LAME MP3 Encoder 32bit is an open-source audio encoder for Windows PC. The encoder is not a graphical application that you can double-click, but a command-line tool, usable from the Terminal application (which lives in the utility folder inside the Applications folder) or other graphical applications.

Features and Highlights
  • Many improvements in quality in speed over ISO reference software. See history.
  • MPEG1,2 and 2.5 layers III encoding.
  • CBR (constant bitrate) and two types of variable bitrate, VBR and ABR.
  • The encoding engine can be compiled as a shared library (Linux/UNIX), DLL, Directshow filter, or ACM codec (Windows).
  • Free-format encoding and decoding.
  • GPSYCHO: a GPL'd psycho acoustic and noise shaping model.
  • Powerful and easy to use presets.
  • Quality better than all other encoders at most bitrates.
  • Fast! Encodes faster than real-time on a PII 266 at the highest quality mode.
  • MP3x: a GTK/X-Window MP3 frame analyzer for both .mp3 and unencoded audio files.
System Requirements

LAME MP3 Encoder is designed to be lightweight and can run on a variety of operating systems, including Windows, macOS, Linux, and Unix-like systems. It has minimal system requirements and should work well on most modern computers.

  • Outstanding audio quality.
  • Open-source and free to use.
  • Cross-platform compatibility.
  • Advanced users can fine-tune encoding settings.
  • Efficient batch processing capabilities.
  • Command-line interface may be intimidating for beginners.
  • Lack of a built-in graphical user interface (GUI).
