scipy - Calculate energy to reverberation ratio in python -


hi new signal processing , trying out research paper. here formula need with

std[ f1,f2][h( f )] = e[ f1,f2][h2( f )^2]- 􀀀e^2[ f1,f2][h( f )]

where h( f ) denotes fourier transform of rir , e[ f1,f2][] denotes taking empirical expectation on frequency band ranging f1 f2.

i have got fourier transform , hence magnitudes each frequency. dont how expected frequency on frequence band

here paper http://www.eecs.berkeley.edu/~jinming/papers/soundloc.pdf

in context "empirical expectation on frequency band" means average of argument frequencies f1 f2. frequencies defined boundaries of octaves or 1/3 octaves. take argument , calculate mean.
