'no complex interpretation'??? - I think anyone with knowledge of previous incidents would beg to differ!
I think what he is saying is unlike the FDR which charts and figures, this is just sound so you can hear it, as oppose ti interpret what those sounds may mean/reveal.
Regarding FDR and sensors depending where the explosion was and whether it or the end result in the rear severed the cabling there maybe some useful sensor info if they are lucky.
Basically they need duplicate cvr/fdr in the front or go to what what being propose during MH17 and have continuous data streaming of both, to an independent storage source which over writes BOTH at the same frequency as FDR (to avoid losing what may be useful cvr on long flights)
