#Noisevember! I revisited the Littlewood polynomial sound from day 2 of Noisevember. I thought to investigate a different sort of polynomial. Here, instead of polynomials with coefficients all ±1, the polynomials have coefficient ±1/(n+1) on the x^n term. As before, all roots of all such 15th degree polynomials are considered. (I really should create a gallery of these root plots so we can easily compare them.) Along the way, I realized I was making an error with the way I created "random" stereo that introduced a bunch of unneeded noise. So that's something! I'll have to go back and replace the Littlewood polynomial sound. soundcloud.com/matthew-m-conro…

Here's a plot of the roots (essentially the spectrogram of the sound).

A new track for #Noisevember. This one turned out really well, if I may say so. I used a piece of a field recording I did that includes a trombone and an escalator. This track is entirely in the spirit of tape music: though done digitally, it could, theoretically be done entirely with tape (with many, many, many splices). I hope you enjoy it!

Made using short piece of a short field recording of an elevator and a trombone in a parking garage.

Why recording audio when you could also print it? Here's one of my first test prints with tetra pak on the pasta press. Making myself familiar with the process in order to print some christmas cards later this year.
