Question

在为FMOD使用Resonance Audio插件并尝试手动设置DSP而没有FMOD Studio时，我正在努力启用Resonance Audio声音空间化。

我的插件加载和DSP设置代码：

auto system = audio->fmod->system; //instance of FMOD::System
unsigned int resHandle;
CHECK_ERR(system->loadPlugin("../lib/resonanceaudio.dll", &resHandle, 0));

//0 = Resonance Audio Listener
//1 = Resonance Audio Soundfield
//2 = Resonance Audio Source
unsigned int listenerPlugin, sourcePlugin;
system->getNestedPlugin(resHandle, 0, &listenerPlugin);
system->getNestedPlugin(resHandle, 2, &sourcePlugin);

FMOD::DSP* listenerDsp;
CHECK_ERR(system->createDSPByPlugin(listenerPlugin, &listenerDsp));
FMOD::DSP* sourceDsp;
CHECK_ERR(system->createDSPByPlugin(sourcePlugin, &sourceDsp));

//This a channel group routed from the Master group
//I want to spatialize all sounds which are played in this group
FMOD::ChannelGroup *worldGroup = nullptr;
system->createChannelGroup("World", &worldGroup);
FMOD::ChannelGroup *masterGroup = nullptr;
system->getMasterChannelGroup(&masterGroup);
masterGroup->addGroup(worldGroup);

//Adding Resonance Audio dsps to the group
worldGroup->addDsp(0, sourceDsp);
worldGroup->addDsp(1, listenerDsp);

//Setting listener's position at (0, 0, 0)
system->set3DListenerAttributes(0, FMOD_VECTOR{0, 0, 0}, 0, FMOD_VECTOR{0, 0, 1}, FMOD_VECTOR{0, 1, 0});

<loading sound> 

FMOD::Channel* channel = nullptr;
CHECK_ERR(system->playSound(sound, worldGroup, true, &channel));
channel->setMode(FMOD_3D);
channel->set3DAttributes(FMOD_VECTOR{4, 0, 3}, nullptr);
channel->setPaused(false);

<somewhere in update loop>
   system->update();

但毕竟我听不到任何音频。

我认为错误就在我这边，所以我试着在FMOD Studio中重复相同的设置。正如我在代码中所做的那样，我在事件主轨道上的Resonance Audio Listener之前放置了Resonance Audio Source，一切正常（至少在FMOD Studio中，没有在游戏中尝试过）。

如何解决此问题？

我认为你应该致电：

System::getMasterChannelGroup

获取master channel group的实例，然后将Resonance音频DSP分配给主通道组。

//This a channel group routed from the Master group
//I want to spatialize all sounds which are played in this group
FMOD::ChannelGroup *worldGroup>;
<worldGroup setup>

由此我不完全确定你的意思，因为我无法看到你从主通道设置ChannelGroup路由的位置。如果我提供的解决方案不正确，那么请进一步了解我上面提到的代码。

使用FMOD低级API的Resonance Audio时空间化不足
