Despite being rather ear-piercing each time a Chirp was sent, it was still a very interesting principal. I remember reverse engineering the protocol and error correction mechanisms (it was a varient of the Reed-Solomon algorithm iirc) with a friend for a little household &amp;quot;internet of things&amp;quot; that communicated over sound.

I&amp;#x27;ve been playing around myself recently with implementing a simple data-over-sound protocol (nowhere near as advanced as Quiet). If anyone is interested, here is a quick 1 min showcase: &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;watch?v=HrMQjFGD_MU&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;watch?v=HrMQjFGD_MU&lt;/a&gt;</text><parent_chain><item><author>joshumax</author><text>For those of you interested, there was an app called Chirp by Animal Systems that allowed you to transfer messages and shortcodes of hosted media content over audible frequencies.
