Hi. Gina Collecchia here. Here's a list of the ChucK files I used to sonify my data sets (yes, sets!).
squarepusher.ck
aphex.ck
deadmau5.ck
skrillex.ck
m220a-DataReader.ck
You need to have these sounds in a folder named "sounds"
sounds.zip
in order to run the ChucK files, and this pile of data!
data.zip

Listen to the output here. I also recorded one without effects here.

I got my data from Google Trends. You can enter a search term and get time-series data for how often it was typed into Google every week since January 1, 2004. It gives popularity as a rating from 0 to 100, where 100 is like the best week ever for that guy; basically, it's normalization, but it's not a requirement that it ever hits zero. I entered "squarepusher", "aphex twin", "deadmau5", and "skrillex" and saved them as 4 separate data files. Here's a link to the Aphex Twin Google Trend.

The data sonification is pretty darn simple: I map the amplitude of Artist A's dataset to the amplitude of (0.26-second chunks of) the Artist A's song (using SndBuf). The louder the song in the mix, the more popular the artist from 2004-2012. Skrillex wasn't very popular from 2004-2010 (he was 16), but Aphex Twin maintains energy throughout.

I did this so that I could really "hear" the data, and experience its meaning in an explicit way. I did not normalize any of the WAVE files because I wanted to capture how loudness has changed over the years (the Squarepusher and Aphex Twin tracks are from the mid-1990s). The Squarepusher track has a high-pass filter, the Aphex Twin some Chowning reverb, the Deadmau5 some echo, and the Skrillex a tiny bit of Chorus. I thought these might make it easier to pick out which was which, but actually prefer the effect-less track.

Enjoy!
