Problems solved by technology

However, limited by the volume adjustment range between 1 and 100, it is impossible to determine an effective standard volume value in the case of a large volume. Some songs output a volume of 10
At the same time, a song usually lasts 3 to 5 minutes, and the volume itself will be different at different stages, which makes it more difficult

Embodiment 1

[0027] The first stage: establish a volume fast detection algorithm.

[0028] After converting the audio file into wav format, add the audio data samples in the wav file and take the average value. Use this method to analyze 100,000 songs. From the 100,000 data, respectively take 500 songs with the largest value, 500 songs with the smallest value, and 500 songs randomly selected, a total of 1,500 songs. Under the same environment Play, use the volume detector and multiple people to audition, prove that the average value can represent the volume of the sound, the larger the average value, the louder the sound, and the smaller the average value, the smaller the sound.

[0029] The second stage: determine the volume equalization standard value M.

[0030] The analysis data of 100,000 songs is divided into 100 intervals from small to large, and the average value of the top 20 intervals with the largest number is taken as the volume balance standard value M.

[0031] The third st...

Abstract

The invention discloses a method for efficiently processing song volume equalization, which comprises the following steps of: 1, obtaining a song sample library, extracting audio data of each song inthe song sample library, and then calculating to obtain an average value of the audio volume of each song; measuring the volume of each song according to the average value of the song audio volume; step 2, obtaining a volume equalization standard value M or a range of M; and step 3, carrying out volume equalization. The volume detection method is simple and visual; the detection speed is high, batch and automation of the equalization processing process are realized, simultaneous deployment and cooperative work can be performed on multiple computers, the speed is high, the equalization result is standardized, the original sound and accompaniment volumes of the same song are unified, the left and right audio track volumes of the original sound or accompaniment are unified, artificial subjective factors are eliminated, and the song music quality is not influenced.

Description

technical field [0001] The invention relates to a song volume processing technology, in particular to a method for efficiently processing song volume equalization. Background technique [0002] KTV needs to use a large number of songs, with subtitles, videos and original accompaniment voices. Due to the inconsistency of the source of the song files, the voices of the existing songs are very different. , After this difference is amplified by the effector and the power amplifier, the volume between the two songs before and after will change greatly, which will greatly damage the audio equipment and seriously affect the experience of KTV guests. [0003] Manually process the volume of each song, the steps are cumbersome and time-consuming. If one song is calculated at a speed of 20 minutes, one person can only process 3 songs in one hour. Due to the long time, it is affected by personal emotions and perceptions , the same processing standard cannot be unified, and multi-person...
