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...
