if you don't want to patch the pd-sources and have no urge for an 
external, you could as well try to read the soundfile as raw-data with 
[soundfiler] (probably skipping the first N bytes with the appropriate 
flag at the open-message) into a fixed-sized array (as many bytes as 
you want to read).
then do the parsing with [tabread]
