MP3 Encoder is an application for converting a variety of audio formats to MP3 using the high quality LAME encoder. It is multi-threaded and will batch convert multiple files at once, up to the number of processor cores your system has. It supports reading and writing metadata, including album artwork, and can create custom output file paths based on the metadata. It can also edit the metadata of existing MP3 files, functioning as a basic MP3 tag editor.

MP3 encoder provides you with a full range of MP3 encoding options. You can select from all of the encoding methods, bitrates, algorithm qualities, and stereo modes offered by the LAME encoder.
