Well, after all that posts above, you'll have to be thankful that Microsoft coded that 'crap', because without which you can't play Audio CD's easily from within Windows. Just re-stressing the point: No, your Audio CD does not have WAV files in them. Just a 'raw PCM-encoded datastream'. In fact, Windows have to go head over heels, jumping through several hoops just to provide users a direct (i.e. from WinExplorer) access to an Audio CD.Let's see: A 'Red Book' Audio CD has no filesystem. It only has a 'TOC' pointing *roughly* where each track starts. Somehow Windows Explorer slaps on a pseudo-filesystem on top of this TOC. When you doubleclick on a .cda file, Windows will read the TOC's pointer, and do some low-level acrobatics to have the CD drive to just start reading the pointed-at sector. Then Windows' driver will then redirect the 'raw' data being read from the CD to the sound driver to make audible sound. Now, a CD Ripper does exactly the same, except that instead of redirecting the 'raw' data, it captures the data onto hard disk, properly packaging/encapsulating it within a 'container file', which most commonly in Windows is 'WAV'. The 'WAV' container provides additional data like bitrate, bits per samples, number of channels, etc. which are not available in the raw data (except intrinsically, i.e. 'Red Book' Audio CD is 44'100 samples per seconds, 2 channels per samples, 16 bits per channel-sample).
