[CM] ITD/ILD filter in Snd-8(.6)

[Jacek M. Holeczek]

Hi,
in the article:
	http://www.aip.org/pt/nov99/locsound.html
in the Figure.2, the author shows the "calculated" interaural level
differences (ILD).
For my purposes, I would like to play with ITD/ILD a little bit in Snd.
Does anyone know where to find any parameterization for such curves?
I would like to "implement" an ITD/ILD filter in Snd (for example, left
channel is unchanged, right channel = left channel after ITD/ILD filter).
Thanks in advance,
Best regards,
Jacek.
