Polynomial paths

The polynomial path is slightly different than the other paths, in that it takes an argument, which is the degree of the polynomial to be generated. The degree can be in the range of 3 to 10 (poly(3) to poly(10)).

So you might use it like this:

20 40 poly(5) periods(7) range(50,10)
10000 -10000 poly(3) periods(4) range(30000,-30000)

Here's a datafile that uses polynomial paths, followed by a plot of the paths.

     output(sound.wav)    # name of the output soundfile
     duration(5)          # duration of the transformation
     initial(1)           # play the initial state for these many seconds
     final(1)             # play the final state for these many seconds

     10 20 poly(9)        # element 0: duration in samples
     -500 500 poly(10)    # amplitude

     40 80 poly(7)        # element 1: duration in samples
     10000 -10000 poly(8) # amplitude
    
     30 60 poly(5)        # element 2: duration in samples
     -10000 10000 poly(6) # amplitude
    
     20 40 poly(3)        # element 3: duration in samples
     1000 -1000 poly(4)   # amplitude
