MP3 vs. AAC, Apple's "MP3"

[peranders]

Before I got my iPhone I haven't really thought anything about the differences between the common MP3 and AAC.

Since AAC is default when using iTunes I did not pay much attention when I put my CD's into the iPhone so every song are AAC at 128 kb/s. Any experience between MP3 and AAC?

All my MP3's are VBR-0 or 320K CBR, so I can't tell the difference.

However.... I understand XM Satellite uses 64K AAC3 and it sounds like a 256K MP3... a hint of aliasing on a classical piece is noticeable.

Cheers!

Might be just me but I've found that I like the sound of MP3 over AAC. I've encoded same material into mp3 and aac at same 320 bit rate and the AAC encode sounds thinner and lacks depth by my hearing.

I have not used AAC.
What i have used is
.cda = directly from CD
.wav = ripped CD
.mp3 = commpressed .wav with some losses
.flac = lossless compressed .wav
--------------------------------

My 100% favourite at this time is FLAC
if this works with iPhone, I do not know .. probably not as AAC is loss format

i have no iPod or iPhone or anything other like that
i have no mp3 player
i only use these formats in my PC, where i have one CD-player/burner (Nero)

-----------------------------------------------------------------------------------
*** FLAC = Free Lossless Audio Codec
information

A digital audio recording (such as a CD track)
encoded to FLAC
can be decompressed into an identical copy of the audio data.

Wikipedia - Free Lossless Audio Codec
FLAC - Official Website
Winamp - FLAC Plug-ins

I use the excellent flac encoder and audio format converter called
foobar2000 - is 100% freeware, can be downloaded from here
foobar2000 - media player & converter

as told in my topic here in forum:

Mr Uppställning, the question was about AAC compared with MP3. I'm not particularly help with the fact that you don't know a thing about AAC.
