I've done about 4 years of research on sonification, which is using non-speech audio to represent patterns in data ( http://mags.acm.org/interactions/20120102/?pg=37#pg37 for some specifics). This article is a subset of sonification in some ways, since we're representing some quantitative data using auditory parameters. There's an entire class of scenarios where conventional HCIs can't represent data for analysis: wh…

No doubt. Years ago, a buddy hosted corporate email, dns, etc. Racks of servers. He added ambient audio to everything he monitored. Nature sounds, weather, birds, insects, etc. The volume, samples, and tempo would change dynamically. Happy soothing sounds when all was well. Disruptive sounds when bad stuff happened. (I don't know if you'd classify that as sonification.) Walking around, visiting with guests, talking o…

Yep, exactly - applications like that are just cool, useful and intuitive all at once.

What's interesting is that for visual displays, we have decades of detailed research into visual perception - we know from experience how to design a graph so that patterns can be quickly extracted and understood. We don't yet have that same level of understanding for sonifications, but once we do, applications like this will be even better

Can't play the audio today because of the snow - I use a satellite internet, so I can't comment on the music, sorry. I trade though, and I also compose, so this project got my attention. What I'd like to add is this: My focus on trade in this period is penny stocks. From my own experiences and what others say, I can say Apple and other blue chips usually don't move as "dramatically" as much cheaper penny stocks. It's in the math. If a current price is in the $500 range, like Apple, changes of a few $s only represent less than 1%, whereas in penny or sub- penny stocks, a single trade can move the price up or down a few pennies or less that can easily amount to 10, 30 or bigger % change. Movements like that going back and forth within very short period sometimes resemble needle-sharp alien teeth, it's funny to watch. Price % changes are that much crazier, and likewise the volumes when a stock suddenly gets attentions etc. I'd imagine that music generated off that kind of data can present different kinds of compositional experiences.

lol You've succeeded. Well it sounds awful. Just the way dubstep does. For your next project try using "paul stretch" to create a serene ambient track. It's software that allows you to stretch audio tracks from 101% to 800% and up. Here's Justin Bieber's song "U Smile" 800% slower http://www.youtube.com/watch?v=QspuCt1FM9M You could use all sorts of data to make ambient music. Heck, call it Ambient Data and release n…

I imagine it can be automated. Sources can be any moving data be it weather, market, stats, transcoded visuals, medical signals, etc, and can be output in any media for different purposes. Speed can be variable and programmable along with timbre, ADSR tone shapes and spectra et al ala some sound-shaping programs in the market. Knowledge got2surf presented can be applied.
