The trick is having a very good anti-aliasing filter just like the FIR in a
high end ADC or SRC or very good mastering processors. An IIR just won't
work well due to the phase shifting and low order stop band attenuation. I
don't think Pd has anything built in other than fexpr~ and coefficient
se
I don't understand.
can you share your patch?
thanks

yeah, but what I found is that it doesn't get that much bet

No, they're all multiples of the fundamental frequency. You can debate wether
the 1st harmonic or 1st partial is the

wether the 1st harmonic or 1st partial is the fundamental, people use this
in different ways. I see the fundamental as the first par

recently I found out the results were kinda terrible a
Also try arctangent in place of tanh. Its asymptotic behavior is
1/x instead of e^(-x) which makes for softer clipping.
I often make a big table to speed up the atan lookup using tabread4~ although
you have to be careful at the table limits.

sometimes there is no other solution.

ok yeah, i guess i mean, "nicer" in a way that doesn't alias so bad.
seems oversampling and filtering is the way to go with that, but just
wondering if there's some cheap way to avoid aliasing with distortion,
without oversampling too much?

hello,
I think "nicer" is really subjective.
tabread4~ is the faster algorithm. (then, put whaterver curve you want in the
table)
you can have a look at nusmuk-audio for different distortion algorithm,

I'm looking for something with a slightly better saturation character than
tanh~, but with not much more than about 4 times the CPU usage. Was
thinking of just upsampling and filtering tanh~ in a subpatch, but does
anyone else have a decent saturation algorithm that might be better?
