What is MicSwitch?
MicSwitch allows you to mute/unmute your system microphone using a predefined system-wide hotkey which will affect any program that uses the microphone (no more heavy breathing during Skype conferences, hooray!). Also, it supports configurable mute/unmute sounds and a configurable overlay with scaling/transparency support. All these features allow you to seamlessly switch between chat apps and use the same input system with overlay and notifications support.
