Audio Quality Confusion. >.>

post #1 of 7
Thread Starter 
After reviewing a few different websites referring to audio quality and encoding methods I am curious as to the advantages that ALAC, FLAC, Apple Lossless, WAV offer over 320Kbps lossy songs.

My understanding is that the codec takes out frequencies that the human ear cannot perceive while also making other minor adjustments.Certain music is indistinguishable to the untrained at 192Kbps versus 320Kbps, but what makes lossless justified versus a song encoded at 320? Sheer bragging for the lossless format for use as it was intended?

I'm sure people will argue that it makes it sound better, but if the human ear cannot possibly hear these frequencies why would it matter?

Well one point I have is that it takes out things you can't hear, but what about things you can feel. By this I mean that lower bass frequencies are mainly felt, not heard. I can surely tell that bass is much better in lossless formats compared to mp3, much crisper with more boom .

Very good point, I didn't take that into consideration.

it is not accurate to say that lossy formats such as mp3 take out frequencies the human ear cannot perceive.

1. you can perceive sound even if you cannot hear it. frequencies far beyond human hearing can make or break how we perceive music. This is especially apparent in airness of treble and deep bass notes. Have you ever sat in a room or car where the bass hit so low that you couldn't hear it, but you could feel it and still knew it was there? did it add anything to the music or move you were listening to or watching?
2. the codec you use is not perfect and it removes information that is clearly audible.
3. if you sit down and listen to say 128k mp3, 320k mp3 and a lossless file you will be able to tell the difference if you have decent headphones or speakers and listen closely.

highs are also usually a bit crisper and not as harsh with FLAC/ALAC. It's not a huge audible difference (at least to me), but it definitely is there.

Agreed, Take one of your favorite CD's and rip them respectively,
use a nice set of cans. I never thought I could tell the difference
when my sisters boyfriend would brag, then I ripped Daft Punks "alive"
cd, and I could tell the horrible 128kbps vs 320 vs lossless. in lossless,
the claping, the feel, and clarity are improved, it sounds like im there.
