The loris opcodes can read SDIF files created by the Loris library,
but not necessarily those created by hetro (if that is what you have
tried). By the way, the public Csound CVS is still out of date by
more than a month due to the SourceForge CVS failure in March; if
you use the 5.01 "release" sources from the SourceForge download
page, then there is also a Loris source package there that can be
simply unzipped on top of the Csound sources.

There is no utility specifically for this purpose, but you can perform
the analysis using the Loris Python module. For example, to create
'test.sdif' from 'test.aiff', start the Python interpreter,

python

and then type these commands:

import loris
f = loris.AiffFile('test.aiff')
a = loris.Analyzer(40, 80)
loris.exportSdif('test.sdif', a.analyze(f.samples(), f.sampleRate()))

this writes the SDIF file. Note that the numbers specified for
loris.Analyzer() are important and need experimenting to find the
best sound quality; the values above are only an example.
To get more information about loris.Analyzer(), type this:

help(loris.Analyzer)
