Hi,
Does anyone know if boards like the ADAU 1467 etc. can Emulate the SMSL sound color options (Rich, Tube), which I believe purposefully increases H2 and H3 distortion to preset amounts?
I was thinking of a project with a control knob that could control this. I was not sure if SigmaStudio could do fixed H2/H3 ratio and then insert it into the output signal at a variable amount based on the control knob.
Thanks!

The built-in DSP functions in most DSP chips don't support harmonic generation. Some of the more powerful DSP chips could be custom coded to do it.
Easiest way to play around with 2nd and 3rd harmonic distortion is to use ESS dac chips. They have I2C control registers to adjust those harmonics. ESS says the feature is there to help compensate/reduce distortion in the output stage due to things like mismatched component values. However, the harmonic compensation registers can be used for any purpose one wishes. As to whether or not intentionally added distortion sounds better, IME it does not. Analog circuits that produce a little low order HD may sometimes sound 'better' for reasons other the increased distortion.
