Developer(s) Stephen Booth
Release information
Initial release {{{released}}}
Stable release 0.8.1
Preview release N/A
Operating system Mac OS X
Additional information
Use Digital Audio Extraction
License GPL


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[edit]

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[edit]

  • Not all output formats are tagged with metadata
  • FLAC cuesheets are not handled on conversion

Development API[edit]

Building Max from source requires the XCode 2.4 tools from Apple, as well as the following packages compiled as frameworks:

  • libparanoia (custom port)
  • cuetools
  • libflac
  • Growl
  • LAME
  • libcddb
  • libmpcdec
  • libogg
  • libsndfile
  • libvorbis or aoTuV
  • MAC
  • mpeg4ip (only the mp4v2 library)
  • TagLib
  • libspeex
  • libwavpack


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.
