Have a look at
<http://kokkinizita.linuxaudio.org/linuxaudio/downloads/tapesaturation.png>
This shows the tranfer function (recorded magnetic signal as
a function of the input) for three values of the HF bias.
What is your guess at how many studios correctly biased their recorders?
The orange trace in your graph looks like fairly soft saturation. Do you
think under-biasing like that would have been common during the time tape was
common, or would most facilities have correctly biased up to the more linear
curve with harder saturation?
The only effect that remains in a complete simulation
is
the result of the EQ applied to the signal to be recorded.
The inverse is applied on playback? Wouldn't a high cut shelf type filter
applied to a clipped signal make it sound a little more like soft saturation?
