Embodiment 1

[0044] like figure 1 As shown, the present embodiment provides a method for generating an audio segment, which can be applied to a player, specifically, can be applied to a network media player with an audio editing function, and the method includes the following steps:

[0045] Step S110, acquiring an audio file.

[0046] Optionally, the step of obtaining the audio file may include the following sub-steps:

[0047] Step S110-1, loading an audio file.

[0048] Specifically, the audio file is a variable bit rate VBR (Variable Bit-Rate) audio file, and a complete variable bit rate audio file is loaded to the player. For example, the audio file may be a paid song obtained through the network. The higher the bit rate, the better the sound quality. Generally speaking, the higher the pitch of the audio clip, the more space is needed to store it, and the higher the bit rate, VBR encoding technology selects the most suitable frame for each audio frame. For audio frames with a lower...

Embodiment 2

[0081] like figure 2 As shown, the present embodiment provides a device for generating audio clips, including the following modules:

[0082] Obtaining module 210, configured to obtain audio files.

[0083] The detection module 220 is configured to detect the code stream change of the audio file.

[0084] The generating module 230 is configured to generate a target audio segment by using a preset code stream range and a preset duration.

[0085] It can be understood that the acquisition module 210 can be used to execute step S110 in the first embodiment, the detection module 220 can be used to execute the step S120 in the first embodiment, and the generation module 230 can be used to execute the step S130 in the first embodiment. For the details of the specific steps, refer to Embodiment 1, which will not be repeated here.

[0086] Further, when the generation module 230 is used to generate the target audio segment by using the preset code stream range and the preset durat...

Embodiment 3

[0100] The present invention provides a player, including: a memory and a processor, where a computer program is stored on the memory, and when the computer program is executed by the processor, the method for generating an audio segment provided in Embodiment 1 is realized.

[0101] In this embodiment, the player may be a network media player, and the processor may be an application specific integrated circuit (Application Specific Integrated Circuit, ASIC for short), a digital signal processor (Digital Signal Processor, DSP for short), or a digital signal processing device (Digital Signal Processor). Processing Device, referred to as DSPD), programmable logic device (Programmable Logic Device, referred to as PLD), field programmable gate array (Field Programmable Gate Array, referred to as FPGA), controller, microcontroller, microprocessor or other electronic components to achieve , for executing the method for generating an audio clip in the above embodiment. For the method...

Abstract

The present invention provides an audio clip generation method, device, player and storage medium. The audio clip generation method includes: acquiring an audio file; detecting changes in the code stream of the audio file; using a preset code stream range and a preset duration to generate the target audio clip. The problem of generating audio clips that meet preset requirements is solved so that users can experience the charm of the entire audio through the audio clips. By detecting the code stream change of the acquired audio file, using the preset code stream range and preset duration, an audio segment meeting the preset conditions is generated, and the climax part of the audio file (such as a song) is saved as a segment to realize In order to automatically and quickly identify the climax part in the audio file, help users quickly preview the highlights in the audio, and let the user feel the charm of the entire audio by reflecting the audio clip of the climax part.

Description

technical field [0001] The invention belongs to the technical field of audio processing, and in particular relates to an audio clip generation method, device, player and storage medium. Background technique [0002] With the continuous popularization of Internet technology, the Internet multimedia music version is gradually accepted by Chinese users. More and more clients allow free users to listen to a short piece of music, allowing users to decide whether they want to use this small piece of music. Buying singles can also save users a lot of time in choosing music. [0003] In the prior art, the client simply stops the previous 10s or 15s for the user, and the user cuts the song before he really feels the charm of the song. Therefore, there is an urgent need in this field to generate audio clips that meet the preset requirements. , to allow users to experience the charm of the entire audio through audio clips. Contents of the invention [0004] The present invention pr...
