How many CD-R data can an MP3 CD carry?

[coody]

I wonder whether I can copy several regular CD-R audio CDs into one MP3 CD. A regular CD-R can store 700MB data. The MP3 CD may store more data than a regular CD-R does. Is it correct? If so, can I convert and copy several regular CD-R into one MP3 CD? Thank you for your answer.

You might try CDex. How many files depends on the size they end up being as MP3s.

You are confused.

700mb of MP3's on a CD is just that 700Mb of data.
How many MP3 you can store on one 700Mb CD is proportional to the compression. The higher the compression the more MP3 you can store.
Depending on bitrate (128)(and of course the lengths of the songs) i'd expect you'd fit ~150 songs. Less of course for higher bitrates.

I would like to convert and directly copy several audio CD-Rs into one MP3 CD disc. Do you know whether the Roxio RecordingNow Music Lab 9 can directly burn an MP3 disc from the audio CD-R disc (disc to disc)? If yes, would you tell how to do it? If no, what software can do it? Thanks.

Can't be done,you need to convert to MP3 first then make a data CD.
As was mentioned above use CDex to convert.

If you want to copy several CDs and have the best chance of it playing back then rip and convert them to your HDD, and when you have enough files to fill a CD, burn the files, as data, in a single session. If you try to rip and burn them one CD at a time then the resulting CD will be multi-session and won't lay in many players.

As was pointed out previously, CDex is a great tool for ripping and converting.

Does anyone know how many MB or GB data, or minutes one MP3 CD can hold?

[loster]

Running Time varies depending on the bitrate. The smount of space is constant for the media 700 MB of data.

Roughly 10-12 Audio CDs can be squeezed onto a MP3 CD. Very roughly, but there are so many unknown parameters involved, you wont get a more accurate estimate.

74 minute CD-Rs (does anyone still make these?) can hold 650 MB of data.

80 minute CD-Rs can hold 700 MB of data.

As to how many songs you can get on a CD-R, it depends on the bit rate of your MP3 files.
Higher bitrate = higher quality = fewer songs
Lower bitrate = lower quality = more songs

You can have more of quality or quantity (number of songs), but not both. I would not advise using bit rates for MP3 below 128. Some people feel very strongly that you need to use 192 or above. You'll need to be the judge of what works for you, but I can tell you that just about anyone can hear artifacts at bit rates below 128 and many people can tell a difference between the MP3 file and the original song at bit rates less than 192 with that difference being that the MP3 file doesn't sound as good as the original. Several studies have shown that most people can't tell a difference between the original and the MP3 file at a bit rate of 192. My brother, who has pretty good hearing and a good amount of musical ability, thinks that 128 is good enough for what he listens to. Then again, I worked with a guy once who was adamant that any MP3 made at a bit rate below 224 was garbage. You need to be your own judge for what works for you.

It's not just the bitrate that determines the quality. There are other settings in an MP3 encoder that have a dramatic effect on sound quality. To my ears joint stereo sounds awful, especially on recordings with greater stereo width. I've also found that VBR sounds better than CBR for the same average bitrate. This is because it allows the encoder to use a higher bitrate when needed. The difference is most noticeable on cymbals. They contain a large amount of white noise which is very difficult to compress without obvious artifacts. I settled on 192kbps normal stereo VBR.

As noted here on many occasions, VBR MP3s should not be used in conjunction with video files. Apparently it causes timing problems. There's nothing wrong with using it for CD rips though.

Except sometimes it's also bad for software players that'll give the wrong time or hardware players that end up with glitches.

I avoid VBR audio like the plague, unless completely necessary.
