A method and apparatus for outputting an audio signal and a method of adjusting the volume of an audio signal are provided. An embodiment of the present invention provides a method for outputting an audio signal that includes: (a) determining an output level of a modulated signal to be outputted for each respective frequency band by using a hearing threshold measured for the respective frequency band; and (b) outputting the modulated signal and an audio signal simultaneously. An embodiment of the present invention can improve hearing ability by outputting an audio signal and a modulated signal together. Also, according to an embodiment of the present invention, a user can use visual signals to personally set the output level of audio signals that is optimal for each frequency band in accordance with changes in the user's dynamic hearing threshold for each respective frequency band, even while listening to audio signals of which the output level for each frequency band was determined previously.

Method and apparatus for outputting audio signal, method for controlling volume

Disclosed is a method for generating audio data automatically and a personal terminal and a recorded medium using the same. Disclosed method comprises the steps of: (a) detecting pitch of inputted sound source; (b) generating a unit tone data using detected pith variation information; (c) generating an interval code using ratio information of unit tones included in the unit tone data; (d) generating a harmony code based on the generated interval code; (e) generating an accompaniment template using the harmony code and pre-stored accompaniment related template; and (f) generating an audio data where main melody of the inputted sound source and the accompaniment data are merged. Users can generate polyphonic ringtone sound automatically through a personal terminal itself without downloading.
