From: Mike Jones on 17 May 2010 18:56 Lets say I have a premastered audio CD called "Side of the Dark Moon", and lets say the first track and second track run together, sounding like continuous music, with no audible silent gap. Lets also say there is no legal problem making a backup copy. cdrdao copy --speed 8 --device /dev/cd2 --source-device /dev/cd1 ....results in a pretty similar copy of a normal music CD, with 2 second gaps between tracks. Ok for general pop music CDs. With the "Side of the Dark Moon" disk, it inserts a 2 second gap between track_1 and track_2, breaking the music continuation. Bah! So, cdrdao read-cd --device /dev/cd1 --datafile cd.bin cd.toc ....gets me a data file and a toc file. cdrdao write --device /dev/cd2 --datafile cd.bin cd.toc ....records a copy, with 2 second gaps between all tracks. Bah! 'man cdrdao' says about the '--fast-toc' flag... "The resulting CD will sound like the source CD. Only the CD player's display will behave slightly different in the transition area between two tracks." ....which sounds like what I need, so, cdrdao read-cd --fast-toc --device /dev/cd1 --datafile cd.bin cd.toc ....and, cdrdao write --device /dev/cd2 --datafile cd.bin cd.toc ....records a copy, with 2 second gaps between all tracks. Bah! I've tried a number of "blindly whacking away at things to see what happens" and "If this works I'm a genius" experiments, but the magic "Do a matching copy without forcing 2 second gaps" end result still eludes me. Does anybody want to show off by pointing out some blindingly obvious solution that I've missed, along with everybody who's written about similar problems in the stuff I've found while searching on this one?

Just kidding... ;-) Seriously though, I once read that some CD writers insert the gaps with silence themselves, ignoring the DAO mode, although this was years ago. OTH, I have used cdparanoia and cdrecord since about 10 years, and they always produced gap-free burns when I told xcdroast to do so.

You don't need to manually fiddle with any value in the toc file. The read-toc command does that for you. I haven't copied music cds in a while, but I used to do it the following way: cdparanoia -d $READ_DEVICE 1- data.wav cdrdao read-toc --device $READ_DEVICE $TOCFILE cdrdao read-cddb $TOCFILE cdrdao write --device $WRITE_DEVICE $TOCFILE I don't know if cdparanoia still exists, you can probably also use cdda2wav or cdrdao for reading data.wav instead.

I haven't copied music cds > in a while, but I used to do it the following way: I think that he starts with one long wave file into which he wants to put track marks so that he can skip to specific sections. But he is finding that when he puts in those track marks something is also inserting 2 sec silence. Since he wants a continuous sound ( ie the sould shuold just flow through the track mark) he does not like it. He is asking how he can insert track marks without also inserting 2 sec of silence. My suspicion is that his .toc file, or his cdrdao commands are telling it to write the cd as a bunch of tracks (TAO mode-- Track at once mode)) rather than in DAO --Disk at once--mode. > > cdparanoia -d $READ_DEVICE 1- data.wav > cdrdao read-toc --device $READ_DEVICE $TOCFILE > cdrdao read-cddb $TOCFILE > cdrdao write --device $WRITE_DEVICE $TOCFILE > > I don't know if cdparanoia still exists, you can > probably also use cdda2wav or cdrdao for reading > data.wav instead. > > Jens > > XP to alt.os.linux

The man page says one thing, then I get gaps anyway. Thanks for assuming I'd not bothered BTW. >> I've tried a few things from the man page for cdrdao, like removing the >> START field's value, removing the START field completely, fiddling with >> various values, but all I get is either a disk with forced gaps, or >> error messages. > > You don't need to manually fiddle with any value in the toc file.

If you have an "I did this and it works" sequence, I'm ready for it. -- *=( http://www.thedailymash.co.uk/ *=( For all your UK news needs. |
