Function Documentation

void matching

(

)

This function is the kernel of this program. We can divide it into four parts: (1) first, it handles the musician input in real time; (2) compares it with the score using the LCS problem algorithm; (3) updates the virtual clock according to the musician's tempo; (4) plays the accompaniment given the evolution of the virtual clock.
