data/attach/1907/zl18sf7hcgyh2pv2x1hgaeyqq2k3chdh.jpg 模块一体验使用fmod 到https://www.fmod.com/download 上下载fmod android版本的

这里我们用的是别人生成的so库 libfmod.so库 libfmodL.so库
操作步骤 1.在assets中存三个音频由之前的fmod使用，我们可以知道音频会从assets中去取 file:///android_asset/

const char *Common_MediaPath(const char *fileName)
{
    char *filePath = (char *)calloc(256, sizeof(char));
    strcat(filePath, "file:///android_asset/");
    strcat(filePath, fileName);
    gPathList.push_back(filePath);
    return filePath;
}

2.在main目录下新建jni文件夹将 D:fmodstudioapi11001androidfmodstudioapi11001androidapilowlevel 下的inc考入

3.playsound.cpp是主要文件我们从D:fmodstudioapi11001androidfmodstudioapi11001androidapilowlevelexamples下获取

4.导入其他文件 common.h common.cpp common_platform.h common_platform.cpp ===================上面都是最基本的 effects.cpp 控制音效的 (其中记得把导包的路径修改)

5.从java文件中的MainActivity替换新建项目的MainActivity以及包名

6.将lib下的东西考入并导包 fmod.jar以及不同cpu的so库

7.Android.mk文件

LOCAL_PATH := $(call my-dir)


include $(CLEAR_VARS)
LOCAL_MODULE := fmod
LOCAL_SRC_FILES := libfmod.so
include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE := fmodL
LOCAL_SRC_FILES := libfmodL.so
include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)

LOCAL_MODULE    := qq_voicer
LOCAL_SRC_FILES := play_sound.cpp common.cpp common_platform.cpp
LOCAL_SHARED_LIBRARIES := fmod fmodL
LOCAL_LDLIBS := -llog
include $(BUILD_SHARED_LIBRARY)

上面两个是我们依赖的so库最后面一个 LOCAL_SRC_FILES 是我们需要依赖的cpp文件 LOCAL_LDIBS是允许日志输出
8.Application.mk

APP_STL := gnustl_static
APP_ABI := all

运行效果

模块二仿QQ变声就是在原有基础上多加些东西channel给原生音频加上特效

1）新建EffectUtils.java

package org.fmod.example;

/**
 * Created by Boom on 2017/11/27.
 */

public class EffectUtils {

    //音效类型
    public static final int MODE_NORMAL = 0;
    public static final int MODE_LUOLI = 1;
    public static final int MODE_DASHU = 2;
    public static final int MODE_JINGSONG = 3;
    public static final int MODE_GAOGUAI = 4;
    public static final int MODE_KONGLING = 5;
    /**
     * 音效处理
     * @param path
     * @param type
     */
    public native static void fix(String path,int type);

    static {
        System.loadLibrary("qq_voicer");
    }
}

2）javah生成头文件 org_fmod_example_EffectUtils.h

/* DO NOT EDIT THIS FILE - it is machine generated */
#include 
/* Header for class org_fmod_example_EffectUtils */

#ifndef _Included_org_fmod_example_EffectUtils
#define _Included_org_fmod_example_EffectUtils
#ifdef __cplusplus
extern "C" {
#endif
#undef org_fmod_example_EffectUtils_MODE_NORMAL
#define org_fmod_example_EffectUtils_MODE_NORMAL 0L
#undef org_fmod_example_EffectUtils_MODE_LUOLI
#define org_fmod_example_EffectUtils_MODE_LUOLI 1L
#undef org_fmod_example_EffectUtils_MODE_DASHU
#define org_fmod_example_EffectUtils_MODE_DASHU 2L
#undef org_fmod_example_EffectUtils_MODE_JINGSONG
#define org_fmod_example_EffectUtils_MODE_JINGSONG 3L
#undef org_fmod_example_EffectUtils_MODE_GAOGUAI
#define org_fmod_example_EffectUtils_MODE_GAOGUAI 4L
#undef org_fmod_example_EffectUtils_MODE_KONGLING
#define org_fmod_example_EffectUtils_MODE_KONGLING 5L
/*
 * Class:     org_fmod_example_EffectUtils
 * Method:    fix
 * Signature: (Ljava/lang/String;I)V
 */
JNIEXPORT void JNICALL Java_org_fmod_example_EffectUtils_fix
  (JNIEnv *, jclass, jstring, jint);

#ifdef __cplusplus
}
#endif
#endif

3）模仿effects.cpp文件自定义 effectfix.cpp文件

#include "inc/fmod.hpp"

#include 
#include 
#include "org_fmod_example_EffectUtils.h"

#include 
#define LOGI(FORMAT,...) __android_log_print(ANDROID_LOG_INFO,"jason",FORMAT,##__VA_ARGS__);
#define LOGE(FORMAT,...) __android_log_print(ANDROID_LOG_ERROR,"jason",FORMAT,##__VA_ARGS__);

#define MODE_NORMAL 0
#define MODE_LUOLI 1
#define MODE_DASHU 2
#define MODE_JINGSONG 3
#define MODE_GAOGUAI 4
#define MODE_KONGLING 5

using namespace FMOD;

JNIEXPORT void JNICALL Java_org_fmod_example_EffectUtils_fix
  (JNIEnv *env, jclass jcls, jstring path_jstr, jint type){
	System *system;
	Sound *sound;
	Channel *channel;
	DSP *dsp;
	bool playing = true;
	float frequency = 0;

	const char* path_cstr = env->GetStringUTFChars(path_jstr,NULL);
	LOGI("%s",path_cstr);
	try {
		//初始化
		System_Create(&system);
		system->init(32, FMOD_INIT_NORMAL, NULL);

		//创建声音
		system->createSound(path_cstr, FMOD_DEFAULT, NULL, &sound);
		switch (type) {
			case MODE_NORMAL:
				//原生播放
				system->playSound(sound, 0, false, &channel);
				LOGI("%s","fix normal");
				break;
			case MODE_LUOLI:
				//萝莉
				//DSP digital signal process
				//dsp -> 音效 创建fmod中预定义好的音效
				//FMOD_DSP_TYPE_PITCHSHIFT dsp，提升或者降低音调用的一种音效
				system->createDSPByType(FMOD_DSP_TYPE_PITCHSHIFT,&dsp);
				//设置音调的参数
				dsp->setParameterFloat(FMOD_DSP_PITCHSHIFT_PITCH,2.5);

				system->playSound(sound, 0, false, &channel);
				//添加到channel
				channel->addDSP(0,dsp);
				LOGI("%s","fix luoli");
				break;

			case MODE_JINGSONG:
				//惊悚
				system->createDSPByType(FMOD_DSP_TYPE_TREMOLO,&dsp);
				dsp->setParameterFloat(FMOD_DSP_TREMOLO_SKEW, 0.5);
				system->playSound(sound, 0, false, &channel);
				channel->addDSP(0,dsp);

				break;
			case MODE_DASHU:
				//大叔
				system->createDSPByType(FMOD_DSP_TYPE_PITCHSHIFT,&dsp);
				dsp->setParameterFloat(FMOD_DSP_PITCHSHIFT_PITCH,0.8);

				system->playSound(sound, 0, false, &channel);
				//添加到channel
				channel->addDSP(0,dsp);
				LOGI("%s","fix dashu");
				break;
			case MODE_GAOGUAI:
				//搞怪
				//提高说话的速度
				system->playSound(sound, 0, false, &channel);
				channel->getFrequency(&frequency);
				frequency = frequency * 1.6;
				channel->setFrequency(frequency);
				LOGI("%s","fix gaoguai");
				break;
			case MODE_KONGLING:
				//空灵
				system->createDSPByType(FMOD_DSP_TYPE_ECHO,&dsp);
				dsp->setParameterFloat(FMOD_DSP_ECHO_DELAY,300);
				dsp->setParameterFloat(FMOD_DSP_ECHO_FEEDBACK,20);
				system->playSound(sound, 0, false, &channel);
				channel->addDSP(0,dsp);
				LOGI("%s","fix kongling");
				break;

			default:
				break;
		}
	} catch (...) {
		LOGE("%s","发生异常");
		goto end;
	}
	system->update();

	//释放资源
	//单位是微秒
	//每秒钟判断下是否在播放
	while(playing){
		channel->isPlaying(&playing);
		usleep(1000 * 1000);
	}
	goto end;
end:
	env->ReleaseStringUTFChars(path_jstr,path_cstr);
	sound->release();
	system->close();
	system->release();

}

基本步骤
//初始化 System_Create(&system); system->init(32, FMOD_INIT_NORMAL, NULL);//创建声音 system->createSound(path_cstr, FMOD_DEFAULT, NULL, &sound);//DSP digital signal process //dsp -> 音效创建fmod中预定义好的音效 //FMOD_DSP_TYPE_PITCHSHIFT dsp，提升或者降低音调用的一种音效 system->createDSPByType(FMOD_DSP_TYPE_PITCHSHIFT,&dsp); //设置音调的参数 dsp->setParameterFloat(FMOD_DSP_PITCHSHIFT_PITCH,2.5);//原生播放 system->playSound(sound, 0, false, &channel);system->update();//释放资源 //单位是微秒 //每秒钟判断下是否在播放 while(playing){ channel->isPlaying(&playing); usleep(1000 * 1000); } system->close(); system->release();
4）Android.mk修改为

LOCAL_PATH := $(call my-dir)


include $(CLEAR_VARS)
LOCAL_MODULE := fmod
LOCAL_SRC_FILES := libfmod.so
include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE := fmodL
LOCAL_SRC_FILES := libfmodL.so
include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)

LOCAL_MODULE    := qq_voicer
LOCAL_SRC_FILES := effectfix.cpp
LOCAL_SHARED_LIBRARIES := fmod fmodL
LOCAL_LDLIBS := -llog
LOCAL_CPP_FEATURES := exceptions
include $(BUILD_SHARED_LIBRARY)

5）MainActivity就是更改布局

package org.fmod.example;

import android.app.Activity;
import android.graphics.Typeface;
import android.os.Bundle;
import android.util.TypedValue;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
import android.widget.Button;
import android.widget.LinearLayout;
import android.widget.LinearLayout.LayoutParams;
import android.widget.TextView;

public class MainActivity extends Activity implements OnTouchListener, Runnable
{
	private TextView mTxtScreen;
	private Thread mThread;
	
    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
    	super.onCreate(savedInstanceState);

    	// Create the text area
    	mTxtScreen = new TextView(this);
    	mTxtScreen.setTextSize(TypedValue.COMPLEX_UNIT_SP, 10.0f);
    	mTxtScreen.setTypeface(Typeface.MONOSPACE);

        // Create the buttons
        Button[] buttons = new Button[9];
        for (int i = 0; i < buttons.length; i++)
        {
        	buttons[i] = new Button(this);
        	buttons[i].setText(getButtonLabel(i));
        	buttons[i].setOnTouchListener(this);
        	buttons[i].setId(i);
        }
        
        // Create the button row layouts
        LinearLayout llTopRowButtons = new LinearLayout(this);
        llTopRowButtons.setOrientation(LinearLayout.HORIZONTAL);
        LinearLayout llMiddleRowButtons = new LinearLayout(this);
        llMiddleRowButtons.setOrientation(LinearLayout.HORIZONTAL);
        LinearLayout llBottomRowButtons = new LinearLayout(this);
        llBottomRowButtons.setOrientation(LinearLayout.HORIZONTAL);
        
        // Create the main view layout
        LinearLayout llView = new LinearLayout(this);
        llView.setOrientation(LinearLayout.VERTICAL);       

        // Create layout parameters
        LayoutParams lpLayout = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT, 1.0f);
        
        // Set up the view hierarchy
        llTopRowButtons.addView(buttons[0], lpLayout);
        llTopRowButtons.addView(buttons[6], lpLayout);
        llTopRowButtons.addView(buttons[1], lpLayout);
        llMiddleRowButtons.addView(buttons[4], lpLayout);
        llMiddleRowButtons.addView(buttons[8], lpLayout);
        llMiddleRowButtons.addView(buttons[5], lpLayout);
        llBottomRowButtons.addView(buttons[2], lpLayout);
        llBottomRowButtons.addView(buttons[7], lpLayout);
        llBottomRowButtons.addView(buttons[3], lpLayout);
        llView.addView(mTxtScreen, lpLayout);
        llView.addView(llTopRowButtons);
        llView.addView(llMiddleRowButtons);
        llView.addView(llBottomRowButtons);
        
        setContentView(llView);

        // Request necessary permissions
       /* if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
        {
            String[] perms = { "android.permission.RECORD_AUDIO", "android.permission.WRITE_EXTERNAL_STORAGE" };
            if (checkSelfPermission(perms[0]) == PackageManager.PERMISSION_DENIED ||
                checkSelfPermission(perms[1]) == PackageManager.PERMISSION_DENIED)
            {
                requestPermissions(perms, 200);
            }
        }*/

        org.fmod.FMOD.init(this);
        
        mThread = new Thread(this, "Example Main");
        mThread.start();
        
        setStateCreate();
    }
	
    @Override
    protected void onStart()
    {
    	super.onStart();
    	setStateStart();
    }
    
    @Override
    protected void onStop()
    {
    	setStateStop();
    	super.onStop();
    }
    
    @Override
    protected void onDestroy()
    {
    	setStateDestroy();
    	
    	try
    	{
    		mThread.join();
    	}
    	catch (InterruptedException e) { }
    	
    	org.fmod.FMOD.close();
    	
    	super.onDestroy();
    }
    
	@Override
	public boolean onTouch(View view, MotionEvent motionEvent)
	{
		if (motionEvent.getAction() == MotionEvent.ACTION_DOWN)
		{
			buttonDown(view.getId());	
		}
		else if (motionEvent.getAction() == MotionEvent.ACTION_UP)
		{
			buttonUp(view.getId());	
		}			
	    
		return true;
	}

	@Override
	public void run()
	{
        main();
	}
	
	public void updateScreen(final String text)
	{
		runOnUiThread(new Runnable()
		{
	        @Override
	        public void run()
	        {
	            mTxtScreen.setText(text);
	        }
		});
	}
	
	private native String getButtonLabel(int index);
	private native void buttonDown(int index);
	private native void buttonUp(int index);
	private native void setStateCreate();
	private native void setStateStart();
	private native void setStateStop();
	private native void setStateDestroy();
	private native void main();
	
    static 
    {
    	/*
    	 * To simplify our examples we try to load all possible FMOD
    	 * libraries, the Android.mk will copy in the correct ones
    	 * for each example. For real products you would just load
    	 * 'fmod' and if you use the FMOD Studio tool you would also
    	 * load 'fmodstudio'.
    	 */
    	
    	//System.loadLibrary("stlport_shared");
        System.loadLibrary("qq_voicer");
    }	
}

效果（这个是照着别人后面写的）
