[PD] soundfiler dealing with floats

Having a headache saving floating point samples with Soundfiler. It
works fine, and I guess this is not really a Pd problem, but my editor
(CoolEdit Pro, winNT) can't open Sun/Next files which use floats (doh)

Similarly Soundfiler can't save wav or aiff using floats, only Sun/Next
(doh) :(

I can't seem to write a floating point sound as raw data either - only
as ASCII text using 'write' message to an array, and the editor takes
ages to interpret the text..... :(

I could 'con' CEP to open the Next floating point files as raw data,
then manually cut off the header blip - except I can't find the right
floating point format in CEP. The options are:

32-bit IEEE float (0.24) 
32-bit IEEE float (16.8)
32-bit IEEE float (24.0)
24-bit packed Intel PCM
24-bit packed Motorola PCM

and then 'Offset input data by: 0 +1 +2 +3'.

Anyone have any suggestions? (apologies for this not really being a
'pure-pure-data' issue, as it were).
