[Flac-dev] 24-bit audio?

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.

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.
