超级强大的Android PlayBack和同时录制

我正在使用Superpowered Android C库开发调音台,但在录制时播放器出现问题,播放器未在播放,只有录音器在录制.下面是代码,有人可以指导我在哪里我放错了什么

bool processRecording(short int *input, unsigned int numberOfSamples) {
pthread_mutex_lock(&mutex);
if (askRecording) {
    unsigned int data = 0;

       SuperpoweredShortIntToFloat(input, stereoBufferRecording, numberOfSamples);
       data = recorder->process(stereoBufferRecording, NULL, numberOfSamples);

       playerA->process( musicBuffer, false, numberOfSamples, 0.5f );
       SuperpoweredShortIntToFloat(input, stereoBufferRecording, numberOfSamples);

       SuperpoweredFloatToShortInt(musicBuffer, input, numberOfSamples);

       pthread_mutex_unlock(&mutex);
       return true;
       }
pthread_mutex_unlock(&mutex);
return false;
}

有谁有想法将其放置在正确的位置？

@Gabor建议的更改之后,以下是代码段

bool processRecording(short int *input, unsigned int numberOfSamples) {

pthread_mutex_lock(&mutex);
if (askRecording) {
    unsigned int data = 0;
    SuperpoweredShortIntToFloat(input, stereoBufferRecording, numberOfSamples);

    playerA->process( musicBuffer, false, numberOfSamples, 1.0f );

//=====================================================================================
 // ================== Mixing Two Buffer ==================

    mixerInputs[0] = musicBuffer;
    mixerInputs[1] = stereoBufferRecording;
    mixerInputs[2] = NULL;
    mixerInputs[3] = NULL;

    mixerOutputs[0] = outputBuffer;
    mixerOutputs[1] = NULL;

    float inputLevels[] = { 0.5f, 0.5f, 1.0f, 1.0f, 1.0f, 1.0f, 1.0f, 1.0f };
    float outputLevels[] = { 1.0f, 1.0f };
    __android_log_print(ANDROID_LOG_INFO, "NativeSuperpoweredRecorder  ", " processRecording 2>>");
    mixerBackend->process(mixerInputs, mixerOutputs, inputLevels, outputLevels, NULL, NULL, numberOfSamples);

//=====================================================================================

    data = recorder->process(mixerOutputs[0], NULL, numberOfSamples);
    SuperpoweredFloatToShortInt(musicBuffer, input, numberOfSamples);
    pthread_mutex_unlock(&mutex);
    return true;
}
pthread_mutex_unlock(&mutex);

return false; }

解决方法:

这是您在代码中执行的操作：

输入-> stereoBufferRecording->记录器

输入-> stereoBufferRecording-&gt ;?

播放器-> musicBuffer->输入

当askRecording为false时,播放器根本不播放.

我猜想“输入”和“输出”也是同一个缓冲区？
