[PD] help with making a parametric EQ

from this site, in the section titled 'group delay'
i got an equation to calculate the 'group delay' of a linear FIR filter.
the equation is:
group delay = phase shift / -2pi
where phase shift is a value of radians / hz
can anyone please tell me how to calculate the phase shift with a basic FIR
filter in pd?
i'm hoping that if i can get that, then i can add/subtract the filtered
signal to a slightly delayed original signal to make a reasonable parametric
(oh, and sorry if this mail gets sent to the list twice - i forgot to add
the [pd] bit to the subject first time)
