The present invention relates to an audio synthesis system for performing
wavetable audio synthesis. The system comprises an instrument database,
an analysis module, a memory, a judgment module, and a synthesis module.
The instrument database is used for storing data of a first predetermined
number of musical instruments. The analysis module is used for analyzing
an inputted wavetable music to generate required data of a second
predetermined number of musical instruments. The memory has a
predetermined capacity for storing the required data of musical
instruments to synthesize the wavetable music. The judgment module is
used for judging whether the total amount of data of the second
predetermined number of musical instruments exceeds the predetermined
capacity. The synthesis module is used for synthesizing a digital music
signal according to the instrument data stored in the memory.
