Losseless Compression: compress file, decompress file. Compare
original file to decompressed file and you find they're identical.

Lossy: Compress, decompress and compare them and you'll have 2
different files.


Then, according to your definition, CDA is lossy. If you compare th
two
waveforms, you'll have different results. *


MZ, by my definition, it's not lossy. I've done this test. Have you?
Obviously not.

Do yourself a favor. Record something on your PC, or be lazy an
extract a song from a CD, it doesn't matter.

Burn that wav file to a CD.

Extract it from the CD using EAC or CDEX or EZCDDA Extractor (all ar
either free or have free trials of full versions).

Compare the files. They are identical.

The only difference is that there may be extra silence padding th
beginning of the first track and trailing the last track.

The actual sound wave is IDENTICAL. I lined up 4 different extraction
from different software, and they all were identical.

I lwas looking at them down to the millisecond. No difference. It'
Lossless.

You may have a crappy CD drive. You may use lousy softare. Usin
these may mean you get a less than perfect extraction, but you can ge
an identical extraction.

You CANNOT extract a soudn file, compress it with MP3, OGG Vorb, AAC o
WMV and decompress it to the original wave
