Embodiment Construction

[0024] The present invention adds background sound to audio data in real time in the Native layer, without the need for the application program itself to have the function of adding background sound, so the present invention overcomes the limitations brought about by adding background sound to audio data at the application layer.

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0026] The embodiment of the present invention provides a kind of audio data processing method, refer to below figure 2 and image 3 The method described in this example will be described. in, figure 2 It is a flowchart of an audio data processing method according to an embodiment of the present invention. image 3 It is a schematic diagram of the audio data p...

Abstract

The invention discloses an audio data processing method and device. In a Native layer, the method comprises the steps of reading first audio data collected by an audio input device from a drive layer in real time; carrying out audio mixing on the first audio data and preset first audio data, thereby obtaining audio mixed data; and sampling the audio mixed data and transmitting the sampled audio mixed data to an application of an application layer. According to the method and the device, a background audio can be added to the first audio data in real time within the Native layer, and the application needs to have a recording function and does not need to have a background audio adding function, so the limitation resulting from adding the background audio to the first audio data in the application layer is overcome.

Description

technical field [0001] The invention relates to the technical field of instant communication, in particular to an audio data processing method and device. Background technique [0002] With the advancement of network technology and mobile Internet, instant messaging technology has developed rapidly, such as WeChat, Skype, Line and other applications have emerged as the times require. However, in some specific occasions and specific times, users need to forge their own scene to protect personal privacy. In order to achieve this effect, it is necessary to add background sound during the voice chat, such as the noise of the train station, the singing of KTV, the sound of waves on the seashore, and so on. [0003] In the prior art, some application programs for recording can add background sound to audio data, and its implementation principle is as follows: figure 1 As shown, after the recording application of the application layer is started, a recording thread corresponding ...
