[sdiy] Audio Anti Aliasing Filter

[Scott Gravenhorst]

What are people here using for audio anti-aliasing filters?  

I'm looking for something simple.  In my own mind, I'm thinking state
variable lowpass with unity Q and cutoff of some 20 kHz for sample rates of
44.1 kHz and above.  

Are there better or simpler?
