I agree that the ability to broadcast the output stream from CDA5 to multiple recorders (as in Padus' DiscJuggler) would be wonderful and very useful.

Charlesdem - I wouldn't recommend burning audio at anything over 4x speed if quality is in any way important!

Best wishes,

Burning audio above 4x is bad? What have you seen happen? Thanks.

Eventide:

Although it's not an officially supported feature, you can burn to multiple drives from multiple instances of CD Architect 5.

Yeah Kevin, do you have anything to back this or is this just one of the things "They Say"?

TeeCee: are you talking about burning over 4x for audio CDs? I've experienced these problems often. There isn't any noticeable quality difference between the burning speeds, but any discs burned over 4x won't play in many audio CD players. Anything i've burned at 4x works in any player it's been put in. At 8x about 1/3 of the players we've tried say "no disc" and at 16x about 3/4 of the players reject them. Many of those that do recognize 16x discs play them with lots of skipping.

So, no this is not just something "they" say. It's a very demonstrable fact.

I supply 8x masters to CD manufacturers all the time. While I would agree that 4x is certainly safer, if you use a good blank CD and a good burner (i.e. Mitsui or tayudan media and a plextor burner) you shouldn't have any problems. It's just a matter of how many "errors" show up in testing. There will always be errors on CDRs, but the lower the speed at which you burn, the fewer errors you get. If you're worried about sound quality, if you can play it back, the sound quality is the same whether you burn at 1x or 12 or 16x. (at least, it should be <g>)

Amoungst other things I duplicate CDs for a living. My experience is that with modern media (ie anything 12x or over) burning a 4 x, or moreso 1x or 2x, give a far worse result than higher speeds.

I routinely burn at 8x (similtaneously to 7 burners on one UltraSCSI bus) and get excellent results and no player incompatiblity. I would suggest if you are having trouble at 4x or over you have burner/media incompatibility and should try some experimentation.

I also do compilation for commercially replicated CDs. I have had no plant rejects from production masters I have burned at 8x ( and I did alway use to do 1x until they started giving problems (which was when the 12x media first appeared.

I have been using Mitsui Gold for PM stuff, and SKC (and occasionally 4M and ProDisc - not the best reputations...) for duplication jobs.

PS - It would be really great if CDA5 could write Padus-compatible image files ...;-)

Couldn't cd architect generate ISO cd images files ?
So they could be burned under different softwares.

What Geoff said. You have to realize that your burner or burners is not all burners. The are all different. If I burnt at less than 8x with my Plextor 8/20, I could hear the difference. Demonstrable fact. I had to burn 8x burns with that thing. I mostly use a Plextor 40/12/40 these days, which burns audio at 24x. No compatibility issues, anywhere I've tried it and no audible sound issues. I did a 24x burn in Pyro, extracted the audio on a CD-ROM drive, put the track in Sound Forge, inverted the phase, adjusted the start time, and combined it with the original. The resultant file had no data. I'll continue burning at 24x with that drive.

When people ask me about burning speeds, I tell them to experiment with their burners. I don't give them a one-size-fit-for-me answer. It is good to see that you guys are at least talking from your own experiences.
