Audio communication method and device

Abstract

The invention discloses an audio communication method and device. A chain table corresponding to an audio mixer is set up through host equipment, and a data modulation audio carrier signal needed to be outputted through an audio interface is generated into a modulation sound signal; audio signals including the modulation sound signal acting as input sources of the audio mixer are outputted to the audio mixer, and all the input sources are converted into the unified audio sample frequency before audio mixing; on account of two different kinds of accumulative algorithms during the audio mixing of the audio mixer, the input sources adopt different audio single input manners respectively; the signals of all the input sources through accumulative audio mixing acting as a result of audio mixing are outputted by the audio mixer; and the method and the device have the benefits that under the condition of not modifying the audio setting of the host equipment or not affecting the operation of other programs of the host equipment, the background sound which performs data communication through adopting the audio interface is suppressed; and as the solution is realized through a software, the method and the device have better compatibility and generality.

Description

technical field [0001] The present invention relates to the technical field of audio processing, in particular to an audio communication method and device. Background technique [0002] When host devices such as smart phones and tablets communicate data with some external audio communication devices such as USBKey through the audio interface, the data communication function is realized by modulating the audio data; but in practical applications, there are usually the following problems, in During the communication between the host device and the external audio communication device through the audio interface, it will be interfered by the sound played by other application programs on the host, thus causing communication errors or communication failures. In view of the above situation, the commonly used solution at present is: when the above-mentioned host equipment communicates with some external audio communication equipment, modify the sound settings of the host and other p...
