Problems solved by technology
[0004] The audio recommendation method based on sound features requires a lot of calculations and the complexity of the algorithm is too high. Especially for new songs that have just been released, it is difficult to calculate the similarity with a large number of old songs in a timely manner, so the recommendation takes a long time and cannot be timely.

Embodiment Construction
[0028] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0029] Before explaining the embodiments of the present invention in detail, some proper nouns involved in the present invention will be explained first.
[0030] Main theme: refers to the pitch trend of the singer's singing part in an audio (that is, a song), that is, the melody theme.
[0031] Pitch: Refers to various high and low sounds, that is, the height of the sound, one of the basic characteristics of the sound. The pitch of the sound is determined by the vibration frequency, and the two are directly proportional: the higher the frequency (that is, the more vibrations per unit time), the higher the sound, and the lower the sound. Among them, the regularized calculation formula of pitch is 12*log 2 f / 440+69.5.

The invention discloses an audio frequency recommendation method and a device, and belongs to the technical field of multi-media processing. The method comprises the steps that a first musical composition information of a current deductive audio and a second musical composition information of at least one candidate audios are obtained; for each of the candidate audios, the distance information between the first musical composition information and the second musical composition information of the candidate audios is computed; based on the distance information, the theme similarity between the candidate audios and the current deductive audio is computed; and based on the theme similarity between each of the candidate audios and the current deductive audio, a pending-to-recommend audio is determined from the candidate audios. The theme similarity between the first musical composition information and the second musical composition information is computed based on the quantified distance between the two, video frequency recommendations are further achieved based on the theme similarity, because the computation amount of the recommendation method is little, the algorithm is low in complexity, the time consumed for recommendations is short, and video frequency recommendations can be timely conducted.
Description
technical field [0001] The present invention relates to the technical field of multimedia processing, in particular to an audio recommendation method and device. Background technique [0002] With the rapid development of technology, mobile terminals have more and more functions, which provide great convenience for people's daily leisure and entertainment. For example, karaoke applications can be installed on smart mobile terminals nowadays, and users can realize karaoke anytime, anywhere through karaoke applications without entering a KTV. During the singing process, in order to prevent users from repeatedly performing search operations to determine the interpretation audio, most karaoke applications provide an audio recommendation function, that is, perform audio recommendation based on the user's current interpretation audio. [0003] At present, when making audio recommendations, a combination of multiple dimensions is mainly adopted. For example, through the combinatio...
