I made this test:

I took a 24 bit wave file and compressed it in WinZip. I then decompressed it into another folder.

I pulled up my sequencer and loaded the original file in track 1 and the compressed/decompressed file into track 2.

Then I reversed phase on track 2. If both files are identical they will cancel each other out.

Result: They cancelled each other out.


Now, however, WinZip etc. are not good solutions for compression because they don't compress the file much at all and they were not made for that purpose. There is hardly any savings for you to do it this way.

For lossless compression use ape, flac or wavepack. That's right .....get Monkey's Audio.
For lossy compression go with ogg, mp3 or wma.

I perfer ape and ogg.

YMMV
