Deveillance Unveils AI-Powered Microphone Jammer Spectre I

Deveillance, a startup founded by recent Harvard graduate Aida Baradari, has announced a new device designed to counter unauthorized audio recording by microphones in public and private spaces.

The company’s first product, Spectre I, is a portable jammer that combines ultrasonic emitters with artificial intelligence to detect and interfere with nearby microphones. According to Deveillance, the device is intended to garble speech and prevent automatic speech recognition systems from capturing conversations.

Spectre I is claimed to scan for microphones within a range of approximately two meters and emit signals that are inaudible to most people, but which disrupt the ability of recording devices to capture intelligible speech. Deveillance stated that all detection and signal generation processes occur locally on the device, without uploading data to the cloud.

While the company has opened pre-orders for Spectre I with a deposit of about $1,199, the device is still in development and its effectiveness has not been conclusively demonstrated. Short video clips shared by the founder show the device in operation, but these have not provided definitive evidence of its capabilities.

What the numbers show

• Spectre I is expected to be available for shipment in the second half of 2026
• The pre-order deposit is set at approximately $1,199
• A social media post about Spectre I received over 3.6 million views in just over a day

Existing ultrasonic microphone jammers have been available for decades, often as bulkier and less expensive devices that can be purchased online or assembled using do-it-yourself kits. Spectre I currently produces an audible hum during operation, though Deveillance aims to make future versions silent.

Some experts have stated that reliable detection of microphones using radio frequency or Bluetooth signals is limited, and that effective detection would represent a new development if achieved. Critics, including security researchers such as John Scott-Railton, have said that Spectre I’s claims have not yet been substantiated and that similar devices are already sold at lower prices online.

There is also discussion regarding the scope of Spectre I’s detection capabilities. Some critics have argued that the device may only be able to identify Bluetooth or Wi-Fi audio devices, rather than all types of microphones. Ultrasonic frequencies used by the device may also affect pets or people who are sensitive to those sounds, and further testing is required to assess these effects.

As of now, Spectre I remains in the development phase, with limited public evidence supporting its effectiveness in real-world scenarios. Deveillance continues to promote the device as a privacy tool, while feedback from security researchers and the broader technology community highlights the need for additional independent testing and verification.
