Embodiment Construction

[0053] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0054] refer to figure 1 , figure 1It is a schematic flowchart of an embodiment of a playback processing method during audio switching in the present invention. In this embodiment, the playback processing method when the audio is switched includes:

[0055] Step S10, when playing audio on the local audio device, receiving the audio data to be played sent by the external audio device;

[0056] In this embodiment, the local audio device and the external audio device are not limited. The local audio device specifically refers to the device currently playing audio, and the external audio device refers to the device that transmits the audio file to the local audio device. For example, the local audio device may be a smart TV, a smart phone, etc., and the external audio device may be a smart phone, a smart TV, and the li...

Abstract

A playing processing method and apparatus for audio switching. The method comprises: receiving audio data to be played sent from an external audio device when audio is played on a local audio device (S10); performing gain reduction processing on a gain value of corresponding audio data in local audio data (S20), and performing gain enhancement processing on a gain value of corresponding audio data in the audio data to be played (S30); and respectively outputting the local audio data subjected to the gain reduction processing and the audio data to be played subjected to the gain enhancement processing to an audio decoder on the local audio device for decoding and playing (S40). Thus, noise interference produced by audio switching between two different audio devices is avoided, and at the same time, playing after audio switching can have a smooth transition, thereby improving the user experience.

Description

technical field [0001] The invention relates to the field of audio processing, in particular to a playback processing method and device during audio switching. Background technique [0002] With the technological development of smart audio devices, different smart devices interact with each other to meet the needs of users. For example, smart TVs can realize multi-screen interaction, that is, process different program contents on different split Audio files on the smartphone are played on the smart TV. However, when the user pushes the audio file on the smart phone to the smart TV for playback, the smart TV is likely to be playing a program with sound. When the sound is suddenly switched to the audio sound pushed by the mobile phone, it is likely to cause a sudden change in the audio sound, resulting in beep noise or instantaneous interference howling sound, which not only makes the audio speaker on the TV end prone to damage, but also reduces the use of experience. Cont...
