#X text 439 12 framescore~ calculates a weighted similarity value for
two signal vectors. The value is weighted proportional to amplitude
\, so that comparisons made between higher value vectors have more
effect on the output than comparisons between low value vectors.;

#X text 437 80 Its use is in comparing alpha vectors from an rfft~
object where higher amplitude bins are weighted against low amplitude
bins. The maximum amplitude of the comparison vector on inlets 3+4
is used to scale the output value so that it always gives a score between
0 (no similarity) and 1 (identical alpha).;

#X text 438 158 Differences between the peak levels of the two vectors
may cause similarities in peak patterns to be missed. Since the cartesian-to-polar
conversion is done internally to the object \, <blocknorm~> may not
be used in the same way as it can with <framescore~> \, but since the
phase is not calculated as it is in <cartopol~> it is marginally less
CPU-intensive.;
