This is a fairly complete high-level Haskell binding to LAME.

Provided functionality

  • Fast MP3 encoder working in various modes (you specify compression ratio, desired bit-rate, or parameters for VBR), with quite a few interesting options to tweak.
  • Setting of all common tags, including pictures.


  • No decoding for now. It’s actually done via a separate library in LAME.
  • Relatively limited (compared to ID3 specs) number of tag fields available for setting.
  • Some sample widths are not supported: less than or equal to 8 bit and greater than 16 bits (for integer samples, floats work OK).
  • Some psycho-acoustic and noise-shaping settings are not available for tweaking.

Open an issue if something of this is a deal breaker for you, some of these limitations are easily lifted.


Please kindly direct all issues, bugs, and questions to the GitHub issue tracker for this project.
