AIFF files on MacOS X are not recognized as AIFF files
by flac. My AIFF were generated by iTunes or by Amadeus
II. flac suggests treating them as raw files.

for the command-line encoder to recognize AIFF files they
must end in .aif or .aiff (it's not case-sensitive so
.AIFF is also OK) or have an AIFF header.

it's possible that the AIFF file has something that flac
does not deal with, can you host one of the files
somewhere?

also, if you include the --force-aiff-format option to
flac, does that work?

I generated some new AIFF files with Amadeus, and it seems
to work (my original bug report should probably be
corrected). But some files are still unrecognized:

I've read the header of the problematic files and it has a
field named AIFCFVER while the recognized files have the
AIFFCOMM field.

Using the --force-aiff-format won't work.

Here is an example file generated by copying a file from CD
by dragging it to the desktop using OS X Finder.

I've done some research on this. Apple generates
AIFF-C/AIFC/'sowt' files in iTunes and when copying files
from the CD.

Info on the AIFC format is here:
http://developer.apple.com/documentation/QuickTime/INMAC/SOUND/imsoundmgr.36.htm

Although AIFC is supposedly a compressed format, 'sowt'
('twos' (complement) backward) is an encoding indicator, not
a compression.

Apparently oggenc and lame have code to handle AIFC/'sowt'
encoding. I'm sure they wouldn't mind if someone filched
that bit of code.. :)

Hope this helps.

Followup from yesterday.

I did more poking. It seems the 'sowt' AIFC format is just a
little-endian AIFF. I hacked together some code that works
and sent them on to Josh.

*bump*

1.1.2-osx-ppc still doesn't do it.
come on don't make me transcode from AIFC to AIFF before I flac... =]

(btw thanks a million for all your work josh, can't tell you how much we
appreciate it!)
