Kathy, For a change, I don't have a list of questions for you! <g> Re audio recording, some thoughts. When you have a mixed down DAT in hand it _is_ digital audio, but you have to get it onto the disc somehow. I have seen a thread on this board which talked about a pure digital DAT to SCSI transfer product, but there are compatibiltiy problems (he says) and 48 vs 44K problems. If you use a high enough quality sound card (like the Turtle Beach MultiSound mentioned) you can record it in (DAT analog OUT to Multisound analog IN) as a 44K/16bit stereo WAV using something like TB's Wave for Windows. Pay good care to recording levels, etc. A high quality DAT machine will enable you to select the correct 44 or 48K IN. Once you read it in as analog it becomes transparent, and gets recorded at whatever sampling rate you set (eg. 44K) in Wave. Then export the WAV file to raw PCM (a funtion in Wave for Windows), which is, as I understand it, the same as redbook (this merely strips the information header off the WAV file). Then burn the CD. It does involve one more DA conversion, but the problem is that there are no sound cards that I know of with Digital IN. The TB Multisound has very good DA converters, so one round turn is virtually inaudible. Bud

Bud, Thanks for a very clear explanation. However, making a RedBook CD is a little more involved than stripping file headers from WAVE files. There are matters of subcodes, which include information for audio CD players about tracks, timing, etc. This has been one of the sticking points with early premastering software and recorders. Let's keep hammering at this till we figure it out, why don't we? Thanks! Kathy

Kathy, It is my understanding that the more competent premastering software inserts the track and timing info, but you would know more than I. I actually got the header strip trick from the manufacturer's rep for Sony at the PC Expo. He does it all the time and then picks up the file with the Sony premastering software. I have yet to try it, but he says it works. I saw him demo it and it looked pretty straightforward. He set up a master for a combination redbook and data file while I watched. Looked ok to me… The Pinnacle Mac software does it too, but forces you to do separate sessions for the audio and data tracks, leaving the disc unreadable for single session CD readers. Bud

Bud, << software inserts the track and timing info>> It should. Some does, some doesn't. Knowing which is which is part of the fun <weak grin>. The Sony s/w & writer are known to be excellent in just about every regard, and now that the prices are coming down a bit they're likely to be even more ubiquitous. The differences in capabilities of sofware available for the different machines seems to be as important as the quality of the machines themselves. With more and more becoming available it's really a challange to keep up with it all. Kathy
