Audition, how two create bin- and cue-files?

Audition's CD creation has only ever been intended as a quick way of creating client CDs at the end of a session, and isn't really intended for 'production' purposes, as such. And that's why it doesn't have all the same facilities as specialist software does, although it does most stuff like that pretty well. But, unless your friends have Audition, they aren't going to be able to create CD's from the .cdlx file - and anyway, they'd need the original files as well. Either Imgburn, or something like Nero will do what you want though.
