Abstract:
1. A score tracking method comprising: detecting frequency models with pitch and length information of score notes to be performed, and compiling a list of frequency models; generating a matching model, which is composed of frequency components that are included in audio data to be generated during a performance of the score notes, based on the frequency model list; receiving external audio data during an actual performance of the score notes, converting the audio data into digital signal, and detecting current performance frequency data from the digital signal; determining whether the current performance frequency data includes a new frequency component; determining whether the matching model matches the current performance frequency data when the new frequency component is included in the current performance frequency data; and generating synchronized information between the actual performance of the score notes and the score notes and updating the matching model, when it is determined that the matching model matches the current performance frequency data; wherein detecting frequency models with pitch and length information of score notes to be performed, and compiling a list of frequency models comprises:
