<p>A score tracking method and apparatus are provided. The score tracking method includes a first step of detecting a list of frequency models, which are expected to occur during performance of a score, from score information; a second step of generating a matching model, which is composed of frequency components that are expected to be included in audio data externally input at the time point, based on the frequency model list; a third step of receiving external audio data, converting the audio data into digital signal, and detecting current performance frequency data from the digital signal; a fourth step of determining whether a new frequency component is included in the current performance frequency data; a fifth step of determining whether the matching model matches the current performance frequency data when a new frequency component is included in the current performance frequency data; and a sixth step of generating synchronized information between the current performing notes and the score notes updating the matching model matches the current performance frequency data in the fifth step. Through those steps, a performance location in the score is automatically determined, and the result of determination is provided to a user.</p> |
