Hello, first, excuse me but it's very difficult for me to speak or write in english. I'm sorry. My problem : I like to play music, and i like to record the music i played. I record my music with a microphone plug to my MD recorder (sony mz n707 net MD). And after, i like to move the songs i recorded from the minidisc to the computer. 2 solutions : 1) i connect the md phone out to the souncard line-in, and for each songs, i press the md play button and record soundcard line in withe an audio software like cooledit. This solution take a long time for me, but the sound is good. I must just to normalyse the level. But no noise. 2) It's like the first solution Exept i don't press the MD playb button : I connect the MD to the PC with a USB cable an use the sony software or an other md software (winMd record each songs automatically when usb and line is connect). I prefere this solution, but the sound is bad : there is a big noise (no very big but more than the first solution) Do you now this problem? I try to change the USB cable, but the problem stay. Just the line cable between the minidisc and the computer line in : no problem The line cable and the usb cable between the minidisc and the computer : a bad noise. Help me please ....
