In addition, the present invention provides a method for producing a ringtone for notifying the incoming call, comprising: a first step of analyzing a range of voice melody input from a user computer and converting it into a MIDI signal; A second step of analyzing chordal characteristics of the corresponding melody converted into the MIDI signal in the step and setting a chord most suitable for the melody; And a third step of generating a ringtone by performing an arrangement operation of transposing (transposing) the corresponding chord to the tone by applying the selected musical instrument to the chord set in the above step.

As described above, according to the present invention, by analyzing and arranging a voice melody input by a user, an original and unique ringtone can be produced by producing a ringtone informing of a call reception of a mobile communication terminal.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view schematically showing a ringtone production system according to the present invention. As shown in the figure, a user computer 11 for transmitting a voice melody that the user thought of together with a request for the production of a ringtone for the production of a unique ringtone of the user and a mobile communication terminal 12 for which the produced ringtone is to be downloaded. Are connected to the ringtone production server 30 via the wired / wireless communication network 20, respectively.

The ringtone production server 30, as shown in Figure 2, has a data transmission and reception unit 31 for communicating with the user computer 11 and the mobile communication terminal 12 via a wired or wireless communication network 20 In addition, the control unit 32 for generating a ringtone to be used in the mobile communication terminal 12 by analyzing and arranging the voice melody transmitted from the user computer 11 through the data transmission and reception unit 31.

To this end, the control unit 32 includes a melody analysis unit 33, a code analysis unit 34, and an arranging unit 35. The melody analyzer 33 analyzes the range of the voice melody transmitted from the user computer 11 and converts the melody into a musical instrument digital interface (MIDI) signal, and filters the converted MIDI signal to correct the beat and pitch of the melody. do.

The chord analyzing unit 34 analyzes the harmonic characteristics of the corresponding melody in order to add musical notes to the user's melody converted by the melody analyzing unit 33 into the MIDI signal, that is, the chord, that is, the chord Performs the function for setting (chord).

The arranger 35 transposes (transposes) the corresponding chords by applying various musical instruments such as chord musical instrument sounds, rhythm musical instrument sounds, and effect sounds to the codes set by the chord analyzer 34 according to a user's selection. It performs the function.

On the other hand, the ringtone production server 30 stores a user ID and password for member authentication, and also includes a member information database 36 for storing the ringtone produced for download to the mobile communication terminal 12, and also the melody An instrument sound source database 37 for storing sound source data of various instruments to be used for arranging is provided.

Next, an operation method of the ringtone production system according to the present invention configured as described above will be described with reference to FIG. 3.

3 is a flowchart illustrating a ringtone production method according to the present invention. When the user computer 11 is connected to the ringtone production server 30 through a wired / wireless communication network 20, the ringtone production server 30 is connected to the user computer 11. The user ID and password transmitted from the user information is inquired into the member information database 36 to perform member authentication (ST101).

When a voice melody conceived by the user is input together with a request for production of a ringtone from the user's authenticated user computer 11 (ST102 to ST103), the melody analyzer 33 analyzes the range of the input voice melody as a MIDI signal. It converts (ST104). In addition, the melody analyzer 33 filters the converted MIDI signal to correct the beat and pitch of the melody. In other words, since the MIDI melody coded voice melody is inconsistent in time and pitch, quantization and pitch banding are performed to correct the time and pitch.

As described above, the melody converted into the MIDI signal by the melody analyzer 33 is 1 poly, that is, a single tone, a dry melody. In order to develop this into a form of music, it is necessary to add musical notes such as piano left hand accompaniment, bass guitar, synthesizer, etc. to the melody converted into MIDI signals.

To this end, the chord analysis unit 34 of the ringtone production server 30 analyzes the chord characteristics of the corresponding melody converted into a MIDI signal and sets the most suitable chord, that is, chord, chord for the melody (ST105). If this is explained in more detail as follows.

The melody entered by the user is fast (tempo). Tempo such as moderato (medium fast) and andante (slow) may be defined in terms of bpm, for example, moderato, such as 100 bpm (beats-per-minute tempo).

Assuming that the melody entered by the user is 4 bars, the tempo of the melody is moderato (100 bpm), and it takes 20 seconds to play this melody from start to finish, the time it takes to play 1 bar is 5 seconds. Analyzes the recorded notes and sets the most appropriate chord to that section's chord. For example, if a note called "sol solar" is uttered in one bar, the C chord is set to that bar.

When a chord corresponding to each measure is generated through the above process, a chord is generated by transposing (transposing) the chord to a tone by applying a musical instrument selected according to a user's preference to the chord and generating a ringtone. (ST106-ST107).

In the present embodiment, the sound source data of various instruments to be used for melody arrangement is stored in the instrument sound source database 37 and the sound sources of various instruments are cut through a cut and paste operation by dragging a mouse for the convenience of the user. It can be applied to the set code. In other words, the chord of the set melody is displayed on one side of the screen, and various instruments are displayed on the right side, and when the user drags the required instrument with a mouse and pastes it on the melody chord, the instrument sounds according to the chord. ) Is done.

If the user is not satisfied with the ringtone generated through the arrangement process as described above, the ringtone production server 30 repeats the above-described arrangement process for arranging work using another instrument, and the user is satisfied with the ringtone generated through the arrangement process. Then, the ringtone production server 30 stores the ringtone data generated in the corresponding user area of the member information database 36 so that the user can download it through the mobile communication terminal 12 (ST108 to ST109).
