoid licencing - but information on existing
commercial software would also be useful.

I'm acting as a middle man for someone else so apologies for any
potential vagueness. 

  Thanks in advance.

I don't usually think - therefore I'm not necessarily !
