Abstract
A method and apparatus for automatically compensating a tone color. The method includes a first step for determining whether a channel is modified or an input audio signal is switched, a second step for calculating frequency characteristics of the input audio signal and comparing the compared result with data in a basic table, a third step for determining the input audio signal as a least error mode during the second step, and a fourth step for compensating a tone color in accordance with the determined mode. The method and apparatus automatically adjusts a tone color by determining a present tone color in itself on the ground of the frequency energy being presently applied when a channel is modified, an input audio signal is switched, or a color sound mode is modified, thereby eliminating a manual manipulation by a user as well as providing an optimal sound.
