Part of the Multimedia and graphics glossary:

Antialiasing is the smoothing of the image or sound roughness caused by aliasing . With images, approaches include adjusting pixel positions or setting pixel intensities so that there is a more gradual transition between the color of a line and the background color. With sound, aliases are removed by eliminating frequencies above half the sampling frequencies.
