Aliasing in Satin?

[Robert Randolph]

So, what's up with this? intended? Bug?

Hard to judge without at least a screenshot of what settings were chosen on Satin, especially at which input level, and how the circuit headroom was set up.

Minimum aliasing would occur at maximum circuit headroom, since the tape part itself is upsampled 4x, and the circuit part is 2x (using 44k1 or 48k project SR).
A last source of aliasing could be the soft-clip option on the output. No oversampling is used there, since otherwise peaks wouldn't get stopped from exceeding the 0dBFS limit (due to the Gibbs effect).

As far as I read it, that guy sent a sine at ca. 0dBFS through Satin with the gain maxed out. If you use Satin like that in your mix, you have other problems that aliasing . Use proper gain staging...

I'm simply curious about the causeof it, not about the practicality of it.

Sascha provided an excellent answer. Thank you.

Fabfilter Saturn at 8x oversampling will not do this.
