As an undergraduate I became interested in how timbre can be used to identify musical instruments. This was largely due to my first UROP (undergraduate research gig) with Keith Martin at the MIT Media Lab. Keith’s thesis was on identifying musical instruments from spectral features, and I worked a bit on this under Ryan Rifkin in a later UROP. I’ve been catching up on podcasts during my commute to campus this week, and a semi-recent Science Friday piece on the Steinway factory was on deck for this morning.
The piece talks about work in Agnieszka Roginska‘s lab at NYU, and in particular work from a paper from last year on measuring radiation patterns in piano soundboards. The radiation patterns are pretty but a bit hard to interpret, largely because I’m way out of the acoustical signal processing world. However, what’s interesting to me is that we’re still largely focused on overtones/cepstral coefficients. I wonder about how one might discover more interesting features to characterize this data. (I know someone will suggest deep learning but color me a little skeptical).
As a side note, one of the recent popular articles from JASA is on the acoustics of coffee roasting.
There’s a lot of talk about how the journalism industry is suffering and soon we’re going to be piled under an avalanche of Buzzfeed lists, reblogs of reblogs, doges.
My friend Celeste LeCompte and her friends have started a new venture called Climate Confidential — they are a collective of journalists and writers who will focus on environmental issues. They’re running a crowdfunding campaign on Beacon, a writer-focused site, to get started. I heartily encourage you lurking blog readers out there to support them.
The English version of the Japanese cooking site Cookpad was launched recently. The launch means more lunch for me!
In case you wanted to listen to old African vinyl albums, you’re in luck.
I have a burning-hot hatred of payday loan places, so this Pro Publica piece just stoked the fire.

My friend Amrys worked on the Serendip-o-matic, a tool that may be more useful for those in the humanities than us engineer types, but is pretty darn cool.
Via Inside Higher Ed I saw that Obama has nominated France Anne Córdova as the new head of the NSF. Córdova may be most famous as NASA’s Chief Scientist, but after leaving NASA she had a series of administrative positions, most recently as President of Purdue.
Do any of the readers of the blog have an opinion about this choice? Also, given the GOP’s oft-expressed dislike of the NSF, will she ever get an actual Senate confirmation?

Things seems to be heating up on the LAC. Not a good sign.
The death toll in Dhaka keeps rising. This makes Matthew Yglesias’s reaction (see a stunningly poor example of self-reflection here) a bit more that the usual brand of neoliberal odiousness.

LACMA, which I finally saw with a friend in February, has decided to offer high-resolution downloads of many of the items in its collection. This Ganesha has a pretty impressive belly. Via MeFi.
This may answer David Bowie’s question.
This slideshow makes me want to go to Slurping Turtle again.
Sometimes I wish we could just name p-values something else that is more descriptive. There’s been a fair bit of misunderstanding about them going on lately.
