Yes, this is understandable.  'Reference encoder and decoders'
refer to the implementations in libFLAC that transfrom raw PCM
to FLAC and vice-versa.  The command-line 'flac' is what parses
a WAVE file into raw PCM and feeds it to the reference encoder.
This is the part that did not have 24-bit support until recently.

flac CVS has it and the next release will be in 1-2 weeks.  I
have been writing unit tests to cover all the new stuff, but I
might still do a short beta.
