Embodiment Construction

[0029] see image 3 , image 3 is a schematic diagram of the wavetable music synthesis system 40 of the present invention. The wavetable music synthesis system 40 of the present invention comprises a music file library 51, an analysis module 52, a judgment module 54, a musical instrument database 56, a memory 60, a synthesis module 66, a digital-to-analog conversion amplification device 68 and a loudspeaker 70. First set forth the data stored in the various databases of the present invention. There are many melodies stored in the music archive storehouse 51, and a predetermined number (M1+P1) of musical instrument data are stored in the musical instrument database 56, including M1 kinds of melody musical instrument data. And P1 percussion instrument data. For example, the musical instrument database may include 128 types of melody instrument data and 47 types of percussion instrument data. In this embodiment, the musical instrument database 56 is a high-capacity, low-cost,...

Abstract

It is a music synthesis system. This system consists of musical instrument database, which used for storing the first predefined types of musical instrument data; the storage with the predefined capacity, which used for storing the musical instrument data that required by synthesizing the music record; the analysis module, which used for analyzing the input music record, and get the second predefined types of musical instrument data in this music record; judgment module, which used for judging whether the total data volume of the second predefined types of musical instrument data larger than the predefined capacity of the storage; the synthesis module, which used for synthesizing the digital music signal according to the musical instrument data in the storage. If the judgment result of the judgment module is no, it takes out the second predefined types of musical instrument data from the music database and stores them to storage; if the result is yes, it executes the musical instrument replacement program, and changes the second predefined types of musical instrument data to the third predefined types of musical instrument data, whose total data volume will not over the predefined capacity of storage.

Description

technical field [0001] The invention relates to a music synthesis system, in particular to a music synthesis system applied in a communication device. Background technique [0002] see figure 1 , figure 1 It is a schematic diagram of a known wavetable music synthesis system 10 . The known wavetable synthesis system 10 includes a music archive 11 , an analysis module 12 , a music generator 14 , a digital-to-analog conversion amplification device 20 and a speaker 22 . When the known wave table music synthesis system 10 synthesizes a music file 13, the music file 13 is sent to the analysis module 12 by the music file storehouse 11, and the music file 13 will be performed by the analysis module 12 for note data and control commands (comprising the selection of musical instruments, volume and special effect setting... etc.), and then obtain the analysis data of the relevant music files 13 . [0003] The music generator 14 further comprises an instrument database 16 and a synt...
