Remote.js is a super slick way to wirelessly communicate between devices without the use of additional hardware or a middle man. Instead it relies on tones: Applications can communicate with one another by literally emitting tones at different frequencies. The receiving computer listens for that tone (via standard microphone input) and then reacts accordingly. No web sockets, nodejs, or any other middle man required.
Sweet idea, but not a very new one. See http://en.wikipedia.org/wiki/Tone_remote
Nevertheless, it brings up good memories from the dial-up modem era. A nice article about it: https://medium.com/people-gadgets/3d43eac5f1de and http://www.windytan.com/2012/11/the-sound-of-dialup-pictured.html
Interesting. Is this the same tech behind Steve Wozniak’s Blue Box? In the comments I found this even cooler lib – SONICNET.JS : http://smus.com/ultrasonic-networking/
I’m also wondering if Square reader is based on similar princple using sound wave:
