Sorry you have a problem. Is it the 60 cycle hum of U.S. electircal systems or the whirl of the fan?

What type of laptop? Where is the power-supply?

Look up the Graphic EQ

Can you isolate it to a single track?

What and where are your input devices (microphone type)

This is from the software tutorial:

Having trouble recording digital audio? Here are some things to check:

·        Check that the microphone is plugged into the microphone jack on the back of your computer. It should be labeled "MIC IN" or "MICROPHONE".
·        Check the levels on the Windows 95 software volume control:

1.        If you see a small speaker icon in the lower left of the Windows 95 taskbar, double-click on it. Otherwise, open the Windows 95 start menu, and start the Volume Control program, located in the folder Programs / Accessories / Multimedia.
2.        Make sure you see a control called Microphone Balance. If not, choose Options | Properties, select the option to show the Microphone volume control, then click OK.
3.        Turn the microphone volume up with the slider, and make sure the Mute option is not selected.

·        Make sure that the Source setting for the track you are recording is set to your digital audio device. To change the Source setting:

1.        In the Track view, double-click in the track's Source column.
2.        In the Track Properties dialog box, change the Source setting to the Left channel of your digital audio device. (Right will probably work also.)
3.        Click OK.

If you're not sure which Source option to use, you can keep trying until one works.

Sincerely,
