Problems solved by technology

[0003] At present, when various types of audio files are played through audio equipment, they are usually played at a fixed volume. The whole song or music is played at the same volume during playback. Although this operation is simple, it cannot better reflect the ups and downs of the song or music during playback.

Embodiment 1

[0034] In this embodiment, the audio data to be played is an audio file in .WAV format. In fact, there are many audio file formats, and audio files in any format are acceptable.

[0035] When using the method of dynamically adjusting the playback volume according to the wavelength of the present invention to play the audio data, such as figure 2 shown, including the following steps:

[0036] (1) read in the audio data to be played, and obtain the maximum wavelength and the minimum wavelength of the audio data, thereby obtaining the wavelength range of the audio data;

[0037] In this embodiment, one-time reading needs to play audio data, and the maximum wavelength of the audio data obtained by the method of automatic detection is 500 mm and the minimum wavelength is 10 mm, so that the wavelength range of the audio data obtained is 10-500 mm;

[0038] (2) The volume interval that the audio data needs to be played is set, and the maximum volume and the minimum volume of the au...

Embodiment 2

[0051] With the rapid development of computer network technology and the wide application of streaming media technology, more and more people like to enjoy music or songs online through the computer network; at this time, when users play audio files in various formats online, the audio data is usually not read at one time , but read in stages, each time only a part of the audio data is read, so when the method of the present invention is used to play, if the method of automatic wavelength detection is adopted, only part of the audio data read can be detected Obviously, the maximum wavelength and the minimum wavelength of the part of the audio data are not completely corresponding to the maximum wavelength and the minimum wavelength of the entire audio data. In order to solve this situation, the method of the present invention supports manual setting of the wavelength range.

[0052] The difference between this embodiment 2 and embodiment 1 lies in step (1) and step (4). In this...

Embodiment 3

[0054] In this embodiment, take playing a section of audio data in .AVI format as an example, when the system for dynamically adjusting the playback volume according to the wavelength of the present invention is used to play the audio data, as figure 1 As shown, the system includes: a file analysis module 11, a parameter setting module 12, a wavelength detection module 13, a volume calculation module 14, a volume adjustment module 15, an audio playback module 17, and an audio device 15, wherein the audio device 15 is respectively connected to the volume adjustment module. Module 16, audio playback module 17 are connected;

[0055] When the above-mentioned system was working, at first the format of the audio data was analyzed by the file analysis module 11, and the maximum wavelength of the audio data obtained by automatic detection was 500mm and the minimum wavelength was 10mm, so that the wavelength interval of the audio data obtained was 10- 500mm and pass the information to...

Abstract

The invention belongs to the field of audio data processing, and in particular relates to a method and system for dynamically adjusting playback volume according to wavelength. At present, when people play various audio files through audio devices, they all play them at a fixed volume, which cannot better reflect the ups and downs of the auditory effect of songs or music during playback. The system and method of the present invention correspond the wavelength of the audio data to the size of the volume, and dynamically detect the wavelength, calculate the volume value according to the wavelength, and then adjust the playback volume of the audio device to realize playing the same audio data with different volumes , that is, play at a high volume when the sound is heavy, and play at a low volume when it is soft, so that the heavy and light sounds of the audio data are played dynamically with the high and low frequencies of the audio equipment, achieving the effect of high and low sound fluctuations, increasing the user's entertainment experience and auditory experience.

Description

technical field [0001] The invention belongs to the field of audio data processing, and in particular relates to a method and system for dynamically adjusting playback volume according to wavelength. Background technique [0002] The rapid development of society has improved people's living standards day by day, and therefore made people's demand for music more and more. Especially with the continuous progress and application of computer network technology, audio files in many formats have appeared. It is very common to use computers to play audio files in various formats, and people have more opportunities to contact and appreciate music from various file formats. [0003] At present, when various types of audio files are played through audio equipment, they are usually played at a fixed volume. The entire song or music is played at the same volume during playback. Although such an operation is simple, it cannot better reflect the ups and downs of the auditory effect of th...
