14th

(Loud noise with some high frequencies and no dynamic variation.)

Composed in mathr.co.uk/barry/v2/ , rendered in barry command line.

Reminds me of an electric train changing up gears when leaving a station.

Attached is just an excerpt of the start (first 2^23 samples), it continues indefinitely (technically, it will repeat after at most 2^64 samples, due to arbitrary computational limit).

Source code:

```
: wave { c t n -- o }
t t 1 n << 1 2 c * - - * n >> c 0 ~ * ^ * 1 n << 1 2 c * - + * n >> i8
;

: audio { c t -- o }
c t 19 wave
c t 18 wave
c t 17 wave
c t 16 wave
^ ^ ^
;

RUN audio
1 -> increment
0 -> time
```

(Last one I did was on the 3rd, not made enough time for noisevember this year...)

modulating PWM drone with echoed high pitched things and various fast kicks (with a bit of DC offset, sorry)

source code composed in mathr.co.uk/barry/v2/ , rendered to WAV using barry command line version.
