OGG claims to be comparable with WMA, MP3 Pro and AAC as a "second-generation" compression technique - that is, higher quality for a smaller file size. I've personally found the lack of support a more practical problem, especially with bandwidth and hard disk sizes increasing. So better than MP3, but not much support. Depends on your set-up whether this matters. I did an OGG installer if that's helpful: lets Windows Media Player play OGG files. http://download.webbie.org.uk/OggCodecsInstaller.msi Best wishes, Alasdair King On Thu, Jan 8, 2009 at 10:34 PM, ANDY COLLINS <Andy@xxxxxxxxxxxxxxxxxxx> wrote: > Hi all - > > What are the main differences between Mp3 and OGG files please; I'm > thinking particularly about file size, and sound quality. > > Thanks - > > Andy -- Alasdair King ** To leave the list, click on the immediately-following link:- ** [mailto:access-uk-request@xxxxxxxxxxxxx?subject=unsubscribe] ** If this link doesn't work then send a message to: ** access-uk-request@xxxxxxxxxxxxx ** and in the Subject line type ** unsubscribe ** For other list commands such as vacation mode, click on the ** immediately-following link:- ** [mailto:access-uk-request@xxxxxxxxxxxxx?subject=faq] ** or send a message, to ** access-uk-request@xxxxxxxxxxxxx with the Subject:- faq
