The audio data will be exact.  FLAC stores only the 'fmt ' subchunk
(which is metadata) and the 'data' subchunk (which is the audio
data).  It does not store other subchunks.

If your wave file is one 'fmt ' subchunk followed by one 'data'
chunk, the decoded wave file will be identical to the original.
