Great Audio CD Mastering software. Only competitor is Digidesign MasterList, and Jam is FAR cheaper. As best as i can tell, it has all of the features that MasterList professes to sport. Full PQ writing, DAO, large list of supported writers, will spawn an external editor (ships with fully functional Peak LE). It's extremely easy to use, and has yet to make one coaster. Also allows association of mastering info, UPC code, and will output a VERY detailed track list sheet to a text file.
Good Points
Easy UI, DAO & PQ writing (Red Book stnadard), comes with Peak LE Bad Points
A few writers are not supported. May not work with USB, i don't know..
