Description
Technical Field
The invention relates to a song volume processing technology, in particular to a method for efficiently processing song volume balance.
Background
KTV need use a large amount of songs, have the caption, video and former vocal accompaniment sound, because the song file source is not unified, the sound of song does not have very big difference now, and the sound size between the former song of same song sings and the accompaniment also probably is different, and this kind of difference is passed through effect ware and power amplifier and is enlargied the back, and the volume change between two songs around leading to changes greatly, destroys very greatly to audio equipment, also seriously influences KTV guest's experience.
The volume of each song is manually processed, steps are complicated, time is wasted, only 3 songs can be processed by one person in a short time by calculating one song according to the speed of 20 minutes, the processing standard is not unified due to long time and influence of personal emotion and perception, and the unified standard cannot be guaranteed even by cooperation of multiple persons.
There is another common method, that is, the output volume of each song is marked in the database, the output volume of the song with large original volume is reduced, and the output volume of the song with small original volume is turned up. But the volume adjustment range is limited to 1-100, in the case of large volume, an effective standard volume value cannot be determined, the original volume of some songs is too small, and even if the output is adjusted to the maximum 100, the volume of some songs output 10 cannot be reached. Meanwhile, most of one song lasts for 3-5 minutes, the volume of different stages is high or low, and the difficulty is higher. Meanwhile, the songs of the KTV are continuously updated, and the song tunes in different periods are changed along with the fashion trend. Therefore, the standard volume value needs to adapt to the trend of the new song and the popular music, and the volume balance adjustment is continuously carried out.
Disclosure of Invention
In order to solve the technical problem, the invention discloses a method for efficiently processing song volume balance. The volume detection method is simple and visual, the detection speed is high, the equalization processing process realizes batch and automation, the volume detection method can be simultaneously deployed on a plurality of computers and cooperatively works, the speed is high, the equalization result is standardized, the volume of the original sound and the volume of the accompaniment of the same song are unified, the volume of the original sound or the volume of the left track and the right track of the accompaniment are unified, the artificial subjective factors are eliminated, and the quality of the song and the music is not influenced.
The technical scheme adopted by the invention is as follows.
A method for efficiently processing song volume equalization comprises the following steps:
step one, obtaining a song sample library, and obtaining the volume of each song in the song sample library;
step two, obtaining a volume balance standard value M or a range of the volume balance standard value M;
step three, carrying out volume equalization:
a. importing a song file;
b. decomposing the song file into a video file and an audio file;
c. separating the left and right sound channels of the audio file, respectively detecting to obtain a volume value N, and if a detection value is out of an effective range of a volume equalization standard value M, amplifying or reducing the audio data to the effective range of the volume equalization standard value M according to a proportion F to obtain an adjusted audio file;
e: and synthesizing the video file and the adjusted audio file to generate a new song file.
In the second step, the songs in the song sample library are divided into 100 intervals according to the song audio volume from small to large, and the average value range of the song audio volumes of the first 20 intervals with the largest number is taken as the range of the volume balance standard value M or the total average value of the song audio volumes of the first 20 intervals with the largest number is taken as the volume balance standard value M.
In a further improvement, the song sample library is a total song library, and the songs in the total song library are ranked from the top 20% of the songs in the high ranking according to the on-demand number.
Further improvement, the number of songs in the song sample library is n, and n is not less than 500 songs in the total song library from n before high ranking according to the on-demand number.
Further improvement, the song sample library is set with a statistical period K, and ordering ranking is carried out to update the songs.
In step c, the sound volumes of the left and right channels of the song are respectively processed and adjusted to be the same sound volume.
In a further improvement, in the step one, the volume of each song is obtained by the following method: extracting the audio data of each song in the song sample library, and then calculating to obtain the average value of the audio volume of each song as the volume of each song
The invention has the advantages that:
1. the volume detection method is simple and visual, and the detection speed is high.
2. The equalization processing process realizes batch and automation, can be deployed on a plurality of computers at the same time, and can work cooperatively, and the speed is high.
3. The equalization result is standardized, the sound volume of the original sound and the sound volume of the accompaniment of the same song are unified, the sound volume of the left track and the right track of the original sound or the accompaniment is unified, and artificial subjective factors are eliminated.
4. The music quality of the song is not affected.
Detailed Description
Example 1
The first stage is as follows: and establishing a volume rapid detection algorithm.
And after converting the audio file into the wav format, sampling and adding the audio data in the wav file, and averaging. The method is used for analyzing 10 ten thousand songs, 500 songs with the largest value, 500 songs with the smallest value and 500 songs selected randomly are respectively selected from 10 ten thousand data, 1500 songs are counted and played in the same environment, a volume detector and a plurality of persons are used for listening, and the average value can represent the volume of sound, wherein the larger the average value is, the larger the sound is, the smaller the average value is and the smaller the sound is.
And a second stage: and determining a volume balance standard value M.
The analysis data of 10 ten thousand songs are divided into 100 intervals from small to large, and the average value of the first 20 intervals with the largest number is taken as the sound volume balance standard value M.
And a third stage: automatic processing of song volume with reference to a standard
The first step is as follows: importing a song file;
the second step is that: decomposing the song file into a video file and an audio file;
the third step: and separating the left and right sound channels of the audio file, respectively detecting to obtain a volume value N, and if the detection value is out of the effective range of the equalization standard value, amplifying or reducing the audio data according to the proportion F.
The fourth step: and synthesizing the processed left and right channels into an audio file.
The fifth step: and when the song has a plurality of audio files, repeating the third step and the fourth step to process all the audio files.
And a sixth step: and synthesizing the video file and the audio file to generate a new song file.
