I have noticed a strange interference triggered by physical movement when recording vinyl to the pc, the noise is not there until I drop the needle onto the record, as soon as I do that every time I move, not walking across the room or even touching the floor or anything to cause any vibration but just by sitting in a chair and moving my arm a few inches a strange noise comes through the right channel as you can hear in the clip I have uploaded here http://www.divshare.com/download/23782915-d10 I have a technics SL1200 going into an Art DJ preII pre-amp then into the pc line in. I have tried different bitrates etc on the line in but it's always there, when I plug the pre-amp straight into the stereo (not via the pc) there is no noise caused by me moving so I know it is something to do with the pc but what I don't understand is how this noise occurs by me just moving my hand a few inches??? Why is it only when the needle is sat on the record this happens and how the hell is it picking up these small movements without me touching anything? I eliminated it being my mobile phone I switched that off and moved it to another room, checked the ground connection to the pre amp which is ok but the strange noise is still there. There is a good few feet between the turntable / pre amp and the pc. Can somebody shed any light as I want to get rid of this annoying noise as it is coming through on quiet parts of the songs and between tracks.
