Abstract

The invention provides a multi-audio output method and device. The method includes the following steps: a processor receives multiple groups of audio stream data, classifies the audio stream data according to preset configuration information, re-samples and mixes the audio streams belonging to the same type of output to get mixed data, synthesizes the mixed data or the unmixed audio stream data according to a preset synthesis rule to get audio synthesis data, and transmits the audio synthesis data to an audio codec; and the audio codec receives the audio synthesis data, separates the audio synthesis data according to a separation rule corresponding to the preset synthesis rule, and transmits the separated mixed data or the unmixed audio stream data to corresponding output equipment for output. According to the invention, equipment with a single audio output interface is enabled to simultaneously and separately output multiple pieces of audio. The hardware cost is effectively reduced, and the user experience is enhanced.

Description

Technical field [0001] The present invention relates to the field of audio output processing, in particular to a multi-audio output method and device. Background technique [0002] With the penetration of intelligent systems into various fields, the configuration of hardware devices has also been increasing, and a single device needs to take into account different scenarios at the same time. Among them, the use of separate output for multiple audio is particularly critical. [0003] Such as figure 1 As shown, in order to support multiple audio output in an existing single device, it is usually necessary to have multiple audio output interfaces at the same time, such as having two sets of I2S, or having one set of I2S and one set of PCM interfaces, which is costly. When the audio output interface has pin multiplexing or the device does not have so many audio output interfaces, the function of simultaneous output of multiple audio and different hardware cannot be completed, which af...
