Hi, I got the same thing with Samsung G-track device. I replaced its USB cable for another one and it corrected the thing. You can also try to lower sample rate and see if it helps a little. I believe, I saw on Google something about some USB mic with special feature to reduce/eliminate any noise generated by its USB cable but cannot recall the name of this mic. Best, Pawel.

I just bought a griffin imic which I'm using on my windows xp machine. It is working wel as far as playback, but when I try to record using a microphone I get a lot of background whine which sounds like it might be coming through the usb port. I have the mic gain adjustment turned all the way up. Here's a link to a sample. http://dl.dropbox.com/u/5297006/imictest.mp3 I'm using an audiotechnica modelat8004 dynamic omnidirectional microphone which has a sensitivity rating of -49 db and impedance of 600 ohms. Do you have any idea what might be causing this noise. The imic is plutged into one of the usb ports on my audigy sound card. I also tried it on one of the pc usb ports on the bcak of the pc with the same results. To unsubscribe from this list, send a blank email to: pc-audio-unsubscr...@pc-audio.org
