| titleOfInvention | A kind of based on two points approach dynamic time consolidation coupling music singing search method |
| abstract | The invention discloses a kind of based on two points approach dynamic time consolidation coupling music singing search method, described technical field relates to audio retrieval and singing search technology, and the method includes two parts, and one is to build musical database by MIDI music file.Two is the feature extracting humming fragment, and carries out with music database schema approaching mating and returning retrieval result of dynamic time consolidation based on two points.Comprise the following steps: be first normalized humming fragment, bandpass filtering, preemphasis, windowing framing etc. process；Then carry out filtering quiet section, pitch Detection, median smoothing etc. process；Finally carry out based on two points of couplings approaching dynamic time consolidation, according to the descending sequence of matching rate and return result.It is an advantage of the invention that sequence of notes time point alignment problem and note relative pitch two hang-up solving music retrieval；Retrieval hit rate can be significantly improved. |
