Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0041] This embodiment provides a method for extracting a singer's effective range, such as figure 1 Shown include the following steps:

[0042] Step S1: recording a cappella recording file when the user sings a song;

[0043] Step S2: Using the MELODIA algorithm to analyze the user's a cappella recording file, extract the pitch sequence when the user sings, convert it into a MIDI pitch value sequence, and regularize it into a MIDI pitch value sequence corresponding to the basic pitch level;

[0044]Step S3: Collect and organize the numbered notation of the songs sung by users in the music library, convert the numbered notation information into the corresponding MIDI pitch value sequence according to the key signature and roll name in the numbered notation of the song, and according to the start time and duration of the corresponding song accompaniment...

Abstract

The invention relates to a singer effective range extraction method. The method comprises steps that an MIDI pitch value sequence of a singer singing a song can be acquired through analyzing a recording file of the song sung by the singer; an MIDI pitch reference sequence of the same song is acquired through analyzing the notation information of the same song in a music database; the completion quality of a sound level X is defined as the proportion of accurate singing times of the sound level X of the singer to the total occurrence times of the sound level X in the notation; on the condition that a sound level completion degree is greater than a designated threshold, the smallest basic sound level of MIDI values and the largest basic sound level of the MIDI values of the singer are extracted and are taken as an effective range of the singer; when the singer sings a new song, and the effect range scope is expanded, the effective range of the singer is updated. Through analysis on the effective range of the singer, songs suitable for being sung in the effective range in the music database can be recommended to the singer.

Description

technical field [0001] The invention relates to an audio signal processing method in the field of singing, in particular to a method for extracting a singer's effective range. Background technique [0002] In order to better introduce the concept of range, some basic concepts of music theory are introduced first. [0003] Tone system: The sum of tones with a fixed pitch used in music is called the tone system. [0004] Tone column: The tones in the musical tone system are arranged in ascending or descending order, called the tone column. [0005] Tone level: Each tone in the musical tone system is called a tone level. There are two kinds of sound levels: basic sound level and changing sound level. The basic sound levels include C, D, E, F, G, A, B, namely do, re, mi, fa, sol, la, si. The sound obtained by raising or lowering the basic sound level is called the change sound level. Such as # C, # D, # E, # F, # G, # A, # b. [0006] Range: There are two types of r...
