I have a huge library. I used windows media player to rip most of my cds to my computer. I was wondering if there was another format that would save space, but minimize quality loss? Any suggestions?

what bit rate are you using? is it CBR, ABR or VBR? MP3 or WMA?

WMA

And what bitrate?

128

Watch this space.

This is just a comment: if you ripped and compressed at 128 KBps you are not too much concerned with quality. Also, transcoding will reduce mediocre to pretty bad. Why not add a second drive, or replace what you have with a larger one???

Let's just say there are better choices out there. Have you looked at this audio format guide?

I would re-rip; to just about anything but WMA. And I would re-rip at a higher bitrate than 128Kbps. Your easiest solution, whether you re-rip or not, and the cheapest, if you put a money-value on your time, is to just buy an external firewire or USB hard drive. External drives are less than a buck a gig. Internal drives, less than 50 cents!
