There are three seperate statements here, so I'll answer them seperately.

No! That's what you said:

"The second WAV file will sound noticably lower quality than either of the first two files."

Your the one who said:

"The lossy file will probably sound almost identical (if not identical) to the original WAV file."

How can a "lossy file" sound identical to the original WAV?

This thread isn't about the transparency of "lossy files" in the first place so I have no idea why you're mentioning it.

Huh? What "upconverter"? Please explain.

This thread is about the decoding of AAC files to WAV files. Nothing else.

FACT:
There is zero quality loss when decoding AAC to WAV. The resulting WAV will sound exactly the same as the AAC file.

One could also say that the whole point of a lossless algorithm is that you don't lose information when converting to it...

PCM is not even a "lossless" format. It's uncompressed audio. By definition you can't "lose" anything.

True that. But wouldn't the AAC->PCM conversion be considered a lossless algorithm?

 

[milkpowder]

^ ^ Fair enough.

Yes, it is.


"fordgtlover" post's are bugging me. I'm sure there is some simple misunderstanding, but the "upconverter" has me intrigued

or miswording.

Where does the upconverter get the information to add back in to create the original WAV file to enure it's the same as the original? As I previously stated - try it for yourselves and make your own mind up.

I'm sorry but Evilking is right. You are talking nonsense. And why should he waste timing explaining to you why you are talking nonsense if you haven't even bothered to check your stories before you start giving "advice". The wav file created from a lossy file (barring software or hardware errors) contains the exact same information as the lossy file.

 

[fordgtlover]

Sorry for the confusion. I re-read my statement and realise that it is wrong due to me thinking about one thing and writing about another. For some reason I thought the OP wanted wanted the AAC file to be the same as the original WAV.

I have edited the post to leave the only sensible, and on topic, comment in the post. (hopefully that's not too contentious)

My apologies to the OP and the thread.




By upconvert I broadly mean decompress.

It's okay fordgtlover. Like I said before, I only burn the disc without having to convert the files into anything prior to burning. I just want to be able to listen to the songs in the same quality as I would when I'm listening on my PC. I appreciate all the replies in this thread and I've learned quite a few.

You wont loose any sound quality or audio data.
Cause AAC to PCM decoding is a lossless process.
