Key information generation method and device, electronic equipment and computer readable medium

Abstract

The embodiment of the invention discloses a key information generation method and device, electronic equipment and a computer readable medium. A specific embodiment of the method comprises the following steps: determining a tone offset according to test audio information and a standard frequency corresponding to a target key; obtaining target audio information; performing audio clip extraction on the target audio information to generate audio clip information and obtain an audio clip information set; generating audio feature information based on the audio clip information set and the tone component offset, and obtaining an audio feature information set; and sequentially inputting the audio feature information in the audio feature information set into a pre-trained key recognition model to generate key information and obtain a key information set. According to the implementation mode, the accurate key information is generated by identifying the audio information under the condition that the piano sound is not accurate, so that the key information generation accuracy is improved.

Description

technical field [0001] The embodiments of the present disclosure relate to the field of computer technology, and in particular, to a method, an apparatus, an electronic device, and a computer-readable medium for generating key information. Background technique [0002] The key information generation is a technique for generating key information corresponding to the audio played by the user. At present, when the key information is generated, the method usually adopted is to directly analyze the audio played by the user to determine the key played by the user. [0003] However, when using the above method to generate key information, there are often the following technical problems: [0004] First, in the case of inaccurate piano sound, it is impossible to determine the real audio corresponding to the keys played by the user, which in turn leads to obtaining wrong key information, so that the accuracy of the generated key information is low; [0005] Second, since there is o...

AI Technical Summary

Problems solved by technology

[0004] First, in the case of inaccurate piano sounds, it is impossible to determine the real audio corresponding to the keys played by the user, which in turn leads to wrong key information, resulting in low accuracy of the generated key information;

[0005] Second, because there is often noise in the acquired audio played by the user, it will lead to inaccurate audio feature recognition, making the accuracy of the generated key information low;

[0006] Third, since the audio played by the user is often recorded indoors, reverberation is likely to exist in the audio, which makes the accuracy of the generated key information low
