This sound was *supposed* to be the audio from a tweet, but it seems I uploaded the wrong file by mistake. This is actually some sound I generated a long time ago from some code rather longer than 140 characters.

It works (if I remember right) by having a feedback loop, and then a bunch of pitch trackers trying to track and eliminate any sustained tones that build up. I'm kind of glad I found it actually, because I've since managed to lose the code that generated it.

I would delete the erroneous upload, but a couple of people clicked "like" within half an hour of uploading it - if people like it then I'll happily leave it up for a bit :)  (though having said that, it has two likes but zero plays, so maybe those are just bots or something.)

Some random sound from my hard drive

Experimenting with iterated folding functions to generate deterministic chaotic sequences, synthesized with thru-zero frequency modulation in a Frap Tools Brenso complex oscillator. Studio live recording from 2022-06-17.

Butler - Night Machines

Revisiting some under-explored experiments in "self-directed" sonic systems from Design After Nature project in 2008.  An experiment in maximal minimal generative systems (most variety, from simplest system).

What if sound determined the conditions of it's unfolding? 

In this example a tap dripping controls its own playback.

Pseudocode: 

Play sample
Listen for onsets
If above threshold (probabilistically) 
- change direction and speed (as an inverse function of the frequency of strongest partial -- to create a simple homeostasis) 
- resynthesise N partials according to the original energy distribution at the point of onset detection.

This simple routine draws out and explores the latent rhythmic and spectral content of everyday sounds. Endlessly. 

Best listened late at night on headphones.

It has a of life of it's own that I find quite pleasing. But I have been living on my own for nearly 3 months now : )
