摘要： The invention relates to a music synthesis system for synthesizing a corresponding digital music output according to commands from a music data file. The music data file comprises a plurality of music data units. Each music data unit records related information of the music. The music synthesis system comprises a wavetable, a memory, a music analyzer, a wavetable preprocessor, and a synthesizer. The wavetable pre-stores the digital sampling data. The memory has a predetermined memory capacity for storing data. The music analyzer receives the music data file, analyzes the music data units of the music data file, and generates a corresponding analysis result. The wavetable preprocessor selects the digital sampling data with relatively greater importance in the wavetable and stores the selected digital sampling data in the memory. The synthesizer selects the digital sampling data from the memory and synthesizes the digital music output.

摘要： A karaoke scoring apparatus includes a memory element, a feature extraction element, a similarity measurement element, and a scoring element. The karaoke system includes a reference audio input to be compared with a target audio input for giving a score. The reference audio input and the target audio input are sampled respectively and are transformed sequentially to plural frames of reference sampling signals and plural frames of target sampling signals. The memory element is used for storing the frame of reference sampling signal and the frame of target sampling signal. The feature extraction element is used for performing autocorrelation calculation on the frame of reference sampling signal and the frame of target sampling signal. The similarity measurement element is used for generating a similarity result. The scoring element is used for calculating the similarity results corresponding to the plural frames of sampling signals to output final score.
