C＃中的拍手声音检测

[英]Clap sound detection in C#

原文 2009-06-11 11:51:10 4 5 c#/ audio/ sound-recognition

I would like to be able to detect a clapping sound. 我希望能够发现鼓掌声。 Being pretty new to any form of sound recognition, is there simple any way to do this? 对于任何形式的声音识别都是新手，有什么简单的方法可以做到这一点吗？ If not, any good resources for C# sound recognition/detection? 如果没有，C＃声音识别/检测的任何好资源？

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端媒体中心。

There was a similar question asked in the past: 过去有一个类似的问题：

Given an audio stream, find when a door slams (sound pressure level calculation?) 给定一个音频流，找到一个门猛击（声压级计算？）

Although the question was not specific to C#, it does have some ideas for algorithms to use. 虽然这个问题并不是针对C＃的，但它确实有一些算法可供使用。 (Disclosure: Yes, I did answer that question.) （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 . 不确定这是否会有任何帮助，但仍然是： MERL - 声音识别。 Or better yet, Clap detection, with microphone . 或者更好的是，拍手检测，带麦克风。

I wouldnt focus on the language as such, but on the algorithm. 我不会专注于这种语言，而是关注算法。

What characteristics of a sound allow you to identify it as a clap? 声音的哪些特性允许您将其识别为拍手？ Duration? 时间？ Intensity? 强度？ Variation of intensity over time? 强度随时间的变化？

Once you've got an algorithm, then decide the best way to implement it. 一旦你有了算法，然后决定实现它的最佳方法。

查看音频区域触发器只需25美元，看起来它会完全符合您的要求。

It seems like a problem you can solve using a so called Principal Component Analysis. 这似乎是一个问题，您可以使用所谓的主成分分析来解决。 Try to google it. 试着谷歌吧。 Also other solutions for the famous Cocktail Party Problem may help. 其他着名鸡尾酒会问题的解决方案也许有所帮助。 But I am sure there are already some libraries out there. 但我相信已经有一些图书馆了。
