集成AECM模块

1.通过 webrtc官网下载需要模块\modules\audio_processing\aecm
2.新建eclipse工程,新建jni文件夹将webrtc aecm模块拷贝到jni文件夹下

3.编写本地接口

package com.wrtcmy.webrtc.aecm;/*** This class supports the acoustic echo cancellation for mobile edition. Please <b>bug me</b> if you find any bugs in* this toolkit.<br>* <br>* <b>[Notice]</b><br>* 1. there are 5 more native interface that I'm not trying to provide in this MobileAEC toolkit.<br>* But I think I should mention it out as a list below, for secondary development if necessary: <br>* <ul>* <li>WebRtc_Word32 WebRtcAecm_get_config(void *, AecmConfig *);</li>* <li>WebRtc_Word32 WebRtcAecm_InitEchoPath(void* , const void* , size_t);</li>* <li>WebRtc_Word32 WebRtcAecm_GetEchoPath(void* , void* , size_t);</li>* <li>size_t WebRtcAecm_echo_path_size_bytes();</li>* <li>WebRtc_Word32 WebRtcAecm_get_error_code(void *);</li>* </ul>* 2. if you are working on an android platform, put the shared library "libwebrtc_aecm.so"<br>* into path "/your project/libs/armeabi/", if the dir does not exist, you should create it, otherwise you<br>* will get a "unsatisfied link error" at run time.<br>* 3. you should always call <b>close()</b> method <b>manually</b> when all things are finished.<br>* <br>* <b>[Usage]</b> <br>* <ul>* 1. You create a MobileAEC object first(set the parameters to constructor or null are both Ok, if null are set, then* we will use default values instead).<br>* 2. change the aggressiveness or sampling frequency of the AECM instance if necessary.<br>* 3. call <b>prepare()</b> method to make the AECM instance prepared. <br>* 4. then call "farendBuffer" to set far-end signal to AECM instance. <br>* 5. now you call "echoCancellation()" to deal with the acoustic echo things.<br>* The order of step 1,2,3,4 and 5 is significant, when all settings are done or you changed previous<br>* settings, <b>DO NOT</b> forget to call prepare() method, otherwise your new settings will be ignored by AECM* instance. <br>* 6. finally you should call <b>close()</b> method <b>manually</b> when all things are done, after that, the AECM* instance is no longer available until next <b>prepare()</b> is called.<br>* </ul>* * @version 0.1 2013-3-8* */

}

4.在jni文件夹下新建Android.mk与Application.mk并在对应模块下新建Android.mk
Android.mk

include $(call all-subdir-makefiles)

Application.mk

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
APP_PROJECT_PATH := $(call my-dir)/../
APP_STL := gnustl_staticAPP_BUILD_SCRIPT:=$(call my-dir)/Android.mk
APP_PLATFORM := android-22
APP_ABI := armeabi-v7a,armeabi
APP_CFLAGS:=-DDISABLE_NEON

aecm\Android.mk

LOCAL_PATH := $(call my-dir)include $(CLEAR_VARS)LOCAL_MODULE := webrtc_aecm
LOCAL_CFLAGS += -DWEBRTC_POSIX
LOCAL_SRC_FILES := \randomization_functions.c \spl_sqrt_floor.c \division_operations.c \vector_scaling_operations.c \downsample_fast.c \cross_correlation.c \spl_init.c \min_max_operations.c \complex_fft.c \complex_bit_reverse.c \real_fft.c \delay_estimator.c \delay_estimator_wrapper.c \ring_buffer.c \aecm_core.c \echo_control_mobile.c \com_wrtcmy_webrtc_aecm_AECM.c#aecm_wrapper.cLOCAL_LDLIBS :=-lloginclude $(BUILD_SHARED_LIBRARY)

5.编译生成头文件可参考: Android源码下编译apk、jar与jni ndk-build
6.通过c文件实现

集成NS模块

流程严格按照AECM模块只列出不同地方

源码文件在\modules\audio_processing\ns
