Does anyone have an idea on computation algorithms for early/late ratios using
the waterfall spectra commonly avaible on portable analyzers?  I have done Leq
with such analyzers using simple BASIC code in the past...

I think that it is feasible to capture 20 to 100 spectra per second, and there
ought to be a compact summing rule-of thumb to get the needed ratios in a few 
seconds with captured data on-site...
