Intuitively this is an impossible problem - if the material being
recorded changes character significantly (say becomes silence) then
some sort of estimate of VBR recording time will not be able to work.
You could probably bound the problem and give a worst case recording
time, or use the compression on the current recording and extrapolate
this to the remaining disk to estimate a likely recording time.
I'd display the worst case recording time myself and live with it
being overly pessimistic.

Hi,
I need this to calculate/estimate remaining recording time based on
available temp drive space.
I was just wondering if anyone has a good forecasting algorithm for
estimating the size of a compressed audio file.
The uncompressed PCM is trivial, as should the CBR case be. The
problem is mainly for VBR type files.
Any pointers and help will be greatly appreciated!
Thanks in advance,
