Deimz

Deimz is a small, open-source publisher whose only public offering, SoundKeeper, addresses a single but perennial Windows frustration: Bluetooth headsets and speakers that power-down when no audio stream is detected, forcing users to reconnect or press hardware buttons to resume playback. Written in portable C++, the utility runs silently in the background and emits an inaudible 20 kHz sine wave every few seconds, just frequently enough to keep the A2DP session alive without consuming measurable battery or bandwidth. Because the signal sits outside most human hearing range and is gated well below the system volume, music, calls and notification chimes remain unaffected, while conferencing apps and media players stay permanently “hot,” eliminating the drop-outs that occur when a dormant device wakes up. The 60 KB executable requires no installer, no elevated rights and no GUI; it can be launched at log-in through a single shortcut and forgotten. Typical beneficiaries include remote workers who live on Teams or Zoom, night-time streamers who pause movies for long stretches, and DJs who need headphones ready for instant cueing. Although Deimz has not published additional titles, the project’s GitHub repository welcomes pull requests and forks, reflecting the developer’s commitment to minimal, single-purpose tools. SoundKeeper is available for free on get.nero.com, where it is delivered through trusted Windows package sources such as winget, always installing the latest build and supporting batch deployment alongside other utilities.
