Audio file length versus size

Recommended Posts

I burned a CD-R using the build function. There were about 12 MP3 audio files, each one about 50 minutes long. The total size of the files was about 550 Mb. So I am confused since the Verbatim CD-R is an 80 minute CD. How is it possible to put about 10 hours of MP3 audio on an 80 minute CD?

 

Sorry if this is a stupid question....

Probably because you built a Data CD and not an Audio CD.  Unless you used the Create CUE function, you didn't create an Audio CD but a Data CD.  Data CD doesn't care how long the MP3's file are as long as the file sizes don't exceed the side of a CD.  And 12 MP3's at 50 minutes each probably don't exceed 750 MB, the amount of data on a CD.  As you said, the resulting creation was about 550 MB, which would fit on a CD.  You said you used the "build" function, which would create a Data CD.

 

 

As you say, if you built an Audio CD, there would be no way to put all 12 50 minute tracks on one Audio CD.  In fact, you could only fit 1 track per CD if you created an Audio CD.
