感谢

Hi,

how to change the frequency of sound from microphone in windows application c#?

Thanks

推荐答案

我希望Windows应用程序能够从麦克风中获得移频听觉反馈.例如从http://www.artefactsoft.com/daf.htm下载文件
谢谢.

i want windows application that Frequency-shifting Auditory Feedback from microphone. for example file download from http://www.artefactsoft.com/daf.htm
thanks.

原则上，您不能实时修改来自麦克风的声音频率，因为如果违反因果关系原理，就很像以高于速度的速度旅行或发送数据光速.我是认真的.哈哈！ ;)结案.

停止！别着火了，任何人！先想一想.参见下文.

实际上，这全都取决于您所说的更改频率".
如果这是关于实时语音修改的，则可以通过对输入信号进行数字转换以引入非线性失真来实现这些技巧.特别是，可以修改人的声音的可感知音调，但这绝对不同于频率变化.

这是您感兴趣的事情吗? Google之类的东西:

In principle, you cannot modify frequency of the sound from microphone in real time, because if would violate principle of Causality, pretty much like like travel or sending data at the speed above the speed on light. I''m serious. Ha-ha! ;) case closed.

Stop! Don''t start flamе, anyone! Think first. See below.

In reality, it all depends on what you call "change frequency".
If this is about real-time voice modification, such tricks are possible by digitally transforming input signal to introduce non-linear distortions. In particular, perceivable pitch of the human voice can be modified, but this is absolutely not the same as change in frequency.

Is it something you''re interesting in? Google something like this:

("Voice modification" OR "Voice Changer" OR "Pitch Changer") "C#" "Open Source"

如果没有，抱歉:您应该更好地解释您想要什么...

If not, sorry: you should have explained better what do you want...
