Ok I will post MediaCoder instructions soon.
***Nerdy Tech Speak alert***
@jHoff80: You are right, you should always encode from the source, so if you took your music off of CD's, then you should re-import them as ACC+ rather than re-encode the mp3's.
BUT, there is something called Downsampling. If you have a 320 kbs MP3 that takes up 10mb of data, downsampling it to 1mb AAC+ will still yield an OK result because there is enough data to work with.
Also, downsampling an AAC is ok because the codec is intelligent enough to not re-encode the entire stream but remove data and optimize it for the lower bitrate.
So encoding a CD to AAC+ and a bigger AAC to AAC+ is basically the same.
Yes, I know 48 kbs is pretty low in terms of bitrate. And I would never ever Master audio for professional use that way.
BUT, I have done years of research on Psychoacoustics modeling. I know the facts of what people can actually hear, and what is a placebo effect when people 'claim' to hear a difference in quality.
For anyone on this board who is listening to music just for the music, and not an audiophile interested in pure quality...it is good enough.
Basically ask yourself this = are you OK with listening to music on a clear FM radio station? Do I want quantity over quality? Do I listen to my Pre on crappy $20 earbuds? If so, then 48-80kbs AAC+ is good enough quality.
jHoff80, have you HEARD an 80Kbs AAC+ file? Its pretty amazing.... considering its so small..
