BleepingComputer.com: Compressing Mp3's ?

Is it possible to compress an mp3 file to make room for more songs on a blank audio disc?
If it is possible, how could I do this? I'd appreciate if someone could tell me how

Hi sadieebaby, and welcome to BleepingComputer.

Check out this tutorial, it looks comprehensive.

There are loads of free file converters available. If you can copy the songs (worth doing while you are experimenting with different formats/compression levels) then you can probably find one that allows you to push the compression further without losing sound quality to a really noticeable extent. It really depends how important quality vs storage is to you.

What bitrate are the current mp3s? As has been said, reducing the size of files will reduce their sound quality. I use 192kbps on my CDs, this typically allows me to fit around 9 CD's per disk. If I was so concerned for space or cost of CDs I could reduce that to 128kbps, but for music I would not go below that, nor use 22khz sample rate as per the tutorial. If it is for spoken word (eg electronic book), then using 22khz sample rate, 64k bitrate or mono format could be adequate and would further reduce filesize.

How do I find out how many bitrates the mp3s are?

What are you using to play the mp3s? Most players will show what bitrate the mp3s are - look for something like 128kbps or 192kbps (most common)
