Adobe Audition v1.0 was exactly the same as CoolEdit Pro v2.1a (other than a few minor additions, such as hooks into some of Adobe's other software). For most users, there was absolutely no difference between these two applications, other than a change of name. Adobe have now released AA v1.5 and this does have some new toys to play with and could certainly be considered an improvement over the old CEP. The main drawback is that it does not understand ASIO - you have to use WDM drivers or something similar - and, for users of this forum, it's midi capabilities are virtually zero (you can play a midi file, but not edit it or record a new one) although it is possible to sync lock it to a midi sequencer. It's still a very fine audio editor and has a lot of useful tricks for those in the restoration game (again, not for most here, of course).
