SilentBeep
Keep your speakers and headphones awake with inaudible audio pulses.
Keep your speakers and headphones awake with inaudible audio pulses.
Many audio devices go into standby after a short period of silence. When you finally play a sound, you get an annoying delay while the device wakes up — and sometimes you even have to turn it back on. SilentBeep prevents the device from sleeping by periodically emitting ultra-low frequency pulses humans can't hear.
Uses frequencies below human hearing range (10 Hz by default).
Runs in the background with a tiny tray icon and easy controls.
Adjust interval, frequency, duration, audio device and night mode.
Optionally launches with Windows and auto-updates from GitHub Releases.
No telemetry, analytics, or usage data is collected.
