[PD] max value of last n samples

[Dario Sanfilippo]

Hi, Roman. I guess that fexpr~ implies block 1 but probably a few other
things too: 256 instantiations of the feedback loop in my abstractions are
around 44% load whereas the same number of [fexpr~ max($x1[0],
$y[-1]*$x2[0])] are peaking at 95%.
