问题描述
我有一个C＃项目，它将多个（目前为2个）麦克风作为音频设备，检测来自它们的声音，使用傅里叶变换处理它们的音频帧并显示它们。它还以三种颜色打印它们：红色用于具有较强输入的麦克风，绿色用于具有较弱输入的麦克风，灰色用于不足以引起任何兴趣的帧。
我的项目的下一步是计算到达每个麦克风的声音样本的时差。例如，如果我直接对着一个麦克风讲话而另一个距离是3英尺远，那么差异应该是大约3毫秒（假设声速为1英尺/毫秒）。这当然只是一个例子。
任何人都可以帮我这个吗？我已基于此制作了我的项目：
I have a C# project that takes multiple (2 at the moment) microphones as an audio devices, detects sound from them, processes their audio frames with Fourier Transform and displays them. It also prints them in three colors: red is for microphone that has stronger input, green is for microphone that has weaker input and grey is for frames that arent strong enough to be of any interest.
Next step of my project is to calculate the time difference of sound samples that arrive at each microphone. For example if i speak directly to one microphone and the other is 3 feet away, the difference should be about 3 ms (assuming sound speed at 1feet/ms). This is of course just an example.
Can anyone help me with this? I''ve made my project based on this: Sound visualizer in C#
