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.
The explanation isn't satisfying
