copy's of my store bought cd's dont sound as good. can i improve this by changing software (nero) / Does different media have differing sound quality
How exactly are you copying these CD's? Are you doing a 1 to 1 copy? Are you loading them onto your computer first, then burning them? If your loading them onto your computer first, what are you using to do this? What bitrate are the files on your computer? Answers to these questions will help with answering your question.
i dont think bit rate applies to me does it; I put the store bought music cd in my drive, using nero i have been using the copy button to make copy. is this considered one to one? If I used two drives simultaniosly ;a method i believe called on the fly? would this improve the sound. does the record speed make a difference?
When you do a copy, "on the fly", you are recording onto the CD-R as it is being read from the original. You have to make certain that the read speed is faster than the recording speed. Try unchecking "copy on the fly" & see if that works. What it will do is make an image of the CD on your computer, then burn that image to the CD-R. One other thing that I've seen other people say, & I don't know how much truth there is to it, is to set your write speed to half of what the CD says is it's maximum speed. What brand of CD-R are you using? This may be part of the problem. There are some pretty bad ones out there. I use Maxell, that I buy from Wal-Mart. Never had any problems with them.
For the recored, recording media has nothing to do with quality (because the proccess is digital, Audio CD's contain PCM based files sampled at 44.1 KHz, with 16 Bits of resolution)! Now, thats not saying that there all created equal as digidave pointed out. Ced
