摘要: The problem of automatic melody line identification in a MIDI file plays an important role towards taking QBH systems to the next level. We present here, novel algorithm identify polyphonic file. A note pruning and track / channel ranking method is used line. use results from musicology derive certain simple heuristics for stage. This helps robustness algorithm, by way discarding “spurious” notes. based on melodic information each enables us choose accurately. Our makes no assumption about performer specific parameters, achieves accuracy 97% identifying correctly. currently being system built our lab.
