From Hydrogenaudio Knowledgebase
Max is a digital audio extraction algorithm that allows for secure rips under the Mac OS/X platform. It uses its own built-in comparison ripper, along with error correcting power of cdparanoia. Max is released under the GPL license.
- Supports over 20 different audio codecs (AAC, MP3, Ogg Vorbis, FLAC, WavPack, etc)
- Integration with FreeDB permit automatic retrieval of compact disc information
- Queing files for output to ITunes.
- Threading control for encoding/decoding
- Custom port of cdparanoia
- Works in conjunction with Cog and Tag
 Correction mechanism
Max correction mechanism is quite similiar to Rubyripper. The algorithm uses a comparison feature in order to determine how many times Max should rip and compare sections (maximum retries). It is done on a sector-by-sector basis, rather then byte-by-byte basis. Max can additionally generate a SHA-256 checksum for each additional section in order to more accuratly determine dissimiliarities in a rip. Max differs in that it does not have a direct reliance on cdparanoia for extraction, but instead uses C2 error pointers very similiar to EAC.

 Known Bugs
- Not all output formats are tagged with metadata
- FLAC cuesheets are not handled on conversion
 Development API
Building Max from source requires the XCode 2.4 tools from Apple, as well as the following packages compiled as frameworks:
libparanoia (custom port)
libvorbis or aoTuV
mpeg4ip (only the mp4v2 library)
If you would rather not compile all these from source, you may download precompiled versions of the frameworks (2.36 MB). Unzip this archive into Max's source directory.
