vor pure voice it's enough to use bitrates lower that 32kbit/sec

I think Realaudio isn't that bad for this purpose (windows and linux encoder
exists).

for example the 16kbit codec uses 2kbytes/sec the 24kbit coded 3kbytes/sec

that means 1hour of realaudio at 24kbit = 3kbyte/sec*3600secs = 11MBytes

A 10GB disk can hold 1000 hours or speech , that is 500-1000 tapes.

John as you see compressed audio on disk isn't more expensive than tapes.

a 10GB disk costs almost nothing these days 
:-)

PS: IBM just rolling out 75GB (!) 3 1/2 inch SCSI disks , EIDE versions will
follow soon. (I think in the 50GB area but dirty cheap :-) )
