I am simply trying to create a voice clip with Sound Recorder and a
mike from Wal-Mart. The humming is so bad it is as loud as the voice!
I bought another mike. Same deal. I have played with the sound
settings, to no avail. I tried MS Movie Maker. Same problem. I tried
to mess with the audio properties, but they stay grayed out, whether I
have selected a clip or not. Haaalp!



What computer/sound card?
Whatever program you use the sound comes through the same system. The
mic input on non-specialist systems is often of really lousy quality.

If this is a laptop machine, try recording on battery power - unplug
the mains adaptor.

Cheap microphones won't sound very good, but the problem isn't usually
serious hum.
