I need to generate an ISO image file for an audio CD that I put together in CD Arch 5.2. Can this be done in CD Arch or Vegas or ...?

Usually, any burning software like Nero, can do this...

Go to Audio CD>import all your songs>Save As>Image File.

It might be a proprietary suffix like .NRG, .IMG , .ISO etc...But any program worth mentioning, SHOULD be able to read these files for burning in the future...

Good luck!!
