Simple answer yes.

If you're recording MP3s then the quality will depend on the level of compression not the disk itself.

If you are talking CD Audio (which is NOT the same as a CD with an audio file on it) then if the digital ones and zeros of the original are copied perfectly to the recordable CD then they will be identical in sound quality.

If there are any errors copying or playing the disk then the effects will probably not be subtle. Randomly changing a one to a zero or vice versa usually ends up producing splats and clicks for example.

One thing to note though. A recordable CD is less reflective than a commercially produced CD. So can be more prone to error playing back if the laser on the player is a bit iffy.

Something that I've noticed is that if you are making a CD from your mp3 collection that is playable on a non-mp3 compatible car stereo, they commonly become unplayable after the first few tracks if you select the option to equalise the levels. This isn't really a good idea anyway and it's better simply to adjust the volume during playback.

In general yes, but to minimise the possibility of errors, e.g. skipping, bad batches etc., I'd recommend makes such as Verbatim or Taiyo Yuden, which IMO are the daddies of recordable media.

Basically, don't buy cheap recordable media, whether it be once write or re-recordable. You get what you pay for.

Best way is to burn in flac or wav you can have up to 70 mins I think or longer if in MP3.

If you burn an Audio CD you are limited to 70 or 80 minutes of stereo audio regardless of what format the original audio was in.

If however you burn a Data CD with audio files then you are limited to about 700MB of capacity. mp3 at 128kb/s is about 1MB per minute so you could burn over 700 minutes worth of audio at that bitrate.

128 kb/s .mp3 is rather poor sound quality though, on average.

Personally, I'd go for at least 192, but better 320 (which is near CD quality) for .mp3. However, if you can find a FLAC rendition, then you are quids in.

But why use CD-RW discs at all in the first place? Do you tire of your music that quickly?

CD-RW discs have really poor compatibility with normal audio CD players. Unless the specific player claims support, then it's unlikely they will work.

Cheers,

Strangely enough they tend to work better with cheap CD players more than top of the range machines.

I've never used CD-RW, do they have greater longevity than CD-R because I have a lot of CD-Rs that have become corrupted which, I assume, is age related. They start playing Ok but as they near the last tracks they distort and swish.

CD players have to be specifically designed to accommodate CD-RW's - they are far less reflective than CD-R's and even more less reflective than proper stamped CD's.

Most older players won't even read them, and some even have trouble with CD-R's.

CD-Rewritables are not the best thing for CD-Audio, compatibility is the main reason.

They are also more expensive than CD-R and after you have used one a few times you might struggle to rewrite to one anyway, scratches etc etc.

But assuming the stereo system/CD player can read them then there won't be any difference in audio quality.


This is from memory, nor been using either CDR type for years.

I can't say I've had very many problems with CD-RW compatibility personally, but I do agree they are in general more susceptible to errors, e.g. scratches than CD-R or pre-recorded media for example, which I why I tend to buy music I really like, as far as possible.

Burning more slowly may help and try to avoid over burning, as that can affect compatibility issues. Also buying CDs over 700 Mb capacity (80 mins) can cause problems. 650 Mb (74 mins) was the original standard size IIRC.
