The Visual Microphone: Passive Recovery of Sound from Video

Researchers at the MIT Computer Science and Artificial Intelligence Laboratory, Microsoft Research, and Adobe Research have presented a technique for reconstructing an audio signal by analyzing minute vibrations of objects depicted in video. For example, the method can be used to extract intelligible speech from video of a bag of potato chips filmed from 15 feet away through soundproof glass. [more inside]

A Sonic Time Machine

The Roaring Twenties: An Interactive Exploration of the Historical Soundscape of New York City (sound autoplays). via i09, which says The map uses a combination of noise complaints and old reel footage to plot everything from what must have been an exceptionally noisy subway turnstile (complete with notes from the police report) all the way to a carnival barkers in Coney Island, and is a great way to listen in on the everyday life of a New York City gone-by.

Listening to the past, recorded on tin foil and glass, for the first time in over a century

Towards the end of the 1800s, there were three primary American groups competing to invent technology to record and play back audio. Alexander Graham Bell worked with with Charles Sumner Tainter and Chichester Bell in at their Volta Laboratory in Georgetown, Washington, D.C., while Thomas A. Edison worked from his Menlo Park facilities, and Emile Berliner worked in his independent laboratory in his home. To secure the rights to their inventions, the three groups sent samples of their work to the Smithsonian. These recordings became part of the permanent collections, now consisting of 400 of the earliest audio recordings ever made. But knowledge of their contents was limited to old, short descriptions, as the rubber, beeswax, glass, tin foil and brass recording media are fragile, and playback devices might damage the recordings, if such working devices are even available. That is, until a collaborative project with the Library of Congress and Lawrence Berkeley National Laboratory came together to make 2D and 3D optical scanners, capable of visually recording the patterns marked on discs and cylinders, respectively.

Wait Until Dark

Modern mainstream video games tend to be about framerates and millions of polygons per second. But it is possible to play games that have hardly any graphics at all: audio-only games like Papa Sangre, designed for iOS devices, being the most recent example of the genre (and with binaural audio, probably the most ambitious). There are others: In The Pit for Xbox 360 (or a PC with a 360 wired controller) [previously], the (sadly incomplete) Cadet 277 for PC and Mac, and SoundVoyager, released in 2006 for the Nintendo. More at the Experimental Gameplay Project.

All we hear is radio ga ga.

Audiophoolery: Pseudoscience in Consumer Audio. You might think that a science-based field like audio engineering would be immune to the kind of magical thinking we see in other fields. Unfortunately, you would be wrong [...] As a consumerist, it galls me to see people pay thousands of dollars for fancy-looking wire that’s no better than the heavy lamp cord they can buy at any hardware store. Or magic isolation pads and little discs made from exotic hardwood that purport to “improve clarity and reduce listening fatigue,” among other surprising claims. The number of scams based on ignorance of basic audio science grows every day. Via.

Whalesong and ocean sounds

It also has a couple of nice sections on how animals use sounds in the ocean. (Previously.) [more inside]

QuIET is the New Loud

University of Arizona physicists have discovered how to turn single molecules into working transistors. The research could result in much smaller, more powerful computers and other devices with the ability to process many more channels of high-resolution audio and video than current products can manage. The abstract is available in PDF.

No, I'm not sure how they get it to not devolve into a wall of feedback... though that'd be pretty rad too.

A Piano In A Gallery. David Cunningham (the guy behind The Flying Lizards! Wikipedia because the main at-least-quasi-official site's down, but while you wait 16 days for that, why not read this interview with Deborah Lizard for your FL Fix) and his new project... A Piano In A Gallery. No, he's not actually PLAYING the piano -- the visitors are. It's a sort of similar thing to both Brian Eno's gallery work with ambient tape loops on different time cycles, creating an ever-shifting collage of sound and David Byrne's recent Playing The Building. The room is mic'd, and the sound is run through a piano, and amplified, both bringing background noises to the foreground AND creating feedback-style loops, as those sounds are also run into the mics and so forth. So... if you happen to be in London.... [via WFMU]

You are getting sleepy

SBaGen is software (Windows, Mac and Linux) that generates binaural beats - interactions between sound waves that mess with your brain, to induce sleep, relaxation, activity, and allegedly even hallucinogenic states. SBaGen relies on text-file presets (although it comes with dozens of files to experiment with) but if you want a "quick start", there's also the Windows-based Brain Wave Generator.

There's been a lot of talk of late about signal-to-noise ratios here on MeFi (er, Ashcroft who?...). Generally, we think of noise as something that always degrades the quality of a signal. Sometimes, however, the opposite can be the case. Here's a neat little demonstration of a non-linear system in which noise can be used to amplify a signal that would otherwise be too be faint to detect any other way. It exploits a phenomenon known as Stochastic Resonance.
