Every now and again a music CD that I burn
is slow, that is ,the music speed is down by probably a full tone consistent for the entire CD. Very strange. I am using quality CD's ( Memorex / Fuji/ Sony) and my burner is a Yamaha 40 X. Generally I burn music CD's at a slow speed , maybe 4x or 8X. And I have 1024 RAM, Operating system 98 SE. Any thoughts other than just a bad CD ? thanks

Tony,You aren't accidentally activating a "pitch" effect, allowing you to offset the pitch, are you? (I'm hoping to be able to do that intentially with some of my audio training tapes that are out of tune by several cents). I've only begun buring CD's recently and I do it a 24X without any problems. My drive and discs are rated at 40X, but my first and only attempt at that speed did not work. ------------------

No Ron, I don't even know if my system has a pitch effect, I've actually never heard of that on a CD but that surely does not mean it does not exist.My CD's generally burn fine but randomly a few pop out with a very slow audio speed..Maybe it's buffer related..Myabe someone can explain it. I've burned many CD's and probably a handful have come out slow. thanks tp |

Hi Tony,
Make certain that no other programs are running in the background when burning the CD's. Anti virus programs are one type of program I can think of right away that can cause problems.
Good Luck,

There is a chance that you are trying to burn audio tracks that have a 48Khz sample rate.

The sampling rate is high, 128 or higher, but I'm note sure why that would matter. CD burn programs convert to .cda regardless of the sampling rate, don't they ? and this is an intermittent problem. Wouldn't a lower sampling rate just end up with lower quality audio ? I can burn maybe 10 CD's with no problem then all of a sudden the next one comes out with slow audio. I did download new firmware from Yamaha today and will reinstall the driver as well . I did see a reference concerning faster audio speed on the Yamaha website which was related to the firmware but nothing relating
to slow audio which points me back to the disks again.still pondering...and throwing away a few disks now and then.. Maybe I'm clicking the mouse button on the "BURN NOW " Icon too slow... to |

I don't understand what you mean by a sampling rate of 128. Commercial CD's are burned at 44KHZ 16 bits. If you are trying to copy a commercial CD then going any higher won't do you any good.Is it always the same CD source that gives you the problem? Make sure that no other programs are running including mail programs that check mail periodically. Don |

More questions...
Are you copying from one CD to another direct? Putting the information that you want to copy on the hard drive first is a better way.
What software are you using to copy? ------------------

Tony--I'm certainly no expert at burning cd's but it sounds to me like Basilh nailed your problem. You probably need to RESAMPLE the files to 44.1 NOT just have the 'exported' or 'read' at that rate. Use CoolEdit or another utility to resample. --Everett |

Ok..The sampling rate that Basilh is referring to I believe is the wave sampling rate or perhaps the MP3 sampling rate , not the CD burning rate. I do burn all CD's at 44.1. Keep in mind this is an intermittent problem, I can burn a dozen with no problem then all of a sudden 1 or 2 come out with slow audio..No changes in configuration.I am going to experiment with the wave conversion altuogh I don't see where that would make any difference other than audio sonic quality, just like MP3 sonic quality. CD burn programs convert whatever to the CD samplng rate of 44.1 , it doesn't care if the music quality is bad.. I will check all my configurations again..maybe something changed and I am not aware of it. thanks to all tp |

Well it's corrected. Basilh was correct . I misunderstood what he was stating and after re-reading it the light bulb went on.
Here's what I had been doing. When recording wave files from my digital recorder I was recording at the highest wave recording format on the PC, 48 KHZ, obviously to get the best audio quality that can be captured. Then in most cases I would convert to an MP3 at CD quality, then burn a CD from the MP3's, all ok.
BUT.. every now and then I would burn direct from the wave files which are sampled at 48KHZ..BINGO. This is where the problem is. Thats a no no.. From this point on I will record all waves at the 44.1 KHZ format sample rate which will burn to CD without any problems and I will be able to mix and match ( MP3's and Waves) in the same burn project. Once again the Forum members come to the forefront with solutions to problems. many thanks guys..this was killing me ! tp[This message was edited by Tony Prior on 28 November 2002 at 06:46 AM.] |

portastudio dealies. BOSS BR8. I really like it, it's easy to use and has some prety nice home grown quality right out of the box.I send the completed track to my PC, which is recorded as a wave file then convert to either CD or MP3. Many of the portastudio dealies have CD burning on board which I suppose would be fine as well but I don't find using the PC a problem at all. The only problem is when you do it wrong, like I was..!! tp |

I currently use the stereo line out of the BOSS BR8 to the PC stereo line in and record at 44.1 khz CD quality. I was at times recording at 48KHZ and that was causing the above mentioned problem. The unit also has an optical digital out for direct to disk CD recorders.tp |
