MAREO is an Open Source (GPL) application that acts as a (M.)ultiple (A.)pplications (R.)unner for (E.)AC and (O.)thers. It was originally developed for use with EAC, but has successfully been tested and adapted to work with CDex. It would probably also work with any other CD ripper.
It works as a (fake) encoder that in turn runs the real encoders for each track ripped by the ripper, passing it the required parameters such as source and destination file, author, CD, track, etc. It can also be used to call other post-compress and pre-compress programs, like ReplayGain. This is is very useful for example, if you like to encode all (or some) of your CDs to Ogg Vorbis for archival, and also to MP3 for use with your MP3 player (when would iRiver support Ogg Vorbis?).
While you can rip an entire CD with EAC (and CDex) to wav, and then run multiple encoders on them, MAREO can do the multiple encodes after each track EAC (and CDex) has been ripped!
It is my (very) humble contribution to the great Hydrogenaudio community, to whom it is dedicated, and also to the EAC (best Free CD Ripper), CDex (best Open Source CD Ripper), foobar2000 (best Free Audio Player), Ogg Vorbis (best Open Source MP3 alternative) and LAME (best MP3 encoder) developers, and to Borland, for Delphi and Kylix, my beloved (and best Windows and Linux) programming environments.
