Sun Spot Data Sonification

photonal's picture

The sonification of the sun spot observation data was created by parsing the data using Quartz Composer (which also provides the visual feedback). The data was also streamed into Kyma and mapped onto audio parameters.

[Data Source: http://tracer.uc3m.es/tws/TimeSeriesWeb/repo.html] utilising Kyma, Quartz Composer and OSCulator.

Should also mention: The data is driven in two ways: Manually with the mouse, so that the X-Mouse position is picked up and is used to index through the data ad hoc or via a Sawtooth LFO which cycles through data sequentially at a rate of 'cycle'.

What tool did you use to capture this video?

I just had a play with a few (screenflow, snap pro, capture me) and none worked

Cheers James

Re: Sun Spot Data Sonification

Syphon Recorder might work for you.

Am using Snapz Pro X (v.2.3.1).

Re: Sun Spot Data Sonification

Just given that a quick run through - Snapz Pro that is and I find it to be way better at creating audio video captures from SBArt4 than Screenium currently is. Great little sonification, BTW :-). Wish I'd known / realised earlier just how well Snapz Pro worked, however, maybe Screenium will ramp up their product to be as effective in Lion as it was found by me to be in earlier editions of OS X.

Re: Sun Spot Data Sonification

I'd like to capture other windows and the viewer input params (like in the above video) so can't use syphon.

How do you get snapz pro x to work? I've only got the trial but when I start it it just locks the screen including QC. I can't even get it to record a movie as after I've set the capture area and press the hot key (the only way I can figure to capture) it just buzz's at me.

Are you using lion? as I have the same version of snapz pro

Re: Sun Spot Data Sonification

So you can not only use it under lion but you like it? it seems like a horrible program but maybe that's only because I can't get it to work but I think its more than that.

The thing that drives me crazy is that I can't get back to my desktop when the program is open - that and the unintuitive interface or am I just missing something?

Like anything else - is easy to use once you know how.

1) Hit your hotkeys to trigger Snapz and set your screen area for capture (screen will look/appear locked at this point) - the area for capture will have marching ants around it.

2) Double click the area within the marching ants to begin capture. (Clicking outside of the marching ants area will move the capture target area.)

3) Hit the hotkeys again to end capture and save the captured data to file.

btw, thought you might like to know that the sound used for the Sonification is a PacMan 'EatOpen' sample lol [manipulated in the Kyma software.]

Actually, Screenium works not as well as it ought to in Lion.

Snapz Pro captures, best to one's main HDD BTW, more efficiently at present than does Screenium in regards of audio video capture in Lion.

As is obvious in the little movie attached below .. :-)

The second, larger movie is a screen capture, no post processing done, wherein the video is producing audio from the near real time rendered Core Image filter, animated against a time input. Arbitrary changes to the actual binary and unary operators affects the graphic resulting and the audio thus created, point is, I was able to get to my desktop, other applications, so long as I didn't interfere with the capture area.

Re: Sun Spot Data Sonification

Double click hey - surprised I didn't try it in my frustration, guess I figured I'd left windows behind

Thanks for the help

Oh that helps me see the pattern: there's a sunspot peak every year that Blinky, Pinky, Inky or Clyde passes over a power pellet.
