MicKey is a portable Open Source app that allows you to toggle your machine's microphone using a simple hotkey.
An app such as this will be of great use for those recording or talking via video conference. We all know that interruptions happen, so having a fast and efficient option to turn the mic on/off is a great asset. The UI is barebones and allows you to toggle on/off and set your preferred hotkey. The interface is also color-coded, so you know immediately if the mic is hot. Green is for on, and red is off - no more guessing. When in use, it will always be left on top or dropped down to the systray. When down in the systray, the icon will change colors and provide a visual cue if the mic is on or not.
MicKey is a simple tool to turn your mic on and off through a hotkey that will give a visual of what state your mic is in.
