Problems solved by technology

For example, if a song’s music score is in the key of C, but due to reasons such as voice-changing singing and the difficulty of controlling the voice changer of young people, the music in the key of E is sung, and the score will be very low or even zero if the frequency pitch is used for scoring.

Abstract

The invention discloses a music score tone modification adaptive method and system, and relates to the technical field of audio data processing. The method specifically comprises the following steps: recognizing a music score, reading the rhythm and pitch of the music score, and serializing the music score into a first array, wherein the pitch corresponds to a fixed numerical value, and the rhythm corresponds to a fixed time value, processing and serializing the audio file of a user into a second array; and comparing the first array and the second array, and determining the music score of the user through comparison of pitches in hours. By using the method of the invention, during singing scoring, various debugging singing of the same piece of music is adaptively adjusted, and objectivity and accuracy of music scoring are enhanced.

Description

technical field [0001] The present invention relates to the technical field of audio data processing, and more specifically relates to an adaptive method and system for music scoring and pitch shifting. Background technique [0002] Music scoring is a technology that provides real-time feedback on the user's personal singing. It can evaluate the singer's singing accuracy, bring a novel experience to the user, and improve the singing level. In the prior art, scoring is performed directly by the frequency and pitch of singing or playing. When the singer sings or plays the same piece of music with a different tone, this scoring method will make a wrong evaluation of most of the overall music. For example, if a song’s music score is in the key of C, but due to reasons such as voice-changing singing and the difficulty of controlling the voice changer of young people, the music in the key of E is sung, and the score will be very low or even zero if the frequency pitch is used for ...
