Today the cosmOcosm Sound Planetarium had its first demonstration at the UCSD Summer Research Conference. Jake, Yuka & Melisa set up our demonstration rig in the oversized meeting room we were assigned in the afternoon, which piqued quite a bit of interest among the audience members. They’d have to wait; we were last on the docket:
Fortunately the set up is pretty compact and fits in ye olde beach trolley:
Here’s the system set up off to the side of the room: 3 speakers on chairs close to the ground, 3 up high on stools; the area is about a 10′ diameter circle.
This being a conference, Jake, Yuka & Melisa first gave a 15 minute talk about the motivation, design and testing of the test rig…
… which included a nice audio demonstration of audio timbre…
… and a healthy dose of stellar astrophysics
Here’s the presentation slides:
Then we were ready for the demonstration. With Jake & Yuka at the steering wheel, we brought the audience over to experience the sounds of stars by playing the 10 brightest stars in the Bright Star Catalog, with speeded-up nightly transits as they would be heard from San Diego in August.
Here’s the perspective from the audience, where you can hear the stars passing by:
In addition to our 10 star transit demo, we also ran the 100-star fixed demo (actually just 90 to remove the rather seriously loud Sirius), bringing stars in 10 at a time. Here’s a video showing Jake manipulating the interface while Melisa describe a little more detail about how we mapped data to moving sound:
All-in-all, and amazing success! To be able to set up the hardware and run a demonstration in an arbitrary space, we clearly have proven that this is a portal, accessible system. Now we just need more time to play….
Here’s the happy team after a job well done (we’re missing you Tara!!)
