BTW: the peak envelope part could be also implemented using fexpr~:

[fexpr~ max($x1[0], ($y[-1]*$f2)]

This has the advantage of not requiring a re-blocked subpatch with
blocksize=1. However, I wonder which is computationally less expensive.
Is there a rule of thumb whether [fexpr~] or [block~ 1] is faster?
