I used audacity to record a webcast radio program which
lasted about 1.5 hours, maybe less.
It took up more than 2.4GB (decimal) of disk space!!
Obviously, .au format is not the ideal format for
cases where "hi fidelity" is not a concern.
Is there a way to get audacity to use an mp3 library
to compress the audio on the fly so as not to chew
up so much disk space?
