third_party_sonic

使用场景

Sonic是一个用于音频变速的算法，可以实现音频变速不变调、变调不变速、同时变速变调等基本音频处理，尤其对2倍以上的变速进行了优化。Sonic包含了C和Java两种实现，main.c和main.java分别为两者的简单使用示例。

架构说明

在OpenHarmony系统中，sonic继承在音频服务中，通过音频服务提供接口，应用可以调用相关接口实现音频变速播放。相关接口为setSpeed与getSpeed, 详细说明参考链接: https://gitee.com/openharmony/docs/blob/master/zh-cn/application-dev/reference/apis-audio-kit/js-apis-audio.md

OpenHarmony对于sonic的适配

sonic引入openharmony的thirdparty目录下，使用OpenHarmony中依赖部件的方式进行编译。

主干代码下载

repo init -u https://gitee.com/openharmony/manifest.git -b master --no-repo-verify
repo sync -c
repo forall -c 'git lfs pull'

在使用的模块进行依赖

deps = [ "//third_party/sonic:sonic" ]

预处理

./build/prebuilts_download.sh

编译

./build.sh --product-name rk3568 --ccache
