由于想要分享的內容較多，為避免觀眾姥爺們失去看下去的耐心，分享將以連載的方式進行。

本期為移植speexdsp到OpenHarmony標準系統的第①期，主要內容如下：

Speexdsp

提到Speexdsp不得不先提到開源語音編解碼器Speex

如下是ACM Surveys中收錄的標題為《Survey on Application-Layer Mechanisms for Speech Quality Adaptation in VoIP》綜述中的一張圖表。

它總結了一些常用的可變比特率編解碼器，并且做了性能方面的比較。
其中唯一Open-source開源的兩個編解碼器之一就是speex。

2007年12月11日Speex1.2beta3中首次將Speex中所有非編解碼器組件（預處理器、回聲消除、抖動緩沖區）都已移至新的libspeexdsp中。
2014年12月6日推出的Speex 1.2rc2和SpeexDSP1.2rc2正式將speex編解碼器庫和speexDSP庫拆分為單獨的源代碼。

Speexdsp功能

預處理器

預處理器被設計為在運行編碼器之前在音頻上使用。預處理器提供三個主要功能:

噪聲抑制
自動增益控制(AGC)
語音活動檢測(VAD)

自適應抖動緩沖區

當通過UDP或RTP傳輸語音(或任何相關內容)時，包可能會丟失，以不同的延遲到達，甚至亂序。
抖動緩沖區的目的是重新排序數據包，并緩沖足夠長的時間，以便它們可以被發送以進行解碼。

聲學回聲消除器

回聲消除是為了提高遠端質量

在任何免提通信系統中，遠端語音通過本地揚聲器播放。音頻在房間內傳播，并被麥克風捕獲。如果從麥克風捕獲的音頻被直接發送到遠程端，那么用戶就會聽到遠端語音的回聲。聲學回聲消除器設計用于在聲學回聲發送到遠端之前消除它。

重采樣器

這個重采樣器可以用于在任意兩個速率之間進行轉換(比率必須是有理數)，并且可以控制質量/復雜性的權衡。

重采樣器在某些情況下將音頻從一個采樣率轉換到另一個采樣率。
它可以用于混合具有不同采樣率的流、用于支持聲卡不支持的采樣率、用于轉碼等。

Speexdsp移植到OpenHarmony標準系統

OpenHarmony三方庫主要是基于標準 Linux 系統的 c/c++ 開源庫，所以三方庫的移植工作，首先是在標準 Linux 系統搭建環境、編譯與驗證，然后將三方庫的編譯加入到 OpenHarmony 工程的構建中。

三方庫移植的主要開發步驟如下：

在標準Linux系統下載三方庫源碼，搭建開發環境，編譯整個源碼工程；
分析在標準Linux系統的編譯過程文件，提取編譯需要的源文件、編譯依賴等信息；
根據上一步分析結果，編寫gn文件，將三方庫加入到OpenHarmony的編譯體系；
驗證編譯結果，在OpenHarmony的out目錄是否生成目標庫；
測試demo/測試單元用例執行。

一、下載源碼

下載三方庫源碼時，優先使用最新版，不要下載master分支，下載最新的版本分支。
移植speexdsp下載的是1.2.1版本。

二、搭建開發環境，生成Makefile編譯構建speexdsp。

不同的原生三方庫提供的編譯方式不相同，根據原生三方庫的readme文件或者manual用戶手冊可以知道該如何編譯

Speexdsp在linux下的編譯安裝，在linux終端輸入如下語句：

安裝make工具。

sudo apt-get install make

安裝autoAutotools工具

sudo apt-get install autoconf automake libtool

GNU Autotools框架包括三個主要的包：Autoconf，Automake，和Libtool。

GNU軟件的構建過程，一般來說，包含三個步驟：
tar xfv xxx.tar.gz
./configure
make
make install
該過程一般依賴兩個文件， configure和Makefile文件。

Autoconf/Automake就是一套用于自動構建configure腳本和Makefile文件的工具。

一般使用Makefile.am構建的三方庫，原生庫中存在autogen.sh,configure.ac文件。由makefile.am自動生成makefile。

./autogen.sh

./autogen.sh之后我們可以運行./configure --help查看configure配置

./configure --help

jiajiahao@ubuntu:~/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]
  --libexecdir=DIR        program executables [EPREFIX/libexec]
  --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
  --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
  --runstatedir=DIR       modifiable per-process data [LOCALSTATEDIR/run]
  --libdir=DIR            object code libraries [EPREFIX/lib]
  --includedir=DIR        C header files [PREFIX/include]

  --docdir=DIR            documentation root [DATAROOTDIR/doc/speexdsp]
  --htmldir=DIR           html documentation [DOCDIR]
  --dvidir=DIR            dvi documentation [DOCDIR]
  --pdfdir=DIR            pdf documentation [DOCDIR]
  --psdir=DIR             ps documentation [DOCDIR]

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

在下載到linux中的speexdsp中新建build目錄

mkdir build

運行configure命令來生成Makefile。

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

SSE是一個X86平臺的指令集，所以要移植speexdsp到OpenHarmony過程，configure時要disable掉sse這個配置。否則在加入OpenHarmony編譯體系后生成libspeexdsp_share.z.so和在ohos上執行的可執行文件編譯過程中會報錯。

在linux上生成speexdsp的so動態鏈接庫和.a靜態鏈接庫

make和make install后會生成speexdsp的.so動態鏈接庫和.a靜態鏈接庫

make
make install

編譯安裝后build目錄結構如下：

整個編譯安裝過程終端輸出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上測試speexdsp功能用的可執行文件

編譯生成出在linux上測試speexdsp功能用的可執行文件，目的是為了分析speexdsp在ohos編譯體系生成動態鏈接庫后進功能測試的邏輯。

閱讀speexdsp用戶手冊，測試speexdsp功能的源文件分別為：

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

它們均位于speexdsp下的libspeexdsp。
需要把它們編譯為可運行的執行文件，通過閱讀用戶手冊可以知道在編譯時需要添加-lspeexdsp和-lm

以編譯testresample可執行文件為例，編譯執行語句如下：
在speexdsp目錄libspeexdsp目錄下打開終端輸入如下語句

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為筆者放置speexdsp原生庫linux下的絕對路徑。
鏈接動態鏈接庫編譯可執行文件，gcc后面是測試用的源文件。-L 后指定so庫所在的文件夾，-l+so庫的名字（出去lib和后綴）。-o 后面是可執行文件的名字，-I 后面是測試用的源文件要用到的頭文件所在的地址。

編譯出全部測試功能用的可執行文件如下：
