1. What is EarPurifier?

EarPurifier (Arabic: هدوء) is a free, privacy-first desktop application designed to remove background music from videos and audio recordings (such as documentaries, lectures, educational materials, and podcasts) using state-of-the-art AI models.

The Big Picture of How It Works:

  • You have a video or audio file containing speech overlapping with background music.
  • EarPurifier extracts the audio track cleanly without altering your original file.
  • Advanced AI neural networks isolate vocals and strip background instruments with surgical accuracy.
  • The application instantly re-assembles your media file, guaranteeing:
    • 100% Original Video Quality: The video stream is preserved untouched.
    • Embedded Subtitles: All subtitle tracks and chapters remain completely intact.
    • Perfect Lip-Sync: Digital alignment ensures voice and picture remain synchronized down to the millisecond.

Two Processing Modes in EarPurifier

EarPurifier provides two distinct processing engines — choose the one that best suits your computer:

  • ☁️ Cloud Engine (Cloud Mode via free Kaggle T4 GPUs):
    The recommended choice for most users. Offloads heavy AI processing to remote cloud GPUs for free, enabling you to run top-tier models at blazing speeds without taxing your local PC or needing a high-end graphics card.
  • 💻 Local Engine (Local Mode — 100% Offline):
    Executes AI models directly on your device via your graphics card or processor. Operates completely offline without requiring any internet connection after a simple one-click initial setup.
