Problems solved by technology

[0005] In order to solve the problem that in the existing karaoke rhythm prompting technology, the subtitles that change color with the music rhythm need to be recorded in advance, and different songs need to be re-recorded, which not only increases the cost of karaoke, but also does not use large-scale promotion and application. The present invention The embodiment provides a song accompaniment audio data processing method and device

Embodiment 1

[0096] The embodiment of the present invention provides a kind of song accompaniment audio data processing method, see figure 1 , the method includes:

[0097] Step S11, reading the song accompaniment audio data.

[0098] Step S12, determining the rhythm point of the song accompaniment audio data in real time.

[0099] Step S13, outputting an accompaniment prompt sound at the time corresponding to the determined rhythm point.

[0100] Specifically, at the moment corresponding to the rhythm point, a specific rhythm prompt sound can be output, the prompt sound includes but not limited to sounds such as drums, pianos, whistles, and castanets. In addition, you can also choose to directly output the prompt sound The volume of the accompaniment is increased to highlight the accompaniment of this part, so as to achieve the effect of prompting.

[0101] Further, the generated rhythm prompt tone can be played alone, or mixed with the accompaniment to form a new accompaniment and the...

Embodiment 2

[0105] The embodiment of the present invention provides a kind of song accompaniment audio data processing method, see figure 2 , the method includes:

[0106] Step S21, reading the song accompaniment audio data.

[0107] Step S22, performing frame division processing on the song accompaniment audio data to obtain multi-frame sampling data.

[0108] Specifically, for a song with a sampling rate of 48 kHz, a frame length of 960 samples (20 ms) and a frame shift of 480 samples may be used. It is easy to know that the sampling data is a time-domain signal.

[0109] The above sampling parameters are just examples and can be reselected according to the actual situation. For example, for a song with a sampling rate of 44.1kHz, a frame length of 1024 samples (23.2ms) and a frame shift of 512 points can be used.

[0110] Step S23, calculating the spectral flux of each frame of sampled data, and obtaining a spectral flux characteristic curve, and the peak point on the spectral flux...

Embodiment 3

[0183] The embodiment of the present invention provides a song accompaniment audio data processing device, see Figure 4 , the device includes: a reading module 301 , a determining module 302 and an output module 303 .

[0184] The reading module 301 is used for reading song accompaniment audio data.

[0185] The determination module 302 is used for determining the rhythm point of the song accompaniment audio data in real time.

[0186] The output module 303 is configured to output an accompaniment prompt sound at a time corresponding to the determined rhythm point.

[0187] Specifically, at the moment corresponding to the rhythm point, the output module 303 can output a specific rhythm prompt sound, the prompt sound includes but not limited to sounds such as drums, pianos, whistles, and castanets. In addition, you can also choose to directly output the The volume of the accompaniment at the moment of the prompt tone is increased to highlight the part of the accompaniment, w...

Abstract

The invention discloses a song accompaniment audio data processing method and device and belongs to the technical field of audio processing. The method comprises reading song accompaniment audio data; determining the rhythmical points of the song accompaniment audio data in real time; outputting accompaniment prompt tones at the corresponding moments of the determined rhythmical points. By reading the song accompaniment audio data and outputting the accompaniment prompt tones at the corresponding moments of the extracted rhythmical points, the song accompaniment audio data processing method and device enhances the rhythm feeling of songs, enables a consumer to keep race with rhythm, enhances the consumption experience of karaoke, saves recording of the song and facilitates mass application.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to a song accompaniment audio data processing method and device. Background technique [0002] Along with improving constantly of people's consumption level, karaoke is also more and more subject to liking of people. But for some consumers who have a bad sense of rhythm, in the process of singing karaoke, it is easy to start singing ahead of the rhythm of the song or not keep up with the rhythm of the song, which often reduces people's consumption interest in karaoke. [0003] In the existing karaoke technology, by changing the subtitles of the song along with the rhythm of the music, its color is changed to prompt the singer so that it can keep singing in sync with the rhythm of the song without going out of tune. [0004] Subtitles that change color with the rhythm of the music need to be recorded in advance, and different songs need to be re-recorded with subtitles, whi...
