Audio acquisition method, audio playing method, system and equipment and storage medium

Abstract

The embodiment of the invention discloses an audio collection method, an audio playing method, an audio playing system, audio collection equipment and a storage medium. The audio collection method comprises the steps that an audio input and output interface in a hardware abstraction module calls a kernel in response to a calling request when an audio application program collects audio; the kerneldrives the audio acquisition equipment to acquire audio signals; The core transmits the audio signal acquired by the audio acquisition equipment to the audio input / output interface; And the audio input / output interface transmits the audio signal to the audio application program. According to the embodiment of the invention, the audio acquisition and playing time delay can be reduced.

Description

technical field [0001] Embodiments of the present invention relate to audio processing technologies, and in particular to an audio collection method, an audio playback method, a system, a device, and a storage medium. Background technique [0002] In application scenarios such as voice calls, audio and video calls, and playing music, audio signals need to be collected or played. combine Figure 1a , the existing audio system based on the Android system includes, from top to bottom, an audio application program, an application framework, an audio service, a hardware abstraction module, a kernel, and an audio device. [0003] At present, the audio signal acquisition process based on the above audio system includes: an audio device (such as a microphone) collects the audio signal, and transmits it to the kernel and the hardware abstraction module in turn, and the hardware abstraction module copies the audio signal to the local cache, and the local cache then Sent to the audio ...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that the current audio signal acquisition and playback process needs to be processed by multiple system modules, and needs to be copied to the local cache multiple times, resulting in the introduction of too much time delay, and the real-time performance of the audio playback and acquisition process is poor.
