in dB (with 1 normalized to 100 dB.) Output is bounded below by zero.

;
#X text 9 102 The analysis is "Hanning" (raised cosine) windowed.;
#X text 9 125 The optional creation arguments are the analysis window
size in samples \, and the period (the number of samples between analyses).
The latter should normally be a multiple of the DSP block size \, although
this isn't enforced.;
