A recent discussion brought a question to mind: How much effect does zipping and unzipping an ogg file have on the original form? -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.xiph.org/pipermail/vorbis/attachments/20060209/2e81e6fe/attachment.html

Zipping and unzipping is lossless compression. Decompressing a zipped ogg will give you exactly the same ogg. Usually there is no point in compressing an ogg/mp3/jpeg, as they have little redundancy and the compression ratios are very low. You'll end up only wasting processor time in applying the compression algorithm. Hugo
Thank you all very much for dealing with my question and satisfying my curiosity. ----- Original Message ----- From: Paul [mailto:public@ellisfoundation.com] Sent: 2/10/2006 1:17:07 AM To: hugonz-lists@h-lab.net Cc: srussell@innernet.net;Vorbis@xiph.org Subject: Re: [Vorbis] zipping an ogg file> Just for curiosity I zipped up an Vorbis file to look at the extra > compression I attained.
