I need to create a complex all-pole filter with the coefficients I got from an LPC signal analysis.
In Max, it doesn't seem possible to create this all-pole filter if the number of poles is greater than two.
I tested the filtergraph~ object which returns the suitable frequency response for an even number of poles (until 24).
But to implement it as an MSP filter, the only solution would consist in decomposing the all-pole coefficients into a set of bi-poles, i.e. a set of parallelized or cascaded biquad cells with 1. 0. 0. in the numerator.
Thank you in advance.
