我也即将模仿饿了么商家界面，根据饿了么的文章模仿到了一半，卡在Dynamics那里 ，我个人感觉饿了么这一套方案还是比较简单的

Hi Marc,

Thanks for getting in touch. I will perhaps update this for the next version, or maybe with some example code. But for now, here is what I would do at step 4 to fill a buffer with a sine wave... (i've added some extra variables for clarity):

int numChannels = 2;
int numSamplesPerChannel = 100000;
float sampleRate = 44100.f;
float frequency = 440;

for (int i = 0; i < numSamplesPerChannel; i++)
{
        float sample = sinf (2. * M_PI * ((float) i / sampleRate) * frequency) ;
        
        for (int channel = 0; channel < numChannels; channel++)
             buffer[channel][i] = sample * 0.5;
}

I haven't tested this - just wrote it here, but it should work. Hope this helps.

Adam

Thank you so much for your quick response. This worked.

I've now added this to the main documentation in the new version
