About:
Mpg321 is a lightweight, command-line MP3 player that serves as a free and open-source alternative to mpg123. It decodes and plays MP3 audio files directly from the terminal or within scripts, making it ideal for headless systems and embedded environments.
Key Features:
  • Lightweight and fast decoding of MP3 files
  • Supports streaming from HTTP and network sources
  • Provides a control interface for remote operation
  • Minimal dependencies and low resource usage
Use Cases:
  • Playing audio on headless servers without a GUI
  • Scripting audio playback for automation or announcements
  • Running on embedded systems or devices with limited resources
Alternatives:
  • mpg123 – The original project; mpg321 was created as a free software alternative.
  • sox – A general-purpose audio toolkit that can play files but is not a dedicated MP3 player.
