Shorts #44: November 2024

This piece titled by Sonia Elks. Artistic feedback from Paula Gazzard.

There’s a principle in psychoacoustics called “stream segregation”. When you listen to somebody playing a lot of notes on the piano, but there’s a clear melody, this is because your brain groups some of the notes together. It “segregates” “streams” of notes by pitch. However, there are only so many streams you can recognise at a time. If you have more than that, the phenomenon is called “wall of noise.” In that case, your brain doesn’t know where the melody is. A constantly changing texture has some voices seem to come to the front and then retreat. No two people hear a wall of noise in the same way.

This piece has 47 different voices of sinusoidal grains. Each voice varies it’s pitch and panning position very slightly with every note. Each note is extremely short, although they do gradually double in average duration and then return to their original lengths. The longer pitches become “glissons”, which is a short sine wave that moves from one pitch to another instead of staying steady. The very end overlaps the 47 granular voices with 47 glissandos.

Shorts: #29 Raining Up

[play] Shorts: #29 Raining Up (2009)

Commissioned and titled by Autumn Looijen

This piece was created using a MOTM Synthesizer and mixed in Ardour. There were several false starts. I had been doing field recordings of storms and for a while, every artificial sound I made seemed to also sound like weather. The title Autumn chose seems to indicate that I didn’t quite get away from weather-related sounds.

I have started accepting commissions of one minute pieces again, and I’ve dropped the price since the last round. If you’d like to commission me, check out my online shop thing. Order now to beat the holiday rush!

Joystick Intermezzo

[play]Joystick Intermezzo (2008)

All of my SuperCollider pieces require several silent seconds to clear existing memory, pre-compute data and load joystick drivers. I find it helpful in many circumstances to play short tape pieces as intermezzos while other, longer pieces, get ready to play. This particular one is designed to be used between pieces involving an old fashioned, large joystick. I timed how long it takes to load pieces that involve that joystick and it tends to be around 40 seconds, so this intermezzo is 45 seconds long.

The musical sounds are generated in SuperCollider, using pulse width modulation, constrained to 8 bit resolution, to give it a retro videogame sound. The game sound FX are from Wolfenstein 3d, the first first person shooter, in front of which I wasted many many hours of my youth. Thanks to Eric Bumstead who actually had a copy of it!

Phreaking

[play]Phreaking (2008)

I wrote this piece for BrumCon 07. The con was sponsored by our local 2600 group, so I decided to use telephone in-line signaling codes as source materials. I spent a lot of time readin up on phone phreaking, which was just so completely cool. I never did it as a kid because the threats my dad made against me were so dire. But man, it was awesome!

The piece, though, is slightly silly. Well, maybe more than slightly. I doubt I’ll play it again, but I think the logic I used around the drum beats will definitely be refined and reused.

In the spirit of the con, the fugly, un-clean code is below the cut, along with some explanation of what the heck is going on. When I say ugly and unclean, I really, really mean it.

Shot

Every other week, I have to give myself an injection of testosterone. I find it really hard to actually pierce my flesh with a needle. It’s like stabbing myself. At the same time, having testosterone in my body is crucial to my identity.

About a month ago, I used a small digital camera and apple’s photobooth software to film myself from either side, trying to do the shot. The pressure was intense. The shot went terribly wrong. It took me forever to work up the nerve to actually push in the needle and when I did, I didn’t push it in far enough. The testosterone leaked back out of my leg through the puncture.

I created a soundtrack to this disaster using SuperCollider. The sound sources are my voice and de-tuned sine wave generators. The left and the right channels differ by 10 Hz. The sine waves move along a tuning lattice but with so much imprecision that the lattice becomes meaningless. Their timing is out of synch. Finally, a clock ticking sound comes in. How long has this been going on? How long have I been sitting here holding my needle? How long is this going to take me? How many more times will I have to go through with this?

Until the end of my life.

The video is created with Processing.org. Every time a new sound starts, the picture updates, but with a a lot of transparency, so time bleeds together and the images become blurry. I’d hoped that through the repetition of images that I experienced in making this piece, that doing the shot would become demystified and I would exorcise my demons. Did it work? I’ll tell you in two weeks.
