With the development of information society, audio and video information is characterized by explosive growth and viral transmission. Personal privacy, trade secrets and other information are at risk of being leaked through conversation, especially those valuable conversation information. How to protect the conversation content from being obtained by others

The working principle of mdpb-l7s is to emit ultrasound with random noise that cannot be perceived by human ears. When recording with digital devices such as mobile phones, these noise and normal conversation sound are recorded into the digital devices, making the recorded audio invalid. It also has the same interference effect on the audio information in the captured video, Because the noise with ultrasonic noise is generated randomly and cannot be restored, the audio after being disturbed cannot be restored, so as to ensure that the original information is not leaked and transmitted.

When you want a safe conversation space, whether it's a company meeting, a conversation with old friends or a conversation at the dinner table, but you don't want the conversation to be leaked or made public, a recording shield can help you. You just need to turn on the switch button, and the recording shield will send out harmless ultrasonic waves that exceed the threshold of human hearing. Using our self-developed ultrasonic noise algorithm, the microphones in digital devices such as mobile phones and recording pens will be affected by the anti recorder, which will drown the sound of normal conversation in random noise, and it is difficult to restore the recording post-processing algorithm, So as to protect the conversation from being leaked from the source
