Method of processing sound track
A method of processing a sound track includes providing a low frequency threshold and a high frequency threshold of an audible frequency range; selecting a low-pitch sound band from a lowest frequency of an original sound track to the low frequency threshold and raising the low-pitch sound band by a predetermined frequency shift to a modified low-pitch sound band, or selecting a high-pitch sound band from the high frequency threshold to the highest frequency of the original sound track and lowering the high-pitch sound band by a predetermined frequency shift to a modified high-pitch sound band; and combining original sound track and modified low-pitch sound band or combining original sound track and modified high-pitch sound band. The low and high frequency thresholds are not correlated. The predetermined frequency shift is one octave or multiple octaves or equals 2n, where n is a positive integer or a negative integer.
