Are you talking of pre-gaps here? They are not prescribed. Bear with me if I'm a little to verbose, and let me ramble on a little more: When you burn in TAO-mode, the burner _itself_ adds two seconds gaps between the blurbs it has to burn, as prescribed by the standard. But there are some burners that allow you to specify the length of this automatically added gap, and some of those even allow for a zero lengthed gap. The blurbs written in TAO may all be composed of several wav-files. For each blurb all the wav-files it contains are concatenated and burned as if it were one big wav-file. DAO is quit a different beast. It writes only one big blurb to disc. If you specify to write several wav-files (audio-tracks) then all of those wav-files are simply concatenated and burned to disc as if it where one big wav-file. So actually DAO resembles TAO for one track. And for both modes the TOC (generated by the burning software) tells were the audio-tracks are located on disc. In DAO it's quit costumary to have several TOC entries pointing into the one blurb written, but nothing stops you from doing the same in TAO (if the software allows it, that is.) In the end it's up to the burning software what gets written into the TOC; it specifies the automatically generated gaps in TAO mode as pre-gaps, but there is no need to specify pre-gaps otherwise. But then, there are some old players, who misinterpreted the standard and (try to) add silence gaps in between all TOC entries:( All the above is as I recall to have read somewhere, so... ... > You may be saying the same thing. maybe, but I'm in a verbose mode today, so I rambled on:) ... > Fair enough.

Ah, second level indexes, not many a player can cope with those. > BTW when splitting wav files, Jake, it's important to make sure they're > broken at 2352-byte boundaries so you don't get gaps between them. Good Advice, as some burners choke on inappropriate sized blurbs! -- groetjes, carel
