>What is Spectre I and how does it work?
Spectre I is a portable audio security device that creates a 2m protection zone around you. It sends out signals that are inaudible to you but can be detected by a microphone. Through customization of the signals to match the human voice, your conversations are "overlayed" when a microphone receives them. It uses local processing to prevent nearby smartphones, smart speakers, and other devices from picking up your voice. Everything happens locally on the device — nothing is sent to the cloud.
It's unclear whether it performs the task or if it's illegal, similar to a phone jammer.

Phone jammers are illegal because they are broadcasting into regulated spectrum. There is no such spectrum regulation around audio transmissions. I will not say one way or another if this device actually works as adertised, but particularly if the signal is outside the range normally audible to people there should be nothing illegal about this device.

How can it detect nearby microphones?
Also, seems like your voice would easily project farther than 2 meters, the "protection zone" of this device. That's not even the size of a room.

#5Please just show me a single clear image of the entire product.

You're right about FCC laws, but there are non-FCC laws, too, such as penalties for willful interference with federal/state emergency communications.
I'm wondering if this device would cause issues for a nearby person's emergency communications. Seems potentially really bad.

#7Assuming this is not a scam, my guess is that it emits sound above the Nyquist frequency of mic'ed devices with the hope that they lack a low-pass filter on the input of their ADC. Such devices would then suffer sample aliasing that would overlay the high frequency that is output by this device with whatever in-band audio that it intends to obscure. A cheap low-pass filter would defeat this and is likely there in any case in most mic'ed devices as the world has high frequency ambient noise.

This part seems like BS.

Plausible but anything inaudible to you and screwing with the remote is a software or hardware upgrade away. It’s hard to imagine a sw or hw bandpass filter doesn’t stop this. Also hard to imagine smart speakers aren’t doing this already to extract your voice in a noisy environment / personalize responses.
I’d wait for this to be independently verified and understand how they propose to find microphones. Maybe they’re looking for the Wi-Fi / BT signals the speakers are emitting but something like a local nanny cam there’s no way.

#9I can't imagine that mics are going to be affected by anything that doesn't also seriously bother at least some animals, definitely not something I'd use outside of some ultra secure conference room or something.

You seem to be pearl clutching a bit too hard. I am positive there are no legal issues.
