Abstract

The invention provides a method and device for processing input audio data in an Android system. The method for processing the input audio data includes the steps that after the audio data reported by target equipment is received, the audio data is reported to an audio data entity AudioFlinger process to be switched into write buffer; audio mixing operation of left and right vocal tracts is performed on the audio data written into the buffer; the audio data after audio mixing is read and written into a pulse code modulation (PCM) audio driver of the Android system. According to the embodiment, only the audio data of the preset type is considered, in this way, it is avoided that audio data of all types is compatible with the Android system, so that delay occurs, the requirements for low-delay scenes are met, and user experience is improved; inter-process communication cost of the Android system can be further reduced, and the processing efficiency of the Android system is improved.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a method and device for processing input audio data in an Android system. Background technique [0002] In some interactive scenarios, multiple mobile devices with Android system are usually configured for wireless interconnection. For example, in the singing scene, configure the microphone and speakers to connect with each other through Bluetooth. [0003] After the Android system receives the Bluetooth audio data of a mobile device, it analyzes the protocol through the "Bluetooth protocol stack", and then writes the above audio data packet to the virtual device node UHID of the driver layer. The core service of the Android system is the audio data entity AuduiFlinger to process the above audio data, send each sampled audio packet to a different thread for mixing, and then send it to the process that processes the audio data for processing and output. [0004...
