How many mp3 on a cd?

[Kev_UK]

When burning mp3's to cd does it go on time (e.g. 74mins or 80mins max) or filesize (e.g. 650mb or 700mb) ? also should the rewriter be set to data or audio? I thought audio but only around 18 songs would fit on, which I can do as wave files. Windows Media Player was used, so has this converted the mp3 to wave?

It goes on time and not memory- CD's can only store about 80 minutes worth of songs. I dont know what the re-writer should be set to but i would guess audio.

Media player converts the MP3's to wma format

To copy mp3's as mp3's, set your burner to DATA. Setting it to Audio will convert the tracks to the usual CD Audio format. You will only be able to play back the CD on your PC, an mp3 compatable DVD player or an mp3 player which takes CD's. As for amount of tracks - it depends on the size of the songs, but if you take an average of, say 5 mb per song, then a 650mb CD will hold approx. 130 tracks.

If you create a data CD and put mp3s on it the amout will depend on the size of the mp3s: eg you can get 70 10 MB songs on a 700 MB CD. This CD will only play the music on an mp3 reader capable CD player (ie you won't hear the songs if you put it in your hifi CD player). If you create this data CD using files in the uncompressed .wav format you will still only get 700 MB of files on a 700 MB CD and it would still not play in a hifi CD player. However, if you create a music CD, then the software will expand the mp3s and you will get what ever the uncompressed size of the mp3 on the CD: eg if a 10 MB mp3 was actually 100 MB uncompressed you would get 7 mp3s per 700 MB CD. This music CD will play in most CD players (including your hifi). Similarly, if you create a music CD using .wav files you will get aproximately the same number on a 700 MB CD as if you created a data CD (since the .wav files are not compressed). The .wma format is Microsoft's equivalent of mp3s and music CDs created with this files would require the data uncompressing. You can think of the music CD creation as converting compressed files to uncompressed files (like .wav) then converting them to .cda format which hifi CD players can read. Lastly, you should finalise CD-RWs before they are able to be read in standard hifi CDs players.

I usually get anything between 125-150 mp3 tracks onto a CD, depending on track length etc.
