Holophonic sound is an audio recording technique which operates on a principle similar to Holography. The result has been reported to be realistic and life-like three dimensional sounding audio recordings.

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.

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]

Engadget points out Sven König's Scrambled Hackz, an Ableton Live-like app that takes in sound samples, analyzes their spectrum, and builds a triggerable, interactive beatbox set upon which hilarious and remarkable performances can be built. A GPLed package will be released soon.

A world of sounds. Despite their difficult URL, The Freesound Project has grown at a rapid pace over the last year, arguably surpassing archive.org's audio library when it comes to sound effects, field recordings, site design, and usability. Now Freesound is combining their sound library with geotagging and Google Maps, allowing users to navigate the world by sound too! (previously on mefi)

Would you pay $9000 for speaker cables? No? Ok, how about $11,700? These are just a few of the seemingly overpriced audio components listed on this page.

Henry Jacobs is, a unique and mostly forgotten (but recently reissued) sound artist and humorist, an inventor of surround sound and, apparently, really really good at left handed ping-pong.

DIY Guide to Recording. Set up a home studio. This seems to cover a lot, and not being a pro at audio recording, I found it pretty useful.

If listening to sound of different languages is something you may be interested in, visit the multimedia language project website hosted by the Martin Luther University of Halle-Wittenberg. It features the sound files of a small blurb from Saint-Exupéry's The Little Prince read outloud in a 100 different languages. The blurbs are also textually transcribed. [See more inside]

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.

Live improvisation with digital audio. Play, loop and compose with multiple sound file formats, including: wav, aif, aiff, aifc, mov, au, mid, mp3, swa, mpg, mpeg, snd... Found while Googlifying for links to the currently tanked Johnny Spencer's 'vanity site' directed towards fans of Black popular music c1940's to 1970's. I have not a clue as to the what or why of it but thought the teeming geeky horde might. Provided for your consumer testing.

Audio spotlight directs sound as precisely as, well, a spotlight What an amazing idea, although as the article says "Most of the uses of sound involve spreading it around."

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.
