I have renewed my love for 2 channel audio since the purchase of my Peachtree iNova and am wanting to get the best sound out of it and my Rocket RS-450's. I mainly just listen to Apple iTunes and high res from HD tracks. Anyway, I saw that I can convert songs from say 192kbps to 1411 kbps via converting it from the lower kbps to the higher. Now I have played with it and am not noticing much of a difference switching between the two.

No, the loss in quality from using a lossy encoder is permanent. Converting such files to an uncompressed or lossless format will make no difference other than larger file sizes.

That's what I thought. It's totally redundant. Unless the original source is higher kbps. Taking a lower kbps file from Apple iTunes and converting to apple lossless is pointless. I hear no difference.

The process of playing those files already performs the conversion you did so that's another reason for not doing it .

It does not make sense unless your player does not support Apple's format.

why would one expect to hear a difference?
when the original lossless file was compressed to 192k/whatever, all of the extra (unnecessary) data was thrown out (at the algorithm's request). that data is gone forever. you cannot convert back since the data has already been lost.

if i take a large jpg/photo and resize it to 40x40 pixels (thumbnail), would you expect to be able to resize the thumbnail back to full size in the original quality?

Yeah, with this type of conversion. Put poo in you'll get poo out.

One thing is interesting to note: placebo effect did not work on him! So even though the new file had bigger numbers, and he probably had some expectations of better sound, his ears properly told him there was no improvement.

Exactly. Just because I saw a significant increase in the kbps when I converted it to lossless, I did have higher expectations but when playing back the original and the converted. yeah, there was absolutely no difference. I just wish itunes would start offering high res music then all will be okay.

Just for laughs, convert an uncompressed file to Apple Lossless and AAC 256 (or 192) and see if you can tell a difference.

Lord knows I will pay extra if they ever offer this...
The current AAC 265 files are not that bad though...

What’s worse is people ripping their CDs using a lossy codec. I always used either ALAC or FLAC.

iTunes is a platform - for me - to explore music. When I want to buy music, I'll go to Qobuz for exemple; they are offering high res music files.

JBL 4429 monitor speakers - McIntosh integrated MA 7000 - Only digital HR music played through Mac Mini with VOX player - Pop, rock, oldies, jazz, blues, indie.

Not to parse words, but that is not the placebo effect. That would be a bias effect. But I get your point I think. If you were to believe these forums you might think that your ears/brain will NEVER tell you the truth. Which is, of course, ridiculous.
