View Full Version : Apple Lossless - Bitrate Indication

Hi Dean, kdf, etc.

[APOLOGIES for posting this at the top level but
I've lost track of where the discussion in the previous, related posts
got to ...]

[OS X 10.2.8, iTunes, SlimServer_v2004-05-19.dmg, Firmware V23,
Wireless, BitrateLimiting=0]

I finally ripped a CD using Apple Lossless:
it plays back fine on my Squeezebox via the digital out.

I note that the Bitrate shows up (on the server page & on the player)
as "...kbps CBR".

I know it's pedantic but I thought that Apple Lossless varied the bitrate
through the file [although I am happy to be told that I'm wrong on this],
so shouldn't it just say "VBR" (without a number)
or (even better?) "Lossless 1411kbps" or "AL 1411kbps" ...?

[Actually this opens up a whole philosophic debate on
how the bitrate of Apple Lossless (or indeed any other lossless coding)
should be indicated ...
.... as it is lossless & recovered transparently one could argue that
it shouldn't be the bitrate at which the compressed data is recovered
that should be shown
but instead the bit rate of the original data?
(DVD-A does something along these lines with MLP,
it typically shows for example only something like "MLP 24/96"
not the degree of packing that was achieved.)

However, going back to the SlimServer/Squeezebox case,
it would clearly be confusing/wrong to show 1411kbps CBR
on the server/player because this would not tally with
the Duration & File Length information shown ...
.... that's why something like "Lossless 1411kbps" / "AL 1411kbps"
might be worth considering!

Just a small digression :-)]

Regards

Mike

you could also NOT report bitrate becuase becuause its alreayd obvious that its
an Apple Lossless from teh song info :)

Good point :-) I wish I had thought of proposing that! :-O

On reflection though ...
the File Format info says "Apple AAC, Lossless or Movie",
so for 'elegance' this would need to be broken down into two distinct formats:
"Apple AAC or Movie" that did report a bitrate
and "Apple Lossless" that did NOT report a bitrate
[or if it is not to be broken down then
I would stick with the proposal of "ALC 1411kbs"].

Aside from the issue of the number of boxes to tick
on the File Types page, why not separate them anyway ...?

Just curious ...

[Actually, that there is time for all this digression is a reflection of
how solid I find the latest nightly builds are :-)]
