🔊 SoundKeeper - Bluetooth Audio Device Keep-Alive

SoundKeeper is a lightweight Windows application that prevents Bluetooth audio devices from automatically entering standby mode due to inactivity.

Many Bluetooth audio devices (soundbars, speakers, headphones) automatically disconnect or enter standby mode after ~60 seconds of silence. This is especially common with devices originally designed for TVs or with aggressive power-saving features. SoundKeeper solves this problem by playing imperceptible audio signals at regular intervals, keeping your device active and connected without any audible sound.

• 🔇 Imperceptible Audio - Plays white noise at extremely low volume (completely inaudible)
• ⏱️ Smart Timing - Sends keep-alive signals every 55 seconds (before typical 60s timeout)
• 🎯 System Tray Integration - Minimalist interface accessible from the taskbar
• ✅ Easy Toggle - Enable/disable with a single click
• 🚀 Startup Option - Configure to launch automatically with Windows
• 🛡️ Single Instance - Prevents multiple instances from running simultaneously
• 🪶 Lightweight - Minimal resource usage (~25MB RAM)

No Python or programming knowledge required!

1. Go to the Releases page
2. Download SoundKeeper.exe from the latest release
3. Double-click the executable - no installation needed!
4. A green Bluetooth icon will appear in your system tray
5. Optional: Right-click the icon and enable "Launch at Startup" to run automatically

That's it! Your Bluetooth device will now stay connected.

Requirements:

• Python 3.7 or higher
• Windows OS

Installation Steps:

# Clone the repository
git clone https://github.com/Deimz/SoundKeeper.git
cd SoundKeeper

# Create virtual environment
python -m venv venv
.\venv\Scripts\Activate.ps1

# Install dependencies
pip install -r requirements.txt

# Run the application
python soundkeeper.py

1. Launch SoundKeeper - Double-click SoundKeeper.exe
2. Look for the icon - A green Bluetooth icon appears in your system tray
3. It's working! - Your audio device will now stay connected

Right-click the icon to access:

• ✅ Active (Keep-Alive) - Toggle the keep-alive feature on/off
  • 🟢 Green icon = Active
  • ⚫ Grey icon = Paused
• 🚀 Launch at Startup - Register/unregister from Windows startup
• ❌ Quit - Exit the application

SoundKeeper works with any Bluetooth audio device that has auto-standby/timeout features:

• ✅ Soundbars (Samsung, LG, Sony, etc.) - Especially TV soundbars used with PCs
• ✅ Bluetooth Speakers - Portable or desktop speakers with power-saving modes
• ✅ Wireless Headphones - Any brand with aggressive auto-sleep features
• ✅ Home Theater Systems - Bluetooth-enabled receivers and amplifiers
• ✅ Smart Speakers - When used in Bluetooth mode

Advanced users can modify settings in soundkeeper.py:

SAMPLE_RATE = 44100    # Audio sample rate in Hz
DURATION = 1.0         # Keep-alive sound duration (seconds)
INTERVAL = 55          # Interval between signals (seconds)
AMPLITUDE = 0.0001     # Sound volume (very low = imperceptible)

To create your own executable:

# Install PyInstaller
pip install pyinstaller

# Build the executable
pyinstaller --onefile --windowed --icon=icon.ico --name SoundKeeper soundkeeper.py

# Find your .exe in the dist/ folder

• Make sure SoundKeeper is running (check system tray)
• Verify the feature is enabled (icon should be green)
• Try reducing INTERVAL to 45 seconds in the configuration

• Only one instance can run at a time
• Check the system tray for an existing icon
• Close it before launching again

• Check Windows notification area settings
• Make sure the application hasn't crashed (check Task Manager)

• OS: Windows 10/11 (64-bit)
• RAM: ~25MB
• Storage: ~30MB
• Audio: Any audio output device
