First I fear this question has already been asked but I can't check as the search engine is disabled 
I usually mix with CDR's on my Pioneer CMX-3000 in order not to damage my originals. Sometimes I experienced sound problems : 2 seconds or so without sound in the mix. Yesterday, as I wanted to mix something different, I only played with originals, and didn't experience any problem with the sound.
Anyway I'd like to continue using CDR's. Do you people have some tips to improve sound quality ? Some brand of cdr's you have good results with ? Maybe it's the writer (I'm using a Sony DRU-500A DVD Writer) ? Should I slow down the burning speed (I'm actually burning at 24x, but the speed is not constant, sometimes it's much slower than that).
Please DJ playing with CDR's, give me some help here
Thanks in advance |

Could be a speed-issue. I never burrn audio faster than 4x, and I've never had problems with it. I've experienced that some cd-players won't even read cd's burned at a rater faster than 16x, so your 24x might be a bit risky.

There is a big difference between CDR and CDR.
I have some CDR that is 6-7 yrs old that been in my case going to india several times where the climate is very bad for them that still is fine.
Which is more than I can say about many pressed CD's I have.
Some can't handle a year in sweden even and get scratched extremly easy.
What brand of CD is uninteresting, since the manufacturer can vary from batch to batch in the same brand.
The factory producing the CD is what counts.
Tayio Yuden is considered to be good for audio use, but it can be difficult to know what CD's is made ny them.
CMC is known to be the maker of the lowest quality discs.
I am currently using MPO (sold as hi-space when branded) diamond dye CDR wich seems to be really good. Price on those is double of most CDR though.
The access times is very good when i tried on more sensitive CD players which is a good sign, but only time will tell for sure how well they last.
Gold CD's is in general the best lasting, but again what manufacturer is just as important.
About burn speeds advice used to be that you burn audio at low speed for best results.
That is not entierly true any more.
It depends on the make of CDR and what burner you use.
In general the ones with a blueish green colour (cyanine dye) can be good to burn at lower speeds while the phthalocyanine dye discs should be burned at higher speeds. Around 16x-24x is recommendable for best result.
The best resource for info on CDR is Cdfreaks:
http://club.cdfreaks.com/forumdisplay.php?f=33
If you burn a lot of CD's it can be worth reading thru some posts there.
It's a complicated subject and you need to know quite a bit to be sure what you are getting.

Sinpped from the Cdfreaks FAQ that relates to your question:
Quote:

16) Q: What kind of media will work in my old audio/car player?
A: This is a tough issue, many older players are not designed to read CDR's, and can be very picky about what media they will read. Some people report that using very slow burn speeds will increase compatability, but in fact the type of media you use may be more critical than the burn speed. As a last resort, you can try slow burn speeds, but I suggest keeping it above 16x unless you have some older media that is rated below 16x speed. The most common media that is compatable with older drives is the darker Cyanine-type such as TY (Fuji made in Japan), or Verbatim DataLifePlus. It all depends on the type of laser in that old drive, so if the darker Cyanin-type discs don't work, try the lighter Pthalo-type discs like Ritek. Some audio players will not track anything past 74 min, so be sure to limit your recordings to 74 min. Some players will not accept 80min CDR's, even with only 74 min burned on them. So as another last resort, try some 74min (650MB) discs if you can find them.
17) Q: Is it better to burn at a lower speed?
A: Have a look at THIS thread for some test results. The answer is that it's a question of degrees. Very slow burn speeds are not good when using high speed media in a high speed drive. It's also true that you can almost always improve the quality of your burn by lowering the burn speed a "little bit". For example, my 52x drive can produce very acceptable quality discs at 48x on the right media, but quality improves even more if I burn at 40x. I see very little, if any, improvement in quality by lowering the burn speed to 32x, and decreasing quality below 24x. With older, low-speed rated media you might see better quality at very slow burn speeds, but again the best thing is to try it and test it.

Tayio Yuden CDRs (usually Verbatim Pastel/Colour) can be distinguished by semi-transparent inner circle, and the jars have "Made in Japan" inscription too.. highly r. |

Do you check the CD's for errors in any way after?
Just because you don't get a coaster don't mean that you get the best possible burn.
More errors will apart from reducing sound quality also affect the longlivety of the CD.
If you are using cyanine CD's it's likely that 4-8x is a good speed depending on what burner, but with many new CD's it will be way slow for the CD's to burn well.

well, i use verbatim cdr with an "anti scratch surface" and burn audio cds at 8x.
i tried to scratch them hard with a screwdriver  for test purpose and it was still readable.
i don´t know why i often get unreadable cdr´s from friends, but mine are allways perfect.
oh, i forgot, i bought the best cd-burner (plextor).
maybe this is the reason for my cds allways ruling 
but, does anybody know a freeware program that checks errors (without the original files to compare)? |

Are you burning with TAO (track at once) or DAO (disk at once) ?. if you're using TAO you'll get some silence at the begining of every track (usallly it's 2 sec). Make sure to copy your music with DAO, that will make a clone of the original.
