Experimental music from very short C programs

category: code [glöplog]
Whipped together a 128 byte implementation of the first one for the Atari VCS in about 30 minutes. Due to the TIA being what it is, the output is limited to 5-bit PCM. Check it out:
Binary - works fine in Ubuntu's Stella and probably on the real thing, but not in the Windows version of Stella (it doesn't like programs omitting VSYNC)

I thought that the demoscene is all about niche bullshit.

one line of code

some crap music

oh well, wasted 5mins at work ;)))

A message to Viznut and his noize-generator ref. http://countercomplex.blogspot.com/2011/06/16-byte-frontier-extreme-results-from .html. nice try! but i have a noize-generator that takes 13 bytes.

actuall, i see that there are 4 bytes for the actual random generation routine, which is the same amount of bytes i have in mine. if anyone ever manage to reduce this to 3 bytes, i will buy you a beer!

ooh hey. One of those one-liners is attributed to a "visy."

...Maybe it's our visy?

Oh, hello there.

I'm a little bit surprised that this video has already gathered 3500+ views in less than two days and has inspired people far beyond the demoscene to try something similar. Perhaps it was a good idea to publicize some unpolished preliminary experiments (blame Visy who originally shared the code fragments on Google+ the day after we played around with them on IRC).

One potentially fruitful path of future exploration would be softsynths that combine semi-chaotic math with some deliberately chosen synth functions. This would ideally allow for dramatically size-reduced executable songs that still sound good. Also, the same functions that generate rhythms and musical structures for a song could also be used to drive various parameters in visual effects. This could lead to e.g. <=256-byters with a lot of interesting audiovisual variance.
i was wrong, this is actually a bit fun.

MidKnight: yes, it is indeed I.

if you *really* want to dig into such music, I found it handy, to use that site here, that fills the waveout with javascript.

That means, you can build up a sine there and have full open source and can get the codes you need (for example for a a sqare or sabretooth sine)


in the end I turned back to 4klang :)

Found this on twitter:


Online version to play with it :D

20 byte symphony for c64. type this into your hex editor:

Oh the headaches.

Nystep: great one, sound like Dig Dug arcade game :)
great stuff!

my try:

(t*(t>>8|t>>9)&46&t>>8)*4|(t&t>>13|t>> 6)

I call it "Lost in Space"

And a small program for testing with BASS: http://pastebin.com/MRyf472f

Cool stuff!

You can use inequalities to script in changes to the beat (even though that's kinda cheating).

My first attempt:
((t>>t%24>>t%12<<t%6)|t>>30)-4*sin(.2*t)-(t>65300)* 5000*cos(0.001*t)

Sure, it wasn't the intended purpose, but...

Can you guess where this is from?

((t%40000)<5000)*(t%(8000/392))+((t%40000)>7000)*((t%40000)<12000)*(( t%40000)%(8000/523))+((t%40000)>14000)*((t%40000)<19000)*(t%(8000/555))+((t %40000)>21000)*((t%40000)<26000)*(t%(8000/420))
