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。
Speexdsp源碼下載地址：https://github.com/xiph/speexdsp
二、搭建開發環境，生成Makefile編譯構建speexdsp。
（筆者使用的linux環境是Ubuntu18.04，不推薦Ubuntu22.04下編譯因為編譯不了）
- 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 Autotools構建過程如下
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]
--oldincludedir=DIR C header files for non-gcc [/usr/include]
--datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
--datadir=DIR read-only architecture-independent data [DATAROOTDIR]
--infodir=DIR info documentation [DATAROOTDIR/info]
--localedir=DIR locale-dependent data [DATAROOTDIR/locale]
--mandir=DIR man documentation [DATAROOTDIR/man]
--docdir=DIR documentation root [DATAROOTDIR/doc/speexdsp]

choices are kiss (default fixed point), smallft
(default floating point), gpl-fftw3 and
proprietary-intel-mkl
Some influential environment variables:
CC C compiler command
CFLAGS C compiler flags
LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
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>
LT_SYS_LIBRARY_PATH
User-defined run-time library search path.
CPP C preprocessor
PKG_CONFIG path to pkg-config utility
PKG_CONFIG_PATH
directories to add to pkg-config's search path
PKG_CONFIG_LIBDIR
path overriding pkg-config's built-in search path
FFT_CFLAGS C compiler flags for FFT, overriding pkg-config
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：

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：
