I can't find the Effect 'Scientific Filter' in Audition CS6

Hi,

I'm currently trying Audition CS6 (I know that it is old ...). I am not able to find the Effect 'Scientific Filter' under 'Effects > Fiter and EQ'. There are only the filters

FFT Filter, 3x Graphical Equalizer (with 10, 20 and 30 bands), Notch und Parametrical Equalizer available.

Any help appreciated,

kind regards,

Hans
