Analysing .WAV files

Ok folks one for the more technically minded bods. Does anyone know of a piece of software that I could use to analyse two .wav files to determine the differences between them. The reason I'm asking is to determine whether a lossless copy of a track I have came from an original source or is from a CDR of an MP3. Basically my logic is that if I convert the MP3 to a .wav and then compare this to the decompressed lossless file if they are identical then the lossless file was generated from an MP3 and so is no better than the MP3 (if that makes any sense). Any advice, hints etc. would be appreciated.

i have no idea what you are trying to do.. but if you just wish to analyse wav audio frequency wave forms then get something like Sony Soundforge or Acid Pro...

 

Cool Edit Pro would be my guess...
www.syntrillium.com

 

cool edit is now owned by Adobe
and SoundForge / Acid by Sony...
Sony also do SoundForge XP which is very handy and will pretty much allow you to have a good look at those waveforms for about $60USD. Useful recording and editing tool, too.

 

I would have thought that simply listening to it would be a good enough test.

I ran some side by side tests with a friend a couple of years back of MP3 vs CD WAV, both using the PC as source. Even with the highest bitrate conversion and using an encoder recommended by someone who seemed to really know his stuff, the differences were all to apparent. That was with my old system, I dread to think how much difference the new one would show.
