杰克感应C＃ [英] Jack Sensing in C#

问题描述

我正在编写一个能够录制麦克风音频的应用程序。我的问题是我需要知道用户何时插入插孔并拔出插孔。

I am writing an application that will record audio from microphone. My problem is I need to know when the user plug in the jack and remove the jack out.

我查看了 Win32_SoundDevice WMI类，在我看来没有这样的属性我可以查看状态杰克

I looked into Win32_SoundDevice WMI class and seems to me there is no such a property that I can check the status of the Jack.

然后我在 IMMDeviceEnumerator 中找到 RegisterEndpointNotificationCallback 做我需要的但我不知道如何在C＃中做到这一点。有谁知道如何使用 MMDeviceEnumerator 方法来检查音频端口状态？任何帮助高度赞赏。

Then I found RegisterEndpointNotificationCallback in IMMDeviceEnumerator which seems to do what I need but I have no clue how to do this in C#. Does anyone know how to use MMDeviceEnumerator methods to check for audio port status ? Any help highly appreciated.

推荐答案

你可能想看看当时的开源 NAudio 项目。

You might want to take a look at then open source NAudio project.

我浏览了他们的代码，看起来他们有一个.Net包装器您的 IMMDeviceEnumerator 界面。

I've browsed their code and it appears they have a .Net wrapper for your IMMDeviceEnumerator interface.

由于此项目属于Microsoft公共许可证，因此它可能在您的项目中可用。
