Abstract
A computerized method adjusts two presented audio signals using an audio player. A first audio signal is received and played through an audio playing unit. When a second audio signal that is inserted to be played is received in time during the playing of the first audio signal, a peak amplitude X of a volume of the first audio signal and a peak amplitude Y of a volume of the second audio signal are extracted. Each of the peak amplitude X and the peak amplitude Y are compared with a predetermined threshold value A. The first audio signal and/or the second audio signal are adjusted according to the comparison, and the first audio signal and/or the second audio signal is outputted to the audio playing unit and played through the audio playing unit according to the adjustment for the first audio signal and/or the second audio signal.
