Unless properly shielded any internal card (and cables) are prone to induced interference from the rather audio-hostile world of the computer. Nigel Nigel Bewley British Library Sound Archive -----Original Message----- From: Association for Recorded Sound Discussion List [mailto:[log in to unmask]] On Behalf Of D Basson Sent: 15 September 2005 23:15 To: [log in to unmask] Subject: [ARSCLIST] Reducing soundcard/circuit noise Dear Group members I recently bought a Dell Optiplex GX620 computer with Windows XP. I use a Terratec DMX6Fire soundcard. When I make recordings using Adobe Audition or Wavelab, I get a buzzing noise - a problem I have never had with my previous computer. Can anyone perhaps help me solve the problem?
