The Nikon ME-1 Stereo Microphone w/ Wind Screen and Soft Case is an advanced device for recording crystal-clear sound. This microphone uses one of the advanced technologies to significantly reduce the autofocus noise on your Nikon digital camera when you are recording. This stereo microphone connects to most cameras and is compatible with DSLR, Nikon 1 and COOLPIX cameras that have a 3.5mm Mic jack. The cable stop feature helps in holding the cable and preventing it from accidentally bumping into contact with the cable, which might make noise being recorded. Another important feature is the low-cut filter that helps in preventing the wind noise and other low-frequency noise that are not obstructed by the wind screen.
The signal to noise ratio (SNR) is a useful and universal way of comparing the relative amounts of signal and noise for any electronic system; high ratios will have very little visible noise whereas the opposite is true for low ratios.
