Abstract

The invention discloses an audio processing method and device, electronic equipment and a storage medium and relates to the technical field of computers. The audio processing method comprises the following steps of acquiring a time domain audio signal corresponding to to-be-detected electronic musical instrument equipment; performing frequency domain conversion processing on the time domain audiosignal to obtain a frequency domain audio signal; inputting the frequency domain audio signal into a pre-trained machine learning model; obtaining a fundamental frequency label corresponding to a frequency domain audio signal output by a pre-trained machine learning model; determining a target musical scale and a target score according to the fundamental frequency label and the corresponding relationship between the fundamental frequency label and the musical scale and the score; and based on the determined target musical scale and target score and the standard musical scale and standard scorecorresponding to the electronic musical instrument equipment to be detected. The time domain audio signal can be uploaded to any node server in the blockchain server system by the client. According to the method, intonation detection accuracy of the electronic musical instrument equipment is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to an audio processing method, device, electronic equipment and storage medium. Background technique [0002] Electronic musical instruments are widely loved as musical instruments that generate sounds through electronic signals. During the production process of electronic musical instruments, the sound signals generated by them need to be analyzed to detect the pitch of the sound signals generated by the electronic musical instruments. Only electronic musical instruments that pass the test can be put on the market for sale. [0003] In related technologies, when detecting electronic musical instruments, the sound signal generated by the electronic musical instrument is mainly compared with the standard sound signal for similarity, and only the electronic musical instrument whose similarity reaches a predetermined condition will be identified as qualified. The method o...
