LameXP is an Audio Encoder Front-End, a graphical user-interface for a number of audio encoders. It was developed to support a huge number of input formats. File formats are detected reliably using MediaInfo. Compressed audio formats are decoded to uncompressed Wave files using suitable CLI audio decoders. Furthermore LameXP allows batch processing of multiple audio files. Multi-threading is implemented by processing several audio files concurrently. All the third-party tools incorporated in LameXP are listed in the "About" dialog. The Nero AAC encoder cannot be redistributed due to licensing issues; it is available as a free download from the public Nero web-site. Note: LameXP does NOT use/need any "external" audio decoders. It neither requires nor supports any ACM Codecs or DirectShow/DMO filters! And it will NOT install anything of that kind on your system.
