Problems solved by technology

In fact, people often want to enjoy music, not in a "non-concentrated state", and deliberately changing the volume will affect the appreciation effect. This is because the audio structure of the audio unit part of media files (especially music files) is generally After design, the sound levels and ups and downs of various stages are a whole. If the volume is modified during playback, the original design will be changed, which may cause the volume of the first half and the second half of an audio unit to be different. , so that users will never hear the style of the original music, especially for music enthusiasts, it will affect the auditory experience of listening to music

Embodiment 1

[0022] Referring to FIG. 1, it is a schematic flowchart of Embodiment 1 of the method for playing a media file of the present invention, which includes the steps:

[0023] Step S101: Predetermined reference volume value and predetermined reference difference value, wherein the determination of the predetermined reference volume value can be determined according to the volume value of the best comfort level acceptable to the human ear, in addition, since the volume value of the sound varies within a certain range In the case of , the human ear will not be able to distinguish the change of the volume value, therefore, the predetermined reference difference value can be determined according to the change range;

[0024] Step S102: Determine whether the difference between the volume value of the audio unit and the predetermined reference volume value, that is, the absolute value of the difference between the volume value of the audio unit and the predetermined reference volume valu...

Embodiment 2

[0042] Referring to FIG. 2, it is a schematic flowchart of Embodiment 2 of the method for playing a media file of the present invention. In this embodiment, the predetermined reference difference is 0. When judging the volume value of the audio file, the Taking the predetermined reference volume value as the judgment criterion, when the volume value of the audio unit is not equal to the predetermined reference volume value, the reference volume value is directly set as the volume setting value of the audio unit.

[0043] In addition, since the external environment noise during playback of audio files may be different, as a further improvement, the user can manually adjust the volume of a single audio unit, all audio units, or even multiple audio files or audio units in it to increase the volume. and volume down operations.

[0044] The other technical features of this embodiment are the same as those of the first embodiment, and are not repeated here.

Embodiment 3

[0046] Referring to FIG. 3, it is a schematic flowchart of Embodiment 3 of the method for playing a media file of the present invention. In this embodiment, the setting of the volume setting value of the audio unit is performed in the process of playing the media file, Include steps:

[0047] Step S301: preset a predetermined reference volume value and a predetermined reference difference value, wherein the setting methods of the predetermined reference volume value and the predetermined reference difference value can be the same as those in the first embodiment;

[0048] Step S302: start playing each audio unit, and enter step S303;

[0049] Step S303: determine whether the absolute value of the difference between the volume value of the audio unit to be played and the predetermined reference volume value is less than or equal to the predetermined reference difference, if so, go to step S305, if not, go to step S304;

[0050] Step S304: Set a volume setting value for the aud...

Abstract

The present invention discloses a media playing method and device. By presetting a preset reference volume value and a reference difference value and according to the volume value of the audio unit of a media file, the present invention adjusts the volume of the audio unit of the media file so that the sound effects of the media file with different sound volumes are basically the same, without too loud or too small volume and without changing the original audio structure of the audio unit. The media playing method and device of the present invention can be applied to equipment with playing function such as a CD player, an MP3, an MP4, a mobile phone and a computer etc.

Description

technical field [0001] The present invention relates to a method and device for playing media files, in particular to a method and device for playing audio files which can improve the auditory effect by adjusting the playing volume. Background technique [0002] With the development of electronic information technology, various digital products emerge in an endless stream, such as CD, MP3, MP4, etc. Using computers or portable media players to enjoy music and watch video images has become a part of people's lives, so the functions of music playback and video playback It has gradually become two basic functions of many electronic products, and it has become an important trend to enjoy music or video files for a long time. With the continuous development of technology, the price of players is getting lower and lower, and the performance of new products has been greatly improved in all aspects, especially the appearance, practicality and sound effects of the products. However,...
