Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in 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.

[0024] figure 1 It is a flow chart of an audio data sending method in an embodiment, and the audio data sending method can be implemented at a sending end of an analog audio signal. see figure 1 , the audio data sending method includes the following steps.

[0025] S110, generating a start synchronization code and outputting it through an audio port.

[0026] The generated start synchronization code is a series of equal-amplitude waveform signals with fixed frequency and phase. Specifically, first generate a fixed bit stream, such as 010101...bit. The fixed bit stream is loaded on two sets of ...

Abstract

The invention relates to an audio data transmitting method. The method includes generating a start synchronization code and outputting the start synchronization code through an audio port; converting to-be-sent digital audio signals to analog audio signals and outputting the analog audio signals through the audio port; generating an end synchronization code and outputting the end synchronization code through the audio port, wherein the start synchronization code and the end synchronization code are both analog audio waveform signals having fixed frequencies and phases. The method provided by the invention can ensure normal receiving of the audio data. The invention also relates to an audio data receiving method.

Description

technical field [0001] The invention relates to the technical field of audio communication, in particular to a method for sending and receiving audio data. Background technique [0002] With the rapid development of audio communication technology, more and more devices use audio ports to communicate with audio devices. In the traditional audio communication process, the audio sending end directly sends audio data to the audio receiving end. When the commonly used audio devices such as mobile phones and tablets start to play audio, the sound will be distorted to a certain extent, which will affect the normal reception of data and further affect the quality of communication. Contents of the invention [0003] Based on this, it is necessary to provide an audio data sending method that can ensure that the audio data can be received normally. [0004] It also relates to an audio data receiving method. [0005] A method for sending audio data, comprising: generating a start s...
