Does anyone have any ideas on specifications or models for spectral tilt.
By spectral tilt, I mean mis-matched spectral responses caused by different
microphones, transmission lines. Just to obtain a cursory idea of the
effects of spectral tilt, up until now I have been using either a simple 
first-order low-pass or high-pass filter, but these do not really provide a 
stern enough test. If anyone has any public domain implementations
of filters representative of transmission lines / different microphones, or 
if they know where I can find them, please could you let me know.

Thanks,
