PURPOSE: A tone level adjusting method is provided to adjust a tone level of a regenerated karaoke audio according to a feature of the karaoke audio and a user's singing capability as well as to prevent plural karaoke audios from being regenerated at the same tone level. CONSTITUTION: The method comprises several steps. A microcomputer performs a series of operations for continuously monitoring and checking key values inputted by a user while a karaoke system is being bootstrapped(S10,S11). In a case that the input key value is for adjusting a tone level(S12), the microcomputer stores the tone level adjustment value at a memory(S13). But in a case that the input key value is not for adjusting a tone level, the microcomputer performs a corresponding operation(S18). In a case that the user selects an audio among plural audios recorded on a disc and requests a regeneration of the selected audio(S14), the microcomputer searches for navigation information previously downloaded at a memory in order to check the tone level information corresponding to the selected audio(S15). The microcomputer compares the checked tone level information with the selected tone level value(S16). The microcomputer adjusts a tone level of the selected audio according to the comparison result, and regenerates the karaoke audio at the adjusted tone level(S17).
