I'm with the sceptics, but also they don't show it in use. But from the product screenshot of the person hitting the button, it seems not to be wearable, so.....when would I use this? When I'm in a room that has a smart-speaker? So I go to a friends place for dinner and I put this device on the table so that my friends Alexa can't hear me.

Good thing I wore my tin-foil hat to dinner, but sadly, my friend didn't wear one, and now they can't get a timer for their cooking and the meal is ruined. Brilliant.

Let me tell you about my rock that keeps tigers away…

This seems like product spam.

The explanation isn't satisfying

>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.

Assuming 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.

I 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.

No proof of their claims of it working? Sounds like snake oil.

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.

> Detects nearby microphones

This part seems like BS.

> creates a 2m protection zone around you. It sends out signals that are inaudible to you but can be detected by a microphone

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.

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