What is noise reduction?<\/h2>\n

\"noise<\/p>\n

Noise reduction is a function that analyzes voice data (signals) and reduces \/ removes only constant-level noise components, such as constantly generated ambient noise, making it easier to recognize signals. Sometimes abbreviated as NR.<\/p>\n

\"Noise<\/p>\n

First, the noise is the “sir” or “cut” sound generated by tape media such as cassette tapes, the low “boom” sound that comes from the power supply, the clip noise that the volume of input is too high and the sound breaks and the microphone There is a loud noise that is picked up by. If such noise is included in the audio data, the playback quality will deteriorate, so the function to eliminate it is noise reduction.<\/p>\n

When cutting the mixed noise in the recorded audio data, if the noise level to be cut becomes too high, it will adversely affect the non-noise audio data. Therefore, when performing noise cutting, a technology is required to extract only the noise component from the audio data.<\/p>\n

A typical example of noise reduction in audio is a method of reducing the hiss noise generated by a recorder while compensating for the frequency characteristics as a whole by boosting high frequencies during recording and attenuating high frequencies during playback, and so on. successively. In addition, a dynamic range compression \/ expansion method has also appeared that compresses and records the amplitude of the signal in the part of the recorder with the best S \/ N ratio and expands the amplitude during playback.<\/p>\n

LiveOn noise reduction function
\nEven in a web conference, the microphone can pick up various noises that are not conference related, such as the sound of the air conditioner and the sound of the projector operating, as well as the voice of the person speaking. That noise can also make it difficult to communicate smoothly in meetings.<\/p>\n

LiveOn is equipped with a noise reduction function and it is possible to reduce 50Hz, 75Hz, 100Hz, 150Hz, 200Hz, 250Hz or less from the Preferences \/ Audio tab for each client. This reduces nuisance noises, such as driving noise from air conditioners and projectors, which are detrimental to meetings, and enables web conferencing with a clear, easy-to-hear voice.<\/p>\n","protected":false},"excerpt":{"rendered":"
