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. (oh, and sorry if this mail gets sent to the list twice - i forgot to add the [pd] bit to the subject first time)
