Anti microphone recording countermeasures.
The anti recording countermeasures device is state of the art & unique in all respects. During active operation, the device masks audio, like voice conversations, in the room or car. So, smartphones and digital recorders cannot record your voice. Moreover, the device disrupts digital microphones, disabling them from recording sound.
Unique anti recording countermeasures.
Oscillating white noise generated at a particular ultrasonic frequency emits from the device in stealth mode. Very low white noise audio is present when operating in stealth mode. The ultrasonic noise disables any recorder’s microphone from functioning. The audio nullifying device does not break any radio licensing law in the UK or EU.
The recording countermeasures device protects your audio conversation from eavesdropping devices. It stops spy devices recording, for instance, wireless microphones, tape recorders, and hard-wired microphones. It does not transmit RF radio frequencies and is legal to own and use.
Optimises audio jamming performance.
The transducers point towards the locations of the eavesdropping device, when possible? These types of microphone are found in tape recorders, dictaphones, and microphones, for example. The Ultrasonic countermeasures device protects you from hidden recorders.
Operating the aiti spy device.
Make sure the device is facing outwards from the direction of your speech. The optimal distance recommended from the transducers output to the microphone of the suspected eavesdropping device is 2 metres.
Switch on the device and adjust the volume of the acoustic signal, so that you can still hear the person you are talking to. It would help if you held your conversation at a slightly lower voice than usual. If you feel the threat represents a full response, turn on TURBO mode for more effective jamming of any hidden microphone.

I tested the device with a few different phones and voice recording products. Its works better with the extra surround speaker. Performance is increased two time at least, better for me. I would recommend this product.
