  • 大家好！我来自南京，在 OpenHarmony 成长打算啃论文俱乐部，与 华为、软通能源、润和软件、拓维信息、深开鸿 等公司一起，学习和钻研 操作系统技术 ，
    从往年 1 月 11 日退出 OpenHarmony 俱乐部曾经有靠近 8 个月工夫了。笔者始终在思考啃论文给我带来了些什么，通过啃论文能为 OpenHarmony 做些什么。笔者利用大二升大三寒假两个月工夫移植了 Speexdsp 这个三方库到 OpenHarmony 规范零碎，而对于后面的问题我仿佛找到了答案，现将啃论文和三方库移植分享教训如下：

因为想要分享的内容较多，为防止观众姥爷们失去看上来的急躁，分享将以连载的形式进行。

本期为 移植 speexdsp 到 OpenHarmony 规范零碎 的第①期，次要内容如下：

Speexdsp

提到 Speexdsp 不得不先提到开源语音编解码器 Speex

如下是 ACM Surveys 中收录的题目为《Survey on Application-Layer Mechanisms for Speech Quality Adaptation in VoIP》综述中的一张图表。

  • 它总结了一些罕用的可变比特率编解码器，并且做了性能方面的比拟。
  • 其中惟一 Open-source 开源的两个编解码器之一就是 speex。

  • 2007 年 12 月 11 日 Speex1.2beta3 中首次将 Speex 中所有非编解码器组件（预处理器、回声打消、抖动缓冲区）都已移至新的 libspeexdsp 中。
  • 2014 年 12 月 6 日推出的 Speex 1.2rc2 和 SpeexDSP1.2rc2 正式将 speex 编解码器库和 speexDSP 库拆分为独自的源代码。

Speexdsp 性能

预处理器

预处理器被设计为在运行编码器之前在音频上应用。预处理器提供三个次要性能:

  • 噪声克制
  • 自动增益管制(AGC)
  • 语音流动检测(VAD)

自适应抖动缓冲区

  • 当通过 UDP 或 RTP 传输语音 (或任何相干内容) 时，包可能会失落，以不同的提早达到，甚至乱序。
  • 抖动缓冲区的目标是从新排序数据包，并缓冲足够长的工夫，以便它们能够被发送以进行解码。

声学回声消除器

回声打消是为了进步远端品质

  • 在任何免提通信零碎中，远端语音通过本地扬声器播放。音频在房间内流传，并被麦克风捕捉。如果从麦克风捕捉的音频被间接发送到近程端，那么用户就会听到远端语音的回声。声学回声消除器设计用于在声学回声发送到远端之前打消它。

重采样器

这个重采样器能够用于在任意两个速率之间进行转换(比率必须是有理数)，并且能够管制品质 / 复杂性的衡量。

  • 重采样器在某些状况下将音频从一个采样率转换到另一个采样率。
  • 它能够用于混合具备不同采样率的流、用于反对声卡不反对的采样率、用于转码等。

Speexdsp 移植到 OpenHarmony 规范零碎

OpenHarmony 三方库次要是基于规范 Linux 零碎的 c/c++ 开源库，所以三方库的移植工作，首先是在规范 Linux 零碎搭建环境、编译与验证，而后将三方库的编译退出到 OpenHarmony 工程的构建中。

三方库移植的次要开发步骤如下：

  1. 在规范 Linux 零碎下载三方库源码，搭建开发环境，编译整个源码工程；
  2. 剖析在规范 Linux 零碎的编译过程文件，提取编译须要的源文件、编译依赖等信息；
  3. 依据上一步剖析后果，编写 gn 文件，将三方库退出到 OpenHarmony 的编译体系；
  4. 验证编译后果，在 OpenHarmony 的 out 目录是否生成指标库；
  5. 测试 demo/ 测试单元用例执行。

一、下载源码

  • 下载三方库源码时，优先应用最新版，不要下载 master 分支，下载最新的版本分支。
    移植 speexdsp 下载的是 1.2.1 版本。

Speexdsp 源码下载地址：https://github.com/xiph/speexdsp

二、搭建开发环境，生成 Makefile 编译构建 speexdsp。

  • 不同的原生三方库提供的编译形式不雷同，依据原生三方库的 readme 文件或者 manual 用户手册能够晓得该如何编译

Speexdsp 在 linux 下的编译装置，在 linux 终端输出如下语句：

  • 装置 make 工具。

    sudo apt-get install make

  • 装置 autoAutotools 工具

    sudo apt-get install autoconf automake libtool

    GNU Autotools 框架包含三个次要的包：Autoconf，Automake，和 Libtool。

GNU 软件的构建过程，一般来说，蕴含三个步骤：
tar xfv xxx.tar.gz
./configure
make
make install
该过程个别依赖两个文件，configure 和 Makefile 文件。

  • Autoconf/Automake 就是一套用于主动构建 configure 脚本和 Makefile 文件的工具。

  • 个别应用 Makefile.am 构建的三方库，原生库中存在 autogen.sh,configure.ac 文件。由 makefile.am 主动生成 makefile。

    ./autogen.sh
  • ./autogen.sh 之后咱们能够运行./configure –help 查看 configure 配置
./configure --help
[email protected]:~/Desktop/SpeexDSP-1.2.1$ ./configure --help
`configure' configures speexdsp 1.2.1 to adapt to many kinds of systems.

Usage: ./configure [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print `checking ...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for `--cache-file=config.cache'
  -n, --no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or `..']

Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX
                          [/usr/local]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

By default, `make install' will install all the files in
`/usr/local/bin', `/usr/local/lib' etc.  You can specify
an installation prefix other than `/usr/local'using `--prefix',
for instance `--prefix=$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR            user executables [EPREFIX/bin]
  --sbindir=DIR           system admin executables [EPREFIX/sbin]

              nonstandard directory <lib dir>
  LIBS        libraries to pass to the linker, e.g. -l<library>
  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
              you have headers in a nonstandard directory <include dir>

  FFT_LIBS    linker flags for FFT, overriding pkg-config

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.

  • 在下载到 linux 中的 speexdsp 中新建 build 目录

    mkdir build

  • 运行 configure 命令来生成 Makefile。

    ./configure --prefix=/XXX/speexdsp/build -disable-sse

    SSE 是一个 X86 平台的指令集，所以要移植 speexdsp 到 OpenHarmony 过程，configure 时要 disable 掉 sse 这个配置。否则在退出 OpenHarmony 编译体系后生成 libspeexdsp_share.z.so 和在 ohos 上执行的可执行文件编译过程中会报错。

在 linux 上生成 speexdsp 的 so 动态链接库和.a 动态链接库

  • make 和 make install 后会生成 speexdsp 的.so 动态链接库和.a 动态链接库
make
make install

编译装置后 build 目录构造如下：

整个编译装置过程终端输入 log 如下：

Libraries have been installed in:
   /home/jiajiahao/Desktop/speexdsp-SpeexDSP-1.2.1/build/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the '-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the 'LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the 'LD_RUN_PATH' environment variable
     during linking
   - use the '-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to '/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

生成在 linux 上测试 speexdsp 性能用的可执行文件

编译生成出在 linux 上测试 speexdsp 性能用的可执行文件，目标是为了剖析 speexdsp 在 ohos 编译体系生成动态链接库后进功能测试的逻辑。

浏览 speexdsp 用户手册，测试 speexdsp 性能的源文件别离为：

  • testdenoise.c
  • testecho.c
  • testjitter.c
  • testresample.c
  • testresample2.c

它们均位于 speexdsp 下的 libspeexdsp。
须要把它们编译为可运行的执行文件，通过浏览用户手册能够晓得在编译时须要增加 -lspeexdsp 和 -lm

以编译 testresample 可执行文件为例，编译执行语句如下：
在 speexdsp 目录 libspeexdsp 目录下关上终端输出如下语句

gcc testjitter.c -L /home/jiajiahao/Desktop/speexdsp-SpeexDSP-1.2.1/build/lib -lspeexdsp -o testjitter -I /home/jiajiahao/Desktop/speexdsp-SpeexDSP-1.2.1/include -lm
  • 其中 /home/jiajiahao/Desktop/speexdsp-SpeexDSP-1.2.1 为笔者搁置 speexdsp 原生库 linux 下的绝对路径。
  • 链接动态链接库编译可执行文件，gcc 前面是测试用的源文件。-L 后指定 so 库所在的文件夹，-l+so 库的名字（进来 lib 和后缀）。-o 前面是可执行文件的名字，-I 前面是测试用的源文件要用到的头文件所在的地址。

编译出全副测试性能用的可执行文件如下：
