Live visuals for Chris Carlson @ CCRMA Modulations 2012

sorry for the cuttoff at the end -- SD card was full.

this set was essentially more live-coding experiments with non-periodic tiling patterns. I'm still fascinated with the forms. Towards the end of the night I started using color.

visual software done with: audio-shadertoy

for this setup, the live audio was analyzed by ChucK through the built-in mic on my macbook air. the ChucK script routes osc to Node, and the client receives via web sockets.

because osx-style full-screen multi-monitor support is completely broken in OSX Lion, we couldn't use chrome. so we stripped out all the chrome-only webaudioapi stuff, and replaced it with an osc receiver. This allowed us to analyze the audio with an external interface and use any browser that supports webgl canvas, and does multi-monitory fullscreen correctly on osx. we ended up using firefox.

Documentation of the process of installing archlinux and Windows 7 in a dual-boot configuration.

System Specs

• AMD X2 dual-core processor, running at 2.8 ghz, circa 2002
• ASUS ATX motherboard
• 2 gigs of ram
• 100gb drive
• nvidia gtx 550 ti graphics card
• linksys wmp54g wireless pci network card
• 550w power supply

Installing Windows

Windows was installed from a USB stick using Microsoft's Windows 7 USB/DVD tool. It's required to create this key from a Windows 7 system. Boot with the USB drive, then install Windows on the drive in a single partition. Windows also creates a System Reserved partition for itself. Once installed, via Start Menu > Administrative Tools > Computer Management > Disk Manamagent, select 'Shrink Partition' on the main Windows parition to create another partition for Arch. The default value for the shrink is 50%, so for my setup the value for the new disk size was ~50GB, which was ideal.

Note about this install. I have an old Linksys (Cysco) WMP54G Wireless PCI Card. Drivers from Linksys/Cysco's website didn't work, but following this blog post, the generic RALink drivers worked great.

Working with various interfaces that output json or xml results in lots of situations where you have a single-line, unformatted output. Here's a quick way to format json, xml from the CLI.

via the command line:

format json

cat unformatted.json | python -m json.tool

format json from clipboard

pbpaste | python -m json.tool

format xml from clipboard

pbpaste | xmllint --format -

for all above examples, you can pipe back to the clipboard with | pbcopy at the end of the command, or output to a file with > output.json or > output.xml.

Since there is no equivilent to /dev/dsp or /dev/audio on OSX, you need to install an alternative like sox.

Install sox by either downloading the OSX binary from http://sox.sourceforge.net/
or
install homebrew, and then install sox with brew install sox

Examples

cat audio from /dev/urandom/ :

cat /dev/urandom | sox -traw -r44100 -b16 -u - -tcoreaudio

audio from an executable

cat > test.c
main(t) {
  for( t = 0;;t++)
    putchar( t * ((( t >> 12 ) | (t >> 8)) & (63& (t >> 4 ))));
}

gcc test.c -o test
./test | sox -traw -r8000 -b8 -u - -tcoreaudio

Imagine that every man's mind is an island, surrounded by ocean. Each seems isolated, yet in reality all are linked by the bedrock from which they spring. If the ocean were to vanish, that would be the end of the islands. They would all be part of one continent, but their individuality would be gone.

The case of India is particularly instructive. The main difference between us and the British in India was that they had no real motives for going there—no conscious objectives, that is, except such trivial and temporary ones as trade or hostility to other European powers. They found themselves possessors of an empire before they knew what to do with it, and were never really happy until they had got rid of it again.

My dreams have been incredibly vivid. probably due to the heat. sleeping at odd hours. been working in the studio most of the day at Vishal's house, so I haven't been going out as much as I would like. It's also incredibly hot outside, averaging about 36 degrees C, which is about 95 F.
