DirectX（DirectSound）应该是WindowXP的一个很好的解决方案。您需要创建一个过滤器（请参阅DirectX的示例，有几个过滤器示例），然后确保使用包含过滤器的图表播放声音。



您的过滤器必须提供有关频率和强度的信息。



一些过滤器示例：

请参阅范围过滤器示例，它是声音的WaveForm表示，接近你想要的。

DirectX (DirectSound) should be a good solution for WindowXP. You need to create a Filter (see the examples of DirectX, there are a couple of filter examples) and then make sure sounds are being played using a graph that includes your filter.

Your filter must then provide information about fequencies and strength.

Some filter examples :

See the 'Scope Filter Example' which is a WaveForm representation of your sound, which comes close to what you want.
