I've recorded an awful lot of vinyl and tapes to my hard disk in the APE format, trouble is that they need some work doing on them. I haven't got the time at the moment and I need to free up some disk space so I'm thinking of zipping them up.

Does anyone know of any problems associated with this such as degradation of sound quality etc?

Thanks

well it would seem to me a wast of time to zip them up if you use ape and use high compression when you encode.

you can not compress a already compressed file.

>> degradation of sound quality etc
no

Don't now about APE, but I have restored my whole hard drive from backed up files with no peoblems at all.  Have used both ZIP & Windows XP backup.  All my ripped files sound the same.

As King says, they are already compressed.  No harm to try, but I doubt that you can get much more compression.

Doh!!!!
Ok Ok so it's been a hard day.
Thanks for reminding me of the obvious.

"Zippping" and APE file will often result in Negative compression. While APE files seem huge, because they are lossless, they are highly efficient compression. Zipping can tell about efficiency in format. MP3 can usualy be compressed about 1-2% more. VBR MP3 files usually less than 1/2%
