This "AI powered" microphone jammer is wishful thinking at best, hence the preorder pricetag.

This "AI powered" microphone jammer is wishful thinking at best, hence the preorder pricetag. I have a lot of experience with nUHF trackers and the excellent @kaputnikGo already released the Pilfershush app for #Android that does active (and passive) ultrasonic jamming, as well as another IoT project in the wild. Smart speakers like #Alexa use MEMS and will be quite difficult to jam without radio jamming, not audio jamming, which AFAIK will not be approved in a consumer device (at least in US).

@profdiggity well it looks conceptually feasible. but whether it can be implemented by them and usefully works to its two meter "protection zone" is another thing. Also, only 2m? May as well whisper in someones ear than spend 1200 bucks

@profdiggity also it has very edgelord name - spectre

@kaputnikGo LOL well the whole campaign is clearly a "we'll figure it out when we get the funds" approach.
Don't smart speakers like Alexa also have MEMS in an array around the circular device? How can that be disrupted without an electromagnetic jammer? Seems to me you'd never be able to "aim" the sound anyway even if it were high amplitude
And also, it seems to me a white noise machine on the desk between the speakers is probably more useful.

@kaputnikGo I know you're more on top of all this than me. The most successful pwning approach I've seen is see is "Dolphin Attack": https://github.com/USSLab/DolphinAttack and https://arxiv.org/abs/1708.09537
...but this isn't jamming anyway.

@profdiggity There was a method published years ago that targeted MEMS with UHF audio at around 50k and it would create what they called "shadow bands" that could be used to flood the microphone with noise. Given Spectre's range that might be the method they are using.

@profdiggity it is possible to aim sound, the US police use a device that does that.

@kaputnikGo sure, yes. but that's a bit different than this case in scale and scope. and of course the promise with this sleek mini dome is a "cone of silence" radially around the device.
I know Google Nest does some active beamforming and cancellation stuff to listen for the command/wake words. Even if the physical challenges are solved, I fear the cat-and-mouse game would not last long.
Great to hear from you! hope all is well

@profdiggity it will be interesting to see the device's internals. Been doing great. No more android dev for me though since they started demanding gov ID etc. Hopefully FDroid can weather this madness otherwise I move to my pinephone

@kaputnikGo I've found ubports on Fairphone to be pretty reasonable
