Clap sound detection in C#
提问by jamesrom
I would like to be able to detect a clapping sound. Being pretty new to any form of sound recognition, is there simple any way to do this? If not, any good resources for C# sound recognition/detection?
我希望能够检测到拍手声。对任何形式的声音识别都很陌生，有没有简单的方法可以做到这一点？如果没有，C# 声音识别/检测有什么好的资源吗？
My goal is to automate a clients media center with some basic clap-based controls.
我的目标是使用一些基于拍手的基本控件来自动化客户媒体中心。

There was a similar question asked in the past:
之前有人问过类似的问题：
Given an audio stream, find when a door slams (sound pressure level calculation?)
Although the question was not specific to C#, it does have some ideas for algorithms to use. (Disclosure: Yes, I did answer that question.)
虽然这个问题不是特定于 C# 的，但它确实有一些算法可以使用的想法。（披露：是的，我确实回答了这个问题。）

Not sure whether this will be of any help, but still: MERL - Sound Recognition. Or better yet, Clap detection, with microphone.
不确定这是否有任何帮助，但仍然：MERL - Sound Recognition。或者更好的是，使用麦克风进行拍手检测。

It seems like a problem you can solve using a so called Principal Component Analysis. Try to google it. Also other solutions for the famous Cocktail Party Problem may help. But I am sure there are already some libraries out there.
这似乎是一个可以使用所谓的主成分分析来解决的问题。尝试谷歌它。著名的鸡尾酒会问题的其他解决方案也可能有所帮助。但我相信已经有一些图书馆了。

I wouldnt focus on the language as such, but on the algorithm.
我不会专注于语言本身，而是专注于算法。
What characteristics of a sound allow you to identify it as a clap? Duration? Intensity? Variation of intensity over time?
声音的哪些特征可以让您将其识别为拍手？期间？强度？强度随时间变化？
Once you've got an algorithm, thendecide the best way to implement it.
一旦你有了一个算法，然后决定实现它的最佳方式。
