Tomek Rękawek, irritated by ads on the radio, created an app that mutes them. Radio Adblock uses digital signal processing to detect distinctive audio patterns that signal the beginning and end of breaks. (via Hacker News)
I also prepared a simple standalone version of the analyzer, that connects to the Trójka stream on its own (without an external ffmpeg) and plays the result using javax.sound. The whole thing is a single JAR file and contains a basic start/stop UI. It can be downloaded here: radioblock.jar. If you feel uneasy about running a foreign JAR on your machine (like you should do), all the sources can be found on my GitHub. Apparently, it works :)
To make it work universally, perhaps DSP could detect the use of extreme waveform compression. This makes ads sound as loud as possible without increasing the signal volume, and is a technique that advertisers and radio stations supposedly use to skirt the regulations that forbid them from doing just that. It would also have the bonus of silencing shitty pop songs.
Second Chance is a smartphone app developed by University of Washington engineers to detect an opioid overdose. The researchers tested the app at a public supervised injection facility in Vancouver, Canada with encouraging results. From Science News: Second Chance, described online January 9 in Science Translational Medicine, converts a smartphone’s speaker and microphone into a […]
Most software, writes Ink & Switch, is slow. Slow Software works as a FAQ about all the reasons this is the case, from input latency to inefficient design.
Pixelmash is clever indeed: create your resolution-independent art with the same freeform speed as you might in any other painting app, then let it nondestructively pixelize it, with 1-pixel outlines, adjustable gradients and dithering. Pixelmash’s resolution-independence lets you do really cool things… Like create animations using layer transforms rather than having to paint every frame […]
There’s a reason you’re hearing about the gig economy in every other business story these days. More than ever, people are finding income from more than one source. And if you find the right one, a side hustle can do more than just pad your pockets – it can allow you to finally get paid […]
High-def cameras are available to anyone and for much less than they were just a decade ago. Even the phones in our pockets can be used to shoot and edit short films. It’s never been easier to be a filmmaker, providing you have the technique. Enter the Film & Cinematography Mastery Bundle, an online boot […]
Breaking into the indie video game market may be easier than you think. It all starts with an idea, and then it’s a matter of finding the right development platform to bring it to life. No matter what that platform is, it’s a good bet that it’s covered in the 2019 Game Dev & Design […]
