another question. Does FLAC need the metadata at the beginning of a file. Assume
you open a FLAC file in VirtualDub, for example. When you cut out the first half
of the WAV and the write out an AVI, the first half of the data is missing,
which includes the fLaC magic number and the metadata. Is this file still
readable then? I think you should put the marker and the metadata into the
WAVEFORMATEX (or WAVEFORMATEXTENSIBLE).

I don't know if you do this, but you said, that all data is placed in the data
area.
