Acoustic Kitty, an American Spy - The Atlantic
▻http://www.theatlantic.com/technology/archive/2015/06/acoustic-kitty-technological-history-of-american-espionage/396728

My favorite story about American spying is one I’ve never been able to verify with the Central Intelligence Agency, and not for lack of trying.

At the height of the Cold War, the story goes, officials in the United States hatched a covert plan to keep tabs on Russians in Washington, D.C. They would, they decided, deploy surveillance cats—yes, actual cats surgically implanted with microphones and radio transmitters—to slip by security and eavesdrop on activity at the Soviet Embassy. The project went by the thinly disguised code name “#Acoustic_Kitty.”

“They slit the cat open, put batteries in him, wired him up,” said Victor Marchetti, who was an executive assistant to the director of the CIA in the 1960s, according to an account in Jeffrey Richelson’s 2001 book, The Wizards of Langley. “The tail was used as an antenna. They made a monstrosity.”

A whiskered, yowling, unbelievably expensive monstrosity. The agency poured some $10 million into designing, operating on, and training the first Acoustic Kitty, according to several accounts.

When it came time for the inaugural mission, CIA agents released their rookie agent from the back of a nondescript van and watched eagerly as he set out on his mission. Acoustic Kitty dashed off toward the embassy, making it all of 10 feet before he was unceremoniously struck by a passing taxi and killed.

Eavesdropping on Ecosystems

Sueur and his colleagues weren’t interested in exactly which species were calling. Instead, he says they wanted “to take a global measure of the acoustic output of the community.” Their goal was an algorithm that could boil hours of acoustic data down to a single number describing how an ecosystem’s acoustic energy is distributed across the frequency spectrum and over time.

The boom in sound-recording studies poses a challenge familiar in other fields: a glut of data. Pijanowsky’s lab alone has amassed about 85 terabytes of sound—more than 100,000 hours—in just 5 years. “This is a science that’s plagued by the big data challenges that you see in, say, genetics,” he says. Many researchers already have libraries of field recordings that, if played in real time, would be longer than their careers. “We know that we’re not going to be able to listen to it all,” says computer scientist Michael Towsey of the Queensland University of Technology in Brisbane, Australia.

To get around that problem, he’s developing ways to navigate soundscapes by sight, creating color-coded spectrograms that trained eyes can interpret at a glance. Towsey describes the visualizations as “#acoustic_weather” charts. Some show how the spectrum of sounds shifts over a single day, while others assemble daily records into long-term snapshots to capture changes between seasons or years. That’s akin to studying the “#acoustic_climate,” he notes. And “when we start thinking about the acoustic climate, then we can start thinking about acoustic climate change.” Year-to-year comparisons could eventually highlight subtle and potentially problematic changes, he predicts, such as changing rain patterns or shifts in bird activity.

Computer scientist Michael Towsey combines 8 months of continuous recordings at a research station in Brisbane, Australia, into a single image. Colors indicate different acoustic indices. At dawn (left curve), a morning bird chorus (blue) is obvious during the Australian spring and early summer (October through December), but fades later in the year. Horizontal green streaks indicate heavy rainfall in January and February. At dusk (right curve), cicada activity is evident in the spring and summer months (green); by winter, the night is increasingly silent.
