Disclosed herein is a method and system for providing a ringback tone (RBT). The system for providing an RBT to a user comprises: a sound file storage for storing a sound file; a user database receiving sound selection information from a user terminal, recording a sound identifier of the sound file corresponding to the sound selection information, receiving output position information of the selected sound file from the user terminal, and recording the sound position information; and an RBT providing unit reproducing a region which corresponds to the output position information from the sound file corresponding to the sound identifier with reference to the sound file storage and the user database so as to be provided as an RBT.

Method and system for providing ring back tone played at a point selected by user

An application interoperation method includes: maintaining a handler table including data type information, function information and calling information associated with each application installed in a portable device; receiving input information on a menu key of the portable device, from a user, while a first application is active; extracting, in response to the receipt of the input information, at least one function information associated with data type information, which is being processed or requested by the first application, from the handler table; dynamically generating a menu including the extracted function information to provide the user with the generated menu; receiving selection information on particular function information among the provided menu, from the user; and identifying calling information associated with the selected particular function information by referring to the handler table and executing a second application based on the identified calling information.

Since music signals are encoded by a voice encoding method optimized to human voice signals such as EVRC (Enhanced Variable Rate Coding) in a cellular communication system, the music signals are often distorted by such encoding method, and listeners experience pauses in music caused by such voice-optimized encoding method. To improve the perceptual sound quality of music, a method for preprocessing digital audio data is provided in order to prevent the problem of pause in music signals in a cellular phone. In particular, AGC (Automatic Gain Control) preprocessing and PHE (Pitch Harmonics Enhancement) is performed to the digital audio data having low dynamic range. By this method, the number of pauses in music signal is reduced, and the perceptual sound quality of the music is improved.
