winLAME is an encoder for several audio formats, including mp3 (MPEG Layer 3), Ogg Vorbis and more. winLAME lets you set up the encoding process with an easy-to-use wizard-style user interface.

winLAME supports many input audio formats, and uses the LAME mp3 encoding library for encoding and the MAD decoding library for decoding.
