LameXP is a graphical user-interface (front-end) for various of audio encoders: It allows you convert your audio files from one audio format to another one in the most simple way. Despite its name, LameXP is NOT only a front-end for the LAME encoder, but supports a wide range of output formats, including MP3, Ogg Vorbis, AAC/MP4, FLAC, AC-3 and Wave Audio. The number of supported input formats is even bigger! Furthermore LameXP does NOT only run on Windows XP, but also on Windows Vista, Windows 7 and many other operating systems.

As all the encoders and decoders used by LameXP are already "built-in" (with one exception), you do NOT need to install any additional software, such as "Codecs", "Filters" or "Plug-ins", on your computer. Everything works "out of the box"! You can even use LameXP as a "portable" application, e.g. run it from your USB stick. Moreover LameXP was designed for batch processing. This means that you can convert a huge number of audio files, e.g. a complete album or even your entire music collection, in a single step. And, as LameXP is able to process several audio files in parallel, it takes full advantage of modern multi-core processors! However LameXP is NOT only optimized for speed, it also provides excellent sound quality by using the most sophisticated encoders available and by giving the user unrestricted control over all encoding parameters.

In addition to that, LameXP provides full support for metadata, including cover art. So when converting your audio files, LameXP will retain existing meta tags. But there also is an easy-to-use editor for adding or modifying metadata. LameXP supports Unicode for both, meta tags and filenames, so there won?t be any problems with "foreign" characters. And, thanks to our translators, the user-interface of LameXP is available in multiple languages. Last but not least, LameXP supports a number of post-processing filters, including sample rate conversion, normalization (gain), tone adjustment and downmixing of multi-channel sources.
