A noise and interferences generators is a device able to prevents the operation of microphones on recorders, mobile phones and other similar devices. For instance the OMNI-JAM, is an high performances anti-recording device, has a 360 deg. operating range. Thanks to the microphone inhibiting signals emitted by the device, specifically randomized by a modular algorithm, people inside the operating area cannot be heard. In this way any kind of audio spying attempt is ineffective.
