Faust Test Program for Generating Above Frequency-Response Examples

import("filter.lib"); % Faust v0.9.9.3 or later
N = 16;  % Allocated delay-line length
D = 5.4; % Requested delay
process  = impulse <: (
                       fdelay4(N, 1.5),
                       fdelay4(N, 1.6),
                       fdelay4(N, 1.7),
                       ...
                       fdelay4(N, 2.4),
                       fdelay4(N, 2.499),
                       fdelay4(N, 2.5));
// To see amplitude responses (for example):
// [in a shell]:
//   faust2octave tlagrange.dsp
// [at the Octave command prompt]:
//   plot(db(fft(faustout,1024)(1:512,:)));

// Alternate example for testing a range of orders
// process = 1-1' <: (fdelay1(N,D),
//                    fdelay2(N,D),
//                    fdelay3(N,D),
//                    fdelay4(N,D),
//                    fdelay5(N,D));
