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 the .WAV format. In fact, there are multiple 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 audio data, such as figure 2 As shown, including the following steps:

[0036] (1) Read in the audio data that needs to be played, and obtain the maximum and minimum wavelengths of the audio data, so as to obtain the wavelength range of the audio data;

[0037] In this embodiment, the audio data that needs to be played is read in at a time, and the maximum wavelength of the audio data is 500 mm and the minimum wavelength is 10 mm through the automatic detection method, so that the wavelength range of the audio data is 10-500 mm;

[0038] (2) Set the volume interval that the audio data needs to be played, and determine the maximum volume and minimum volume of the a...

Embodiment 2

[0051] With the rapid development of computer network technology and the widespread application of streaming media technology, more people like to enjoy music or songs online through computer networks; at this time, when users play audio files in various formats online, the audio data is usually not read all at once. , It is read in stages, and only a part of the audio data is read each time. Therefore, when the method of the present invention is used for playback, if the automatic wavelength detection method is used, only part of the read audio data can be detected Obviously, the maximum and minimum wavelengths of this part of the audio data usually do not completely correspond to the maximum and minimum wavelengths 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 steps (1) and (4). In this embodiment, the user ...

Embodiment 3

[0054] In this embodiment, playing a piece of audio data in the .AVI format as an example, when the audio data is played using the system for dynamically adjusting the playback volume according to the wavelength of the present invention, such 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. Module 16, audio playback module 17 are connected;

[0055] When the above system works, the file analysis module 11 first analyzes the format of the audio data, and automatically detects that the maximum wavelength of the audio data is 500mm and the minimum wavelength is 10mm, so that the wavelength range of the audio data is 10- 500mm and pass the information to the parameter setting module; of course, in the actual operation process, the file analysis module also supports manual setting of th...

Abstract

The invention belongs to the audio data processing field, which in particular relates to a method and a system for dynamic regulation of the playing volume according to wavelength. Currently, when people plays various audio files by an audio device, the mode of a fixed volume is adopted to play, which can not better show the fluctuant sound effects of a song or a music that is played; the system and the method of the invention correspond the wave length of audio data with the volume, calculate the volume value according to the wavelength which is dynamically detected and then adjust the playing volume of the audio device to realize playing the same audio data with various volume, namely playing a stress with a large volume and playing a light sound with a smaller volume, thus leading the stress and the light sound of the audio data to be played dynamically by the heavy sound and the lower sound of the audio device, so as to realize the effect of fluctuant sound, thus improving the entertainment experience and hearing feeling of a user.

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 gradually improved people's living standards, and as a result, people have more and more demand for music. Especially with the continuous advancement and application of computer network technology, there have been many formats of audio files. It is very common to use computers to play audio files in various formats. 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. For example, when users want to enjoy a certain song or music, they usually have to select the volume for the song or music that needs to be played, and then The entire song or music is...
