Any experience with Resolution Audio Opus 21 CD Player

As a simple analogy, I didn't intend that it be analysed to the depth you are. Just as a quick and ready "a file can be smaller than the original and still have the same data"

images != audio, and as stated ZIP is a general compression algorithm, wheras FLAC and others has been developed only for audio. It really doesn't need that much attention

 

Hi Ian,

You are correct, LZW compression doesn't show any change in the histogram.
Is there a similar instrument one can use to analize a compressed sound file and compare it with an uncompressed one?

Cheers,
Ricardo

 

It does when you are late to the ball...

 

I'm pretty sure that EAC can be used for this sort of analysis.

easiest way to do it - copy a WAV straight from a CD, encode it to FLAC (or whatever other lossless format) decode to WAV and MD5 it to the original file, should be identical (if its not, there's something wrong)

 

Ooops, I don't think I can do that? I'm using a mac and all I have is itunes...

 

you can certainly go down the MD5 route, that's very much cross-platform
