This will allow the same type of high-frequency attenuation that the MMA IASIG Level 2 filtering model with its 'reference frequency' and 'attenuation ratio' parameters affords. Use of a cutoff frequency is consistent with the filtering type for distance and angular attenuation for ConeSound and AuralAttributes. The filter methods will likely be overloaded in some future extension of this interface.<P><P><DL><DT><B>Since:</B></DT> <DD>Java 3D 1.3</DD><DT><B>See Also:</B><DD><A
