There is a proper way to do it (the same way the "big boys" do it: prepare a DAO track sheet and burn the CD-A in DAO mode), and a hackish way to do it: burn TAO/SAO and set the successive track gap to 0 (actually I'd wager it's one frame, i.e., 1/75th of a second). You can't do this hack for the first track (whose pre-gap cannot be shortened), but thankfully since there's no "prior track" this doesn't matter much. WARNING: not all burners support very small (or zero) values for this pre-gap. Canonical Orange Book spec says 150 frames [2 seconds] between tracks. You can test it properly though: Generate a 60 seconds long audio file of a 4Khz sine wave, split it into two 30 second pieces accurate to 1/75th of a second frame boundary (if possible use a text entry to specify the cut point), or use a command line tool to generate the source files. Burn both files, each as a track with pregap=0, and then capture the playback (via analogue sampling) from your cd player and look for a glitch near the inter-track point. [It should be audible though.] With normal music, depending on the content, the glitch might be masked. If there's a 1/75th "gap" in playback, you'll get a nicely audible phase error. I used to get away with this on my old Yamaha CDR 100 (long may it occupy my shelf of Honoured Dead as a device of Singular Quality)... NOTE! The way "real" audio CDs pull off this caper is to set the PQ bits [welcome to subcode] accordingly to "unmute" the track. When all else looks dark and gray, look to Quality, =MB= -- A focus on Quality.

Hello, I think it was mentioned at the time, but just in case, cdrdao does this very nicely. You'll have to provide it with a TOC file, but these are easy to generate (I use scripts that generate a TOC for a directory of wavs, or based on a m3u playlist, so I can compose the CD with xmms) maarten

Hi, I see a few other folks replied with good answers. Like some of them, I use cdrdao and a script. You probably have a solution so this won't be particularly interesting. Reguardless, I'll post my script. It might be helpful to someone. The script assumes a directory structure '~/clients/'. When run, it searches clients and asks which one to burn a CD for. After making your choice, it searches '~/clients/clientname/master' for *.wav. You are then prompted to specify the amount of time between each track. The format is 00:00:00. A minimum of 00:00:01 seems to be required. The script generates the file cd.toc based on the contents of ~/clientname/master. The script will ask you if you want to use an existing TOC or generate a new one. This script isn't an example of good code. I needed a solution and cobled it together. Incidentally, I also use a script to add clients into '~/clients/'. I require about eight subdirectories for each. That's why the script is designed with a hard coded directory stucture. In my studio data management is not left to the engineers discretion. Everyone of us manages their data exactly the same way. If you add the following function to your .bashrc, then at a command prompt 'client-mastercd'. client-masterCD () { ~/.bin/mastercd } I've got a dozen or so tasks that each engineer must run so having a series of functions named client-whatever in .bashrc helps. -------------------- #!/bin/bash #rtp405(a)yahoo.com #CD-R device lines must be edited for each system. clear ROOT_UID=0 # This script must be run as root.
