Show HN: Mofi – Content-aware fill for audio to change a song to any duration
I worked on a web service that allows you to import a song and define a target length that the song will be shortened or lengthened to. It does this by analyzing the song and finding repeating audio patterns. This is helpful for making any song match a video or performance with a set duration. You can also specify areas of the song to prefer or avoid. An example is available here: <a href="https://mofi.loud.red/edit/8bd3fdf780f8c3927e41029f3b957f8a7ed96863" rel="nofollow noreferrer">https://mofi.loud.red/edit/8bd3fdf780f8c3927e41029f3b957f8a7...</a><p>The cool thing is that after the song is analyzed on the server, the client can recompute and preview the results completely client-side through an implementation that uses Web Workers and WebAssembly. The audio previewing uses Tone.js. I am thinking of writing up some more details about the implementation in the future.<p>I'm still working on a way to explain this easily, but I like the idea of carrying over the concept of content-aware fill from images to audio.<p>Please let me know if you have any comments or questions!

Discovering that a Bluetooth car battery monitor is siphoning location data
Hi HN, this is my efforts in reverse engineering a BLE car battery monitor where it's app has over 100,000 downloads on the Google Play store alone.<p>It turns out it's sending GPS, cell phone tower cell IDs and Wifi beacon data to servers in Hong Kong and mainland China on a continued basis. Google and Apple app store pages say no personal data is collected or sent to 3rd parties.<p>Hopefully readers pick up a few tips on reversing apps for their connected devices.
