Note information is exactly in meta-event, and all meta-event are started with 0xFF, and wherein note information is exactly 0x7F
Beginning, so by identifying that 0xFF and 0x7F can obtain each note of user recording audio, and looked into scoring systems
The score of each note is ask, establishes and sings score-note corresponding relationship, is then calculated by the multiple recorded audios of user every
The average of a note determines that the average mark of all notes, all notes are averaged further according to the average of each note
Point i.e. note mean parameter, and then show that (for example score is higher than all pitches and being averaged for user's score higher range scope
The part of score).
Wherein, the average mark of each note can be obtained according to multiple recorded audios of user, will be in multiple recorded audios
The score of identical note seeks weighted average, using the weighted average acquired as the average of the note.
Optionally, server determines that range scope can wrap according to the pitch parameters of pitch parameters average value and each note
It includes: according to sequence of the tone represented by note from bass to high pitch, first being higher than the first sound of pitch parameters average value
Accord with the lower limit as range scope；According to sequence of the tone represented by note from high pitch to bass, it is higher than tone for first
The upper limit of second note of mean parameter as range scope；Tone represented by the continuous note between the upper limit is limited to by under
As range scope.
As shown in figure 5, note includes C, #C, D, #D, E, F, #F, G, #G, A, #A, B, these notes in all records of user
