Easy Microphone Toggler 🎤🔇

A lightweight Windows utility to toggle microphone mute state with a global hotkey or system tray control. Supports multiple audio devices and customizable configuration.

This was made simply because the one in Discord is too bad, and personally sometimes fails me.

Features ✨

• 🔥 Global hotkey (configurable) for instant mute/unmute
• 🖱️ System tray control with visual mute status
• 🎚️ Per-device control (default or specific microphone)
• 🔊 Custom sound effects for mute/unmute actions
• ⚙️ Fully configurable via text file
• 🔄 Runtime reload of configuration
• 🛡️ Low-level keyboard hook option for better compatibility

Installation 📥

1. Download the latest release from [Releases page]
2. Extract the ZIP file
3. Run microphone_toggler.exe
4. Configure mic_config.txt in the same directory

Note: Requires Windows 10/11 (no additional dependencies needed)

Default Hotkey: CTRL + Shift + F1

Configuration ⚙️

The application creates mic_config.txt on first run. Config showcase:

# Use system default microphone device
use_default_device = true

# Specific device name (only used if use_default_device = false)
# Run the program to generate 'available_devices.txt' with available devices
# Copy the exact device name from that file
device_name = 

# Hotkey modifier keys (can be combined by adding values):
#   Alt = 1, Control = 2, Shift = 4, Windows Key = 8
#   Examples: Control+Shift = 6, Alt+Control = 3, Shift only = 4
hotkey_mod = 6

# Main key for hotkey (virtual key codes):
#   Function keys: F1=112, F2=113, F3=114, ..., F12=123
#   Letters: A=65, B=66, C=67, ..., Z=90
#   Numbers: 0=48, 1=49, 2=50, ..., 9=57
#   Other: Space=32, Enter=13, Tab=9
hotkey_vk = 112

# Cooldown for toggling the microphone (0-60000, 0=none, 500=half a second, 1000=second)
toggle_cooldown = 1000

# Use low-level keyboard hook for more reliable hotkey detection
# (May work better in some apps like Visual Studio)
use_keyboard_hook = false

# Play notification sounds when muting/unmuting
play_sounds = true

# Volume for notification sounds (0-100, 0=silent, 100=loudest)
sound_volume = 50

# Sound files (must be WAV format, leave empty to disable specific sounds)
# Files should be in the same folder as this program
mute_sound_file = mute.wav
unmute_sound_file = unmute.wav

# Automatically unmute microphone when program exits
# Set to false if you want to keep the mute state when closing
unmute_on_exit = true

Custom Device Selection 🎤

To use a custom device:
