Once again -- CDDA is the actual data on the audio CD, and AIFF is just how the computer interprets it. The important thing to note is the bit depth (16 bit) and sampling rate (44.1 kHz) -- and as someone else pointed out in this way-too-drawn-out thread (which is partially my fault), the file has to be stereo (your CD authoring app usually does this conversion on-the-fly when you tell it you want to make an audio CD). The magic happens in Toast (or iTunes, or whatever CD burning software you use) when it converts your computer-based audio file (AIFF for example) to CD audio format on one of those shiny silver discs... - Mark
