Abstract

The invention discloses a note correction method and a note correction device, and belongs to the technical field of computer. The method comprises the following scale steps: acquiring each note included in note data of a target song, and determining the scale step frequency range which appears most frequently in the scale step frequency ranges to which the notes belong respectively; setting multiple scale step frequency ranges corresponding to the basic scale steps based on scale step sorting, wherein the multiple scale step frequency ranges include the scale step frequency range which appears most frequently; and for the notes of which the scale step frequency ranges do not correspond to the basic scale steps in the note data, adjusting the frequency values of the notes to the scale step frequency ranges corresponding to the basic scale steps to get corrected note data. By using the method and the device, note correction can be realized in the absence of standard note data.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for correcting musical notes. Background technique [0002] After the user records the audio of the song through the singing application, the singing application will extract the note data based on the recorded original human voice audio data. The extraction process is: first group the frequency points in the original human voice audio data, Divide multiple continuous frequency points with close frequencies into a note, and then calculate the corresponding frequency of the note based on the frequency of each frequency point contained in each note, and determine each frequency point based on the time of each frequency point contained in each note. The start time point and duration of the note, and then determine the identification of the frequency interval of the sound level to which the frequency of each note belongs, and then the note data corresponding to ...
