A technology startup based in San Francisco has introduced a new artificial intelligence-powered device that it claims can prevent nearby microphones from recording conversations. The device, called Spectre I, is designed as a portable tabletop anti-surveillance tool and is currently available for pre-order, with shipping expected to begin later in 2026.
The device is being developed by a company called Deveillance. According to the company, Spectre I can stop microphones within its range from capturing clear audio by emitting power-efficient omnidirectional signals. These signals are said to be inaudible to humans but capable of distorting audio recordings made by nearby devices.
The announcement was first noticed by a technology publication after the company’s CEO, Aida Baradari, introduced the device in a post on X, previously known as Twitter. She described Spectre I as “the first smart device to stop unwanted audio recording.” While audio jamming devices already exist, the company claims its product stands out due to its portable design, use of AI to detect microphones, and efficient audio-jamming technology.
Spectre I is said to work within a range of 2m. Within this distance, the device reportedly blocks microphones attempting to record sound by using omnidirectional signal jamming. Although the company has not shared the technical details behind the process, it states that the device “emits an inaudible signal that makes every microphone within range unable to capture intelligible audio.” This suggests the technology may rely on ultrasound frequencies.
The company also claims that the device can “detects nearby microphones, logs them, and provides you with this data.” Deveillance mentions that the product uses “novel AI, physics, and signal processing technology,” but it does not provide further explanation of how these systems operate.
Additionally, the startup has not clarified possible limitations of the device. For instance, it does not specify whether Spectre I can detect or block recording devices such as dictaphones, wired microphones, or smartphones operating in aeroplane mode.
According to the company, the device aims to help users protect their privacy. It claims the product could prevent companies from secretly listening to conversations for targeted advertising and could also help in situations involving corporate espionage or organised surveillance.
However, the company has not presented any proof-of-concept demonstrations or independent third-party verification to support these claims.
Spectre I is currently available for pre-order at $1,199 or Rs. 1,14,482. The company says the deposit is refundable, and it plans to begin shipping the device in the second half of 2026.
