[PD] soundfiler and raw files

[Krzysztof Czaja]

hi,

yes, as it seems open_soundfile() routine treats headersize==0 as an
indication that a caller wants to deduce the header from a file.  Thus
-raw flag does not mean a headerless file, but a file with a header
format known only to the user.  But since you have prepended one zero
at the beginning of the data, then just skip this zero with '-raw 4 1 4 l'
(the header size is in bytes, not in samples).
