Hello,

I was reading this paper (http://www.kecl.ntt.co.jp/icl/signal/
nakatani/papers/icslp2002f0.pdf) and thought his Power spectra looks
ridiculously high.

using 10*log10(S) for the log power of spectrum S, S would need to be
about 10^9 to get that high dB range.

Or is there some standard that I'm unaware of?

In my matlab code, 10*log10(S./min(S)) gives a similar sized spectrum
as long as min(S) is not zero of course.


Any clarification would really be appreciated,

Adam
