Problems solved by technology

[0003] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: the existing audio interception software requires us to provide audio files and play them through music players to achieve interception, but many times we play sounds without Played through these music players, such as chatting voice messages on some social software, watching videos online or listening to sound clips in music, often cannot be intercepted by these interception tools, because most of the audio information in these software is After encryption, it cannot be directly cracked, so these sound clips cannot be intercepted and saved

Embodiment 1

[0035] refer to figure 1 , which shows an audio interception method provided by an embodiment of the present invention, the method includes the following steps:

[0036] S1. Modify the sound device driver and application programming interface to obtain an encapsulation layer;

[0037] Specifically, in this embodiment and subsequent embodiments, unless otherwise specified, audio interception on a mobile phone is taken as an example. Encapsulate the original sound device driver to obtain an encapsulation layer. The encapsulation hides the attributes and implementation details of the object, only exposes the interface to the outside world, and controls the access level of reading and modifying the attributes in the program; the abstracted The combination of data and behavior (or function) forms an organic whole, that is, the organic combination of data and source code for operating data forms a "class", in which both data and functions are members of the class.

[0038] S2. Cal...

Embodiment 2

[0049] Embodiment 2 of the present invention is specifically based on Embodiment 1.

[0050] In the embodiment of the present invention, the encapsulation layer in this embodiment will directly call the original device driver to play the audio file, so as to obtain the played audio file, and can also obtain information such as the playing position.

[0051] In the embodiment of the present invention, a step of presetting a specific storage space is also included, for temporarily writing the audio file information of the encapsulation layer into the specific storage space.

[0052] In the embodiment of the present invention, when the user uses the software to play the sound, the mobile phone operating system will call the encapsulation layer first, and then the encapsulation layer will call the original sound drive device to play the sound. The information will be temporarily written into the preset specific storage space.

[0053] In the embodiment of the present invention, f...

Embodiment 3

[0058] refer to figure 2 , the figure shows an audio interception device provided by an embodiment of the present invention, wherein the device includes an encapsulation module 1, an interception processing module 2, and a storage module 3;

[0059] The encapsulation module 1 is used to modify the original sound device driver and application programming interface to obtain an encapsulation layer; the encapsulation module 1 is arranged on the kernel layer of the mobile phone operating system, and the original sound device driver and application The program programming interface is modified to obtain an encapsulation layer. This encapsulation layer can directly call the original device driver to play the sound, and can also obtain information such as the audio file and the playback position, and temporarily write the information such as the audio file and the playback position into the storage module 3 .

[0060] The interception processing module 2 is used for intercepting, l...

Abstract

The invention relates to an audio capture method and a device. The method comprises steps that a sound equipment driving program and an application program programming interface are modified to acquire a packaging layer; the modified application program programming interface of the packaging layer is called, and an audio file played by sound equipment is acquired; the acquired audio file played by sound equipment is temporarily stored in a special storage space; according to audio capture triggering operation, the audio file in the special storage space is captured; the captured audio file is played or stored. According to the method, any sound segment of a handset or a flat computer can be conveniently captured, a wide application scope and operation convenience are realized, the sound information segment can be consistent with an original file in timbre, the timbre effect is prevented from becoming bad, great change of a user interface of the handset is not required, technical realization is convenient, user operation steps are simplified, and user operation is easier.

Description

technical field [0001] The embodiments of the present invention belong to the technical field of communication, and in particular relate to an audio interception method and device. Background technique [0002] Nowadays, mobile phones and tablets are more and more popular, and many functions related to music playback are provided on mobile phones and tablets, such as the interception function of music clips. [0003] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: the existing audio interception software requires us to provide audio files and play them through music players to achieve interception, but many times we play sounds without Played through these music players, such as chatting voice messages on some social software, watching videos online or listening to sound clips in music, often cannot be intercepted by these interception tools, because most of the audio information in these ...
