LameXP is described as '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' and is a Audio Converter in the audio & music category. There are more than 50 alternatives to LameXP for a variety of platforms, including Windows, Mac, Linux, BSD and Web-based apps. The best LameXP alternative is FFmpeg, which is both free and Open Source. Other great apps like LameXP are fre:ac, Freemake Video Converter, StaxRip and Adobe Media Encoder.
With fre:ac I had some problems with the output files, such as duplicate folder names and incorrectly identified characters in file names. LameXP has better support for batch converting audio files in long directorie trees.
