NO, the full spectrum is saturated, of course. You cannot limit some frequencies and let others pass-through! (you could, of course, but...)
Frequencies are saturated in a frequency-dependent way.
An example: if you distort 3kHz, you get 6kHz, 9kHz and so on.
If you distort 12kHz, you get 24kHz, 36kHz, etc. (if samplerate is high enough, of course). So, why distort 12kHz if you don't get any audible result?
This is what I described in an early post. A frequency dependent saturation.
This is just one aspect.
The other one is a variable, dynamic, equalisation to follow real-tape behaviour.
These two things aren't separated, they are integrated in one algorithm.
How does it sound for you is the only important thing, anymay
(otherwise it is nerdy gimnick)
