[PD] help with making a parametric EQ
from this site, in the section titled 'group delay' http://www.dspguru.com/info/terms/filtterm/index2.htm 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 EQ.
