I hear a bad humming noise in the background. What is it and how do I get rid of it?
Hum from 60-cycle household current is a common problem. It can arise from several different sources and you will probably need to experiment to determine the best way to address your hum problem. One of the most common causes of hum is the electrical connection of the computer chassis or sound card to the audio source. The best way to address this is to use a ground loop isolator, as described on my Dubbing Vinyl Albums to CD Page. This will electrically isolate the computer from the audio source. However, you may also find that the source of your hum has nothing to do with the connection of the computer to the audio source. It may be due to some more common problem. If you are dubbing an album from a turntable, make sure that the ground wire for the turntable is connected to the chassis of the receiver/amplifier/preamplifier. Route your audio signal cables away from transformers, power supplies, electrical extension cords, and fluorescent lights. In some cases, you may even find that
