自学体验使用fmod 以及 仿QQ变声 fmod

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:\fmodstudioapi11001android\fmodstudioapi11001android\api\lowlevel 下的inc考入

3.playsound.cpp是主要文件

我们从D:\fmodstudioapi11001android\fmodstudioapi11001android\api\lowlevel\examples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 := fmodLOCAL_SRC_FILES := libfmod.soinclude $(PREBUILT_SHARED_LIBRARY)include $(CLEAR_VARS)LOCAL_MODULE := fmodLLOCAL_SRC_FILES := libfmodL.soinclude $(PREBUILT_SHARED_LIBRARY)include $(CLEAR_VARS)LOCAL_MODULE    := qq_voicerLOCAL_SRC_FILES := play_sound.cpp common.cpp common_platform.cppLOCAL_SHARED_LIBRARIES := fmod fmodLLOCAL_LDLIBS := -lloginclude $(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_staticAPP_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 <jni.h>/* Header for class org_fmod_example_EffectUtils */#ifndef _Included_org_fmod_example_EffectUtils#define _Included_org_fmod_example_EffectUtils#ifdef __cplusplusextern "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 <stdlib.h>#include <unistd.h>#include "org_fmod_example_EffectUtils.h"#include <android/log.h>#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 5using 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channelchannel->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channelchannel->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 := fmodLOCAL_SRC_FILES := libfmod.soinclude $(PREBUILT_SHARED_LIBRARY)include $(CLEAR_VARS)LOCAL_MODULE := fmodLLOCAL_SRC_FILES := libfmodL.soinclude $(PREBUILT_SHARED_LIBRARY)include $(CLEAR_VARS)LOCAL_MODULE    := qq_voicerLOCAL_SRC_FILES := effectfix.cppLOCAL_SHARED_LIBRARIES := fmod fmodLLOCAL_LDLIBS := -llogLOCAL_CPP_FEATURES := exceptionsinclude $(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();    }    @Overridepublic 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;}@Overridepublic 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）
