Secrets of iTunes and iPod, music server

The author says apple 128 coding transparent enough for most music and
160 for more difficult classical. He has both technical and musical
basis for saying so, and as also based on subjective listening.
Provides info on getting different musical formats unto ipods for
correct access.

After reading it occurs to me this makes it possible to set up a mac
based system with remote to control entire music collection and playbac.
A mac mini for about $500 with the footprint of a cd case now has
frontrow' which works with a remote to control itunes and other
functions. With an external largish drive even lossless coding could be
used.

Or Buy an Apple TV much cheaper, does the same thing.

Apple's AAC is highly tuned, but it's still proprietary. LAME MP3
is 'free' and works just as well, and on more platforms.

Codecs have been compared extensively at lower and middle bitrates,
on hydrogenaudio.org.

It is not.

AAC is more advanced than mp3, creates smaller files with the same
quality or better quality with the same size.

My bad. I was confusing AAC per se with iTunes AAC-encoded tracks with
DRM.

Only at lower bitrates, viz. the hydrogenaudio tests
* w w w .listening-tests.info/
. And MP3 does work on more platforms and devices than AAC.

From the soundexpert pages, it is not clear that any of the top performers
are signficantly different at higher bitrates. Below 128 , AAC is
usually considered a safer choice than MP3.

What's being encoded also matters, e.g. a person here ABX'd AAC artifacts
on a couple of tracks at ~220 VBR.

AAC's Hydrogenaudio wiki page is here

listing pros and cons.

Maybe. But actually: as long as my own platform supports it - I don't
care, because I don't share.

Wasn't it normally said it's below 160?

Whether that's said or not, the tests show that the best LAME and AAC
codecs perform audibly the same down to 128, for most tracks, within the
margins of error (Sebastian Mares's hydrogenaudio tests show error bars,
but soundexpert doesn't seem to display those in a way I can parse).

FWIW, my archiving/home listening is via lossless Flac, and I use
192 VBR LAME MP3s for my iPod...I'm sure AAC files would sound just as
good.

No need to move your computer or buy another one. Take a look at
this.

I rip at 256kbs and store on a second 256g hard drive. I have about
650 cds ripped. You can browse by all the significant track
attributes as well as use itunes playlists.
