About This Tool

This tool helps you generate blank audio files in four different formats (mp3, wav, m4a, ogg), with the ability to specify any length. The generated blank audio files are truly silent, containing no sound or noise whatsoever.

Where Are Blank Audio Files Useful?

  • For organizing playlists. Blank audio files of specific lengths can be used for timing or as silent timers, allowing you to schedule music or advertisements to play after a waiting period.
  • For software and game development. In some scenarios, blank audio files can be used as placeholders.
  • As a background keep-alive mechanism for apps. In iOS applications, playing silent audio allows apps to continue running in the background, preventing the system from suspending them—a common technique for keeping apps active.

Blank audio files are essentially valid audio files containing “zero amplitude” sample data, rather than simply being in a “no file” state, making them essential in various technical and creative applications.
