flac dev - Sep 2004 - 24-bit audio?

Using the FLAC frontend with flac v1.0.2, I tried to encode a recently
recorded 24-bit mono wav to flac, but received the following error:

options: -P 0 -b 4608 -m -l 12 -e -q 0 -r 0,6 -R 0
gpt2002-06-01mono.wav: ERROR: unsupported bits per sample 24

So, I tried to encode a stereo 24-bit wave file... same error.

I'm using the .exe of flac v1.0.2 under Windows 2000.  The wave files can be
downloaded from:

http://mikewren.com/audiotests/gpt2002-06-01mono.wav
http://mikewren.com/audiotests/gpt2002-06-01stereo.wav



Can anyone else reproduce this error?  What's the resolution?

This error means just what it says...flac 1.0.2 doesn't support 24-bit
samples.  The code in CVS appears to, though, so you may want to try that.

According to
http://flac.sourceforge.net/format.html#metadata_block_streaminfo :

"FLAC supports from 4 to 32 bits per sample. Currently the reference
encoder
and decoders only support up to 24 bits per sample. "

This is why I'm confused.  I though one of the benefits of FLAC was it's
ability to encode in word lengths longer than 16 bits.
