This is not a regular burning program, like Feurio and such. Nor is an audio editor. This is really an Audio-CD architect (designer if you want), in the sense that you can control very easily (at least if you are familiar with other Sonic Foundry great line of programs) how to place and work tracks transitions in the CD you want to burn. For burning a regular CD with studio tracks and 2 secs gaps between tracks it doesn't make sense. But it becames specially handy if you want to edit a live recording with perfect transitions, or a dance record for a party with no gaps between tracks and cool transitions.
So, for regular duties use Feurio or whatever you like. For burning a personalized, designer Audio-CD you can use CD Architect. I think it's great for what it does. You can apply effects and other tools on the tracks, but for editing the tracks themselves, the program will better export the tracks to an audio editor, like SoundForge. As said, what the program is meant for is to provide you with a creative tool to design and control the way your final tracks will be burned on the CD, if you want that. If not then just use a regular burning program.
Since I became aware of it I've been playing with CD architect a lot, and have had great fun with it and made some neat compilations.
