How to mute the microphone c#

c# keypress microphone mute
Sean picture Sean · Jan 16, 2010 · Viewed 10.7k times · Source

I wanted to know, what would the coding be if I wanted to toggle mute/unmute of my microphone. I am making a program that can run in the background and pickup a keypress event and toggle mute/unmute of the mic. Any help with any of that coding would be very helpful. I am pretty new to C#, and this is just a really simple program I wanted to make. That is all it does, is it will listen for keypress of the spacebar, even when the program is in the background, then when the spacebar is pressed it will mute/unmute the mic.

Thank you for any and all help!

For Windows Vista and newer, you can no longer use the Media Control Interface, Microsoft has a new Core Audio API that you must access to interface with audio hardware in these newer operating systems.

Ray Molenkamp wrote a nice managed wrapper for interfacing with the Core Audio API here: Vista Core Audio API Master Volume Control

Since I needed to be able to mute the microphone from XP, Vista and Windows 7 I wrote a little Windows Microphone Mute Library which uses Ray's library on the newer operating systems and parts of Gustavo Franco's MixerNative library for Windows XP and older.
