C++ 播放音频处理器的最简单的独立JUCE应用程序？

我找到的所有JUCE教程和音频处理器示例都是插件。如果我想创建自己的应用程序，不带插件，播放

音频处理器

，该怎么办

例如：

HelloSamplerAudioProcessor::HelloSamplerAudioProcessor()
     : AudioProcessor (BusesProperties()
               .withOutput("Output", juce::AudioChannelSet::stereo(), true)

我正在将其插入一个

音频设备管理器

，如下所示：

auto samplerProcessor = std::make_shared<HelloSamplerAudioProcessor>();
auto samplerProcessorPlayer = std::make_shared<juce::AudioProcessorPlayer>();
samplerProcessorPlayer->setProcessor (samplerProcessor.get());
deviceManager.addAudioCallback (samplerProcessorPlayer.get());

这些是从这里来的：

void AudioProcessor::setPlayConfigDetails (int newNumIns, int newNumOuts, double newSampleRate, int newBlockSize)
{
    bool success = true;

    if (getTotalNumInputChannels() != newNumIns)
        success &= setChannelLayoutOfBus (true,  0, AudioChannelSet::canonicalChannelSet (newNumIns));

    // failed to find a compatible input configuration
    jassert (success); //line 350

    if (getTotalNumOutputChannels() != newNumOuts)
        success &= setChannelLayoutOfBus (false, 0, AudioChannelSet::canonicalChannelSet (newNumOuts));

    // failed to find a compatible output configuration
    jassert (success); //line 356 

    // if the user is using this method then they do not want any side-buses or aux outputs
    success &= disableNonMainBuses();
    jassert (success);

    // the processor may not support this arrangement at all
    jassert (success && newNumIns == getTotalNumInputChannels() && newNumOuts == getTotalNumOutputChannels());

    setRateAndBufferSizeDetails (newSampleRate, newBlockSize);
    ignoreUnused (success);
}

结果是

AudioDeviceManager

在我的处理器上调用

setPlayConfigDetails

（上面的函数），这会给出断言，因为我的AudioProcessor上没有输入

如果我将输入添加到

HelloSamplerAudioProcessor

，它将不再断言，但我会得到一个回音，即使我禁用了输入。无论如何，我不需要它，我不需要给我的音频处理器添加输入，我只想从它的样本中输出音频

我应该如何在Juce中制作一个只需播放

音频处理器的独立应用程序？
我认为Juce论坛是解决这个问题的最佳场所。另外，作为boiler plate插件项目的一部分，还有一个独立的二进制文件。也许有必要说明为什么这还不够
void AudioProcessor::setPlayConfigDetails (int newNumIns, int newNumOuts, double newSampleRate, int newBlockSize)
{
    bool success = true;

    if (getTotalNumInputChannels() != newNumIns)
        success &= setChannelLayoutOfBus (true,  0, AudioChannelSet::canonicalChannelSet (newNumIns));

    // failed to find a compatible input configuration
    jassert (success); //line 350

    if (getTotalNumOutputChannels() != newNumOuts)
        success &= setChannelLayoutOfBus (false, 0, AudioChannelSet::canonicalChannelSet (newNumOuts));

    // failed to find a compatible output configuration
    jassert (success); //line 356 

    // if the user is using this method then they do not want any side-buses or aux outputs
    success &= disableNonMainBuses();
    jassert (success);

    // the processor may not support this arrangement at all
    jassert (success && newNumIns == getTotalNumInputChannels() && newNumOuts == getTotalNumOutputChannels());

    setRateAndBufferSizeDetails (newSampleRate, newBlockSize);
    ignoreUnused (success);
}
