I dont think its a really big difference. But I know there is a noticable difference.

not a big difference...

but it depends on a lot of things.... how it was burned, what equipment burned it, what brand of cd, waht equipment/install you are listening to it on... etc

NO.

cd's are digital and all burners will write the same thing to the disc unless broken.

then how come burned CDs aren't exactly the same quality as originals?

 

[95mx6gold 10+ year member]

because burned CD's are generally from ripped MP3s. those MP3s are already degraded versions of the song. if you directly made a copy of a CD, the burned copy would be exactly the same.

If you extract the audio files from the original and burn them to a recordable or re-writeable disc as an audio format disc, the quality will be the same. There is no change in the digital information from one disc to the other. If you extract the songs from the original and rip them to MP3s, there will be an audible difference. This quality varies according to the bit level and quality settings you use when converting the original track to MP3.

yeah i guess that makes sense... just seems like a burned copy of a cd wouldnt be 100% same as a store bought original

Not quite. Disc to disc copy will not be as clean as hard drive>cd. Some burners have a wider freq range than others...you might not notice it though...

It's not like making copies of cassette tapes back in the day. Every copy made from a copy degraded more and more. Unlike a tape, there is no mechanical contact to read the sound from the media. The disc simply contains digital data which is read by the laser. If you copy the original format, it is an exact duplicate of the original digital data on the disc. If you rip it to MP3, there is compression and data loss. At this point, you have altered the original file and the sound quality will suffer.

Edit: ^^^^^^ I guess that might be possible as far as reading and playing a disc, but frequency range has nothing to do with digital copy from one disc to another. It is just placing the same pitts of information from the original onto the recording layer of the writeable media.

Jitter during the reading process, jitter during the burning process, coupled with poor media, poor drives, burning too fast, and the natural decrease in the reflectivity of a cd-r compared to a pressed cd can all contribute to loss in quality.

Are these changes great? No.

Can you notice? Only in an A/B comparison. There aren't 'artifacts' such as those that exist in mp3/wma/ogg/etc. compression, it's just a general loss in clarity.

The easiest thing to notice is a decrease in high-frequency output on some media.

Also, i'm not sure if it's still an issue (mainly because i don't read up on it anymore) but when high-speed recorders first became available, there was a big difference in playback quality depending on burn speeds. New high-end recorders have adjustable laser-intensity, as well as 'writing strategies' that allow the laser to work differently according to the burn speed and media being used.

A digital copy is 1:1. Period.

I can take this Windows XP CD, and burn copies from copies of copies of copies, and all day long, I'll have the same Windows XP CD, with the same checksum.

We have error checking, crc, write verification, huge error correcting buffers and failsafes.

If a flaw occured during the copy process, it would be aborted, and you would have a coaster.

A coaster occurs most often because of a buffer underrun.

There is a difference, quite large to me. I have the Jeezy CD burned from 196 kbps MP3s and the original copy is MUCH clearer and not to mention LOUDER than the burned copy.
