Embodiment 1

[0028] The embodiment of the present invention provides a music special effect matching method, which can be applied to the server of the music special effect matching device, seefigure 1 A flow chart of a music special effect matching method shown, the method includes the following steps:

[0029] Step S102, acquiring the audio data to be matched, and detecting the tempo of the audio data.

[0030] Usually, when the matched audio data is obtained, the audio data can be a specific music file, such as a pre-stored complete audio data, or a real-time audio data stream, such as real-time recorded audio data.

[0031] Step S104, judging whether the detected beat is a rhythm change point of the audio data;

[0032] Usually, the rhythm change point is the time point corresponding to the beat of the rhythm of the audio data. In actual implementation, the rhythm change point includes but is not limited to obvious changes in musical instrument sounds, obvious changes in human voice, ob...

Embodiment 2

[0106] On the basis of the above embodiments, the embodiment of the present invention also provides a music special effect matching device, such as Figure 4 A schematic structural diagram of a music special effect matching device shown, the device includes the following modules:

[0107] The audio acquisition module 400 is used to acquire the audio data to be matched, and detect the beat of the audio data;

[0108] A judging module 402, configured to judge whether the detected beat is a rhythm change point of the audio data;

[0109] Marking module 404, for when the judgment result of judging module is yes, beat is marked as optional music paragraph starting point, generates starting point list, and wherein, starting point list includes a plurality of optional music paragraph starting points;

[0110] Divide module 406, be used for selecting the starting point according to preset starting point selection rule, select music paragraph starting point in starting point list, audio...

Abstract

The invention provides a music special effect matching method and device, and relates to the technical field of music recognition. The method comprises the steps: acquiring to-be-matched audio data, and detecting the beat of the audio data; determining whether the beat is a rhythm change point of the audio data or not: mark the beat as a starting point of an optional music passage if the beat is the rhythm change point of the audio data, or else generating a starting point list; selecting the starting point of the music passage in the starting point list according to a preset starting point selection rule, and dividing the audio data into multiple music passages; setting an emotional label of each music passage, and calculating the emotional score of each emotional label; searching for a visual expression effect matched with the emotional score in a pre-stored special effect database and storing the visual expression effect in association with the music passage, so that the audio datais read and the visual expression effect is played. The method and device provided by the invention facilitate the emotion interaction between the user and music, and improves the user experience.

Description

technical field [0001] The invention relates to the technical field of music recognition, in particular to a music special effect matching method and device. Background technique [0002] At present, many portable devices can play music, and in the process of playing music, people begin to pursue personalized playback modes and emphasize the emotional interaction process with music. In the prior art, most of the recognition of music is to recognize the style or emotion of the whole song, and match the whole music with music special effects. The classification categories are generally few, and the matching is monotonous, which cannot meet the needs of users. Personalized requirements lead to problems such as poor user experience. [0003] Aiming at the above-mentioned problem of single music recognition and monotonous matching, resulting in poor user experience, no effective solution has been proposed yet. Contents of the invention [0004] In view of this, the object of ...
