This project still works fine, but will no longer be worked on; I intend to create a more flexible successor project, but with no particular timeline. When there is more information, I will share it here.

This software:

• makes F15 a global 'mute microphone' hotkey
• makes F16 a global 'unmute microphone' hotkey
• when the microphone is muted, it makes the mouse's first extra/side button a push-to-talk button
• when the microphone is not muted, it makes the mouse's first extra/side button a push-to-mute button
• when PTT is being used, there is a delay of 250ms after releasing the button before the microphone is re-muted. This is because people instincively release the button as soon as they have started prononucing the last syllable, rather than when they have finished

Your keyboard is unlikely to have F15 or F16 buttons; you can likely bind these via your keyboard or mouse customization software, or trigger them via something like an Elgato StreamDeck.

For a more-flexible (but less compatible) solution, consider ahk-micmute.

MicMuteToggle is useful for programs that do not interoperate well with AutoHotKey; for example, Call Of Duty: Black Ops 4 will immediately exit on startup if any AutoHotKey script is running (likely releated to cheat detection).

1. Download from the releases page
2. Run the program; it can be killed from task manager

If you want it to run on startup:

1. hit Win+R
2. type shell:startup and hit enter
3. Create a shortcut to the executable

No end-user configuration is available. The keys, buttons, and delays can be edited by changing the constants at the top of MicMuteToggle.cpp, then rebuilding with Microsoft Visual Studio.
